Web Content Accessibility Guidelines 2.0  

NSDL National Science Digital Library

Dated August 24, 2001, this online working draft of Web content accessibility guidelines comes from the World Wide Web Consortium (WC3). The aim of this accessibility project is to make Web more navigable to people with disabilities. The first draft of the guidelines was published in 1999 (mentioned in the May 7, 1999 Scout Report). This newer version incorporates reader feedback, covers a wider range of technologies and uses wording that may be understood by a more varied audience. Four guidelines, each containing several "checkpoints," an introduction and glossary are included. A hypertext Table of Contents takes readers to desired sections.

Web Accessibility and Guidelines  

NASA Astrophysics Data System (ADS)

Access to, and movement around, complex online environments, of which the World Wide Web (Web) is the most popular example, has long been considered an important and major issue in the Web design and usability field. The commonly used slang phrase ‘surfing the Web’ implies rapid and free access, pointing to its importance among designers and users alike. It has also been long established that this potentially complex and difficult access is further complicated, and becomes neither rapid nor free, if the user is disabled. There are millions of people who have disabilities that affect their use of the Web. Web accessibility aims to help these people to perceive, understand, navigate, and interact with, as well as contribute to, the Web, and thereby the society in general. This accessibility is, in part, facilitated by the Web Content Accessibility Guidelines (WCAG) currently moving from version one to two. These guidelines are intended to encourage designers to make sure their sites conform to specifications, and in that conformance enable the assistive technologies of disabled users to better interact with the page content. In this way, it was hoped that accessibility could be supported. While this is in part true, guidelines do not solve all problems and the new WCAG version two guidelines are surrounded by controversy and intrigue. This chapter aims to establish the published literature related to Web accessibility and Web accessibility guidelines, and discuss limitations of the current guidelines and future directions.

Enhancing Accessibility of Web Content for the Print-Impaired and Blind People  

NASA Astrophysics Data System (ADS)

Blind people and in general print-impaired people are often restricted to use their own computers, enhanced most often with expensive, screen reading programs, in order to access the web, and in a form that every screen reading program allows to. In this paper we present SpellCast Navi, a tool that is intended for people with visual impairments, which attempts to combine advantages from both customized and generic web enhancement tools. It consists of a generically designed engine and a set of case-specific filters. It can run on a typical web browser and computer, without the need of installing any additional application locally. It acquires and parses the content of web pages, converts bi-lingual text into synthetic speech using high quality speech synthesizer, and supports a set of common functionalities such as navigation through hotkeys, audible navigation lists and more. By using a post-hoc approach based on a-priori information of the website's layout, the audible presentation and navigation through the website is more intuitive a more efficient than with a typical screen reading application. SpellCast Navi poses no requirements on web pages and introduces no overhead to the design and development of a website, as it functions as a hosted proxy service.

Web accessibility and open source software.  

PubMed

A Web browser provides a uniform user interface to different types of information. Making this interface universally accessible and more interactive is a long-term goal still far from being achieved. Universally accessible browsers require novel interaction modalities and additional functionalities, for which existing browsers tend to provide only partial solutions. Although functionality for Web accessibility can be found as open source and free software components, their reuse and integration is complex because they were developed in diverse implementation environments, following standards and conventions incompatible with the Web. To address these problems, we have started several activities that aim at exploiting the potential of open-source software for Web accessibility. The first of these activities is the development of Adaptable Multi-Interface COmmunicator (AMICO):WEB, an infrastructure that facilitates efficient reuse and integration of open source software components into the Web environment. The main contribution of AMICO:WEB is in enabling the syntactic and semantic interoperability between Web extension mechanisms and a variety of integration mechanisms used by open source and free software components. Its design is based on our experiences in solving practical problems where we have used open source components to improve accessibility of rich media Web applications. The second of our activities involves improving education, where we have used our platform to teach students how to build advanced accessibility solutions from diverse open-source software. We are also partially involved in the recently started Eclipse projects called Accessibility Tools Framework (ACTF), the aim of which is development of extensible infrastructure, upon which developers can build a variety of utilities that help to evaluate and enhance the accessibility of applications and content for people with disabilities. In this article we briefly report on these activities. PMID:19565384

Combining Social Networks and Semantic Web Technologies for Personalizing Web Access  

NASA Astrophysics Data System (ADS)

The original purpose of Web metadata was to protect end-users from possible harmful content and to simplify search and retrieval. However they can also be also exploited in more enhanced applications, such as Web access personalization on the basis of end-users’ preferences. In order to achieve this, it is however necessary to address several issues. One of the most relevant is how to assess the trustworthiness of Web metadata. In this paper, we discuss how such issue can be addressed through the use of collaborative and Semantic Web technologies. The system we propose is based on a Web-based Social Network, where members are able not only to specify labels, but also to rate existing labels. Both labels and ratings are then used to assess the trustworthiness of resources’ descriptions and to enforce Web access personalization.

Web-accessible cervigram automatic segmentation tool

Uterine cervix image analysis is of great importance to the study of uterine cervix cancer, which is among the leading cancers affecting women worldwide. In this paper, we describe our proof-of-concept, Web-accessible system for automated segmentation of significant tissue regions in uterine cervix images, which also demonstrates our research efforts toward promoting collaboration between engineers and physicians for medical image analysis projects. Our design and implementation unifies the merits of two commonly used languages, MATLAB and Java. It circumvents the heavy workload of recoding the sophisticated segmentation algorithms originally developed in MATLAB into Java while allowing remote users who are not experienced programmers and algorithms developers to apply those processing methods to their own cervicographic images and evaluate the algorithms. Several other practical issues of the systems are also discussed, such as the compression of images and the format of the segmentation results.

Tool independence for the Web Accessibility Quantitative Metric.  

PubMed

The Web Accessibility Quantitative Metric (WAQM) aims at accurately measuring the accessibility of web pages. One of the main features of WAQM among others is that it is evaluation tool independent for ranking and accessibility monitoring scenarios. This article proposes a method to attain evaluation tool independence for all foreseeable scenarios. After demonstrating that homepages have a more similar error profile than any other web page in a given web site, 15 homepages were measured with 10,000 different values of WAQM parameters using EvalAccess and LIFT, two automatic evaluation tools for accessibility. A similar procedure was followed with random pages and with several test files obtaining several tuples that minimise the difference between both tools. One thousand four hundred forty-nine web pages from 15 web sites were measured with these tuples and those values that minimised the difference between the tools were selected. Once the WAQM was tuned, the accessibility of 15 web sites was measured with two metrics for web sites, concluding that even if similar values can be produced, obtaining the same scores is undesirable since evaluation tools behave in a different way.

Accelerating Web Content Filtering by the Early Decision Algorithm  

NASA Astrophysics Data System (ADS)

Real-time content analysis is typically a bottleneck in Web filtering. To accelerate the filtering process, this work presents a simple, but effective early decision algorithm that analyzes only part of the Web content. This algorithm can make the filtering decision, either to block or to pass the Web content, as soon as it is confident with a high probability that the content really belongs to a banned or an allowed category. Experiments show the algorithm needs to examine only around one-fourth of the Web content on average, while the accuracy remains fairly good: 89% for the banned content and 93% for the allowed content. This algorithm can complement other Web filtering approaches, such as URL blocking, to filter the Web content with high accuracy and efficiency. Text classification algorithms in other applications can also follow the principle of early decision to accelerate their applications.

Unifying Access to National Hydrologic Data Repositories via Web Services  

NASA Astrophysics Data System (ADS)

The CUAHSI hydrologic information system (HIS) is designed to be a live, multiscale web portal system for accessing, querying, visualizing, and publishing distributed hydrologic observation data and models for any location or region in the United States. The HIS design follows the principles of open service oriented architecture, i.e. system components are represented as web services with well defined standard service APIs. WaterOneFlow web services are the main component of the design. The currently available services have been completely re-written compared to the previous version, and provide programmatic access to USGS NWIS. (steam flow, groundwater and water quality repositories), DAYMET daily observations, NASA MODIS, and Unidata NAM streams, with several additional web service wrappers being added (EPA STORET, NCDC and others.). Different repositories of hydrologic data use different vocabularies, and support different types of query access. Resolving semantic and structural heterogeneities across different hydrologic observation archives and distilling a generic set of service signatures is one of the main scalability challenges in this project, and a requirement in our web service design. To accomplish the uniformity of the web services API, data repositories are modeled following the CUAHSI Observation Data Model. The web service responses are document-based, and use an XML schema to express the semantics in a standard format. Access to station metadata is provided via web service methods, GetSites, GetSiteInfo and GetVariableInfo. The methdods form the foundation of CUAHSI HIS discovery interface and may execute over locally-stored metadata or request the information from remote repositories directly. Observation values are retrieved via a generic GetValues method which is executed against national data repositories. The service is implemented in ASP.Net, and other providers are implementing WaterOneFlow services in java. Reference implementation of WaterOneFlow web services is available. More information about the ongoing development of CUAHSI HIS is available from http://www.cuahsi.org/his/.

Authentication, authorization, accounting, and encryption are goals of security strategies for web information being accessed that is private. The definition of these terms is as follows: • Authentication - validation that the individual (or system) is who they say they are • Authorization - validation that the individual (or system) accessing information is authorized to do so • Accounting - records are kept of what is accessed • Encryption - use of a ‘scrambling’ algorithm such that the information can pass securely across the public Internet without being intelligible; information is specifically ‘unscrambled’ or deencrypted at the receiving end Many tools can be used to meet these goals. The degree to which the goals are met is determined by how we use these tools. Methodologies similar to TSEC[1] and ITSEC[2] can be used to determine the appropriate level of protection for a particular web application. This poster describes a set of effective strategies for web application security and the level of protection each strategy provides.

Accessing Streamflow Data via the Worldwide Web  

NSDL National Science Digital Library

This is a computer-based activity in which students retrieve data from websites maintained by the US Geological Survey (USGS) and the National Weather Service (NWS), and then use that data to test different hypotheses regarding streamflow and precipitation. Students import data from web sites into a spreadsheet program where they can construct scatter plots and perform simple statistical tests. The activity has two components, the first focusing on relations between streamflow and drainage basin characteristics (drainage area, slope, precipitation), the second focusing on trends in annual precipitation at two locations in the USA: Burlington, VT, and Boulder, CO. As part of the second component, students conduct a statistical test to determine if the long-term trends in precipitation are significant.

What new mothers' favorite web sites and features tell us about designing web-based health promotion: a content analysis.  

PubMed

Abstract Objective: Unmet health needs experienced by new mothers may potentially be reduced by the use of Internet-based information, advice, decision support, and social networking. New mothers' Web site preferences must be understood in order to develop successful Internet-delivered healthcare information. The purpose of this study is to determine the Web site preferences of new mothers in order to better design health resources distributed through the Internet. Materials and Methods: Data were derived from two open-ended questions in a larger survey of new mothers of varying incomes and racial/ethnic groups (n=145). The questions focused on mothers' favorite Web sites and their favorite aspect of the Web sites. Content analysis was used to condense data into descriptive categories. Results: Mothers most frequently chose commercial search engines, followed by social networking sites, as their favorite Web sites. Mothers' most frequently mentioned favorite attributes of the Web sites were, first, the ability to interact with other users, and then ease of navigation, access, and use. Except for a difference in favorite Web site associated with maternal age, Web sites and their most liked attributes did not differ by demographic characteristics. Conclusions: New mothers' Web site preferences offer preliminary guidance for designers of e-health resources for this population. An expanded survey with more detailed questions about preferences and devices would further refine this knowledge base. PMID:24053113

Web Services Provide Access to SCEC Scientific Research Application Software  

NASA Astrophysics Data System (ADS)

Web services offer scientific communities a new paradigm for sharing research codes and communicating results. While there are formal technical definitions of what constitutes a web service, for a user community such as the Southern California Earthquake Center (SCEC), we may conceptually consider a web service to be functionality provided on-demand by an application which is run on a remote computer located elsewhere on the Internet. The value of a web service is that it can (1) run a scientific code without the user needing to install and learn the intricacies of running the code; (2) provide the technical framework which allows a user's computer to talk to the remote computer which performs the service; (3) provide the computational resources to run the code; and (4) bundle several analysis steps and provide the end results in digital or (post-processed) graphical form. Within an NSF-sponsored ITR project coordinated by SCEC, we are constructing web services using architectural protocols and programming languages (e.g., Java). However, because the SCEC community has a rich pool of scientific research software (written in traditional languages such as C and FORTRAN), we also emphasize making existing scientific codes available by constructing web service frameworks which wrap around and directly run these codes. In doing so we attempt to broaden community usage of these codes. Web service wrapping of a scientific code can be done using a "web servlet" construction or by using a SOAP/WSDL-based framework. This latter approach is widely adopted in IT circles although it is subject to rapid evolution. Our wrapping framework attempts to "honor" the original codes with as little modification as is possible. For versatility we identify three methods of user access: (A) a web-based GUI (written in HTML and/or Java applets); (B) a Linux/OSX/UNIX command line "initiator" utility (shell-scriptable); and (C) direct access from within any Java application (and with the correct API interface from within C++ and/or C/Fortran). This poster presentation will provide descriptions of the following selected web services and their origin as scientific application codes: 3D community velocity models for Southern California, geocoordinate conversions (latitude/longitude to UTM), execution of GMT graphical scripts, data format conversions (Gocad to Matlab format), and implementation of Seismic Hazard Analysis application programs that calculate hazard curve and hazard map data sets.

Characterizing user access to videos on the World Wide Web  

NASA Astrophysics Data System (ADS)

Despite evidence of rising popularity of video on the web (or VOW), little is known about how users access video. However, such a characterization can greatly benefit the design of multimedia systems such as web video proxies and VOW servers. Hence, this paper presents an analysis of trace data obtained from an ongoing VOW experiment in Lulea University of Technology, Sweden. This experiment is unique as video material is distributed over a high bandwidth network allowing users to make access decisions without the network being a major factor. Our analysis revealed a number of interesting discoveries regarding user VOW access. For example, accesses display high temporal locality: several requests for the same video title often occur within a short time span. Accesses also exhibited spatial locality of reference whereby a small number of machines accounted for a large number of overall requests. Another finding was a browsing pattern where users preview the initial portion of a video to find out if they are interested. If they like it, they continue watching, otherwise they halt it. This pattern suggests that caching the first several minutes of video data should prove effective. Lastly, the analysis shows that, contrary to previous studies, ranking of video titles by popularity did not fit a Zipfian distribution.

Web accessibility to the atomic database computing system  

NASA Astrophysics Data System (ADS)

We report on efforts to provide web accessibility to our atomic database computing system. In previous work [1], we have developed an atomic database computing system which integrates the large scale atomic data calculations for ICF applications, spectrum analysis for laser-produced plasmas, and data visualization into a single platform. This work emphasizes web accessibility and system enhancement. Multiple atomic data models, such as IONMIX (screened hydrogenic model), ATBASE (non-relativistic model) and RSSUTA (jj split relativistic model), are seamlessly incorporated into the data provider layer of the computing system using embedded databases. With the Java technology J2EE as the system infrastructure, we intend to build a web-based atomic database for hot dense plasma radiation transport modelers and ICF experimentalists. Unlike most web sites which include the static data, we will provide dynamic calculations interacting with the database system and the user interface. [1] J. Yuan, G.A.

Web Based Data Access to the World Data Center for Climate  

NASA Astrophysics Data System (ADS)

The World Data Center for Climate (WDC-Climate, www.wdc-climate.de) is hosted by the Model &Data Group (M&D) of the Max Planck Institute for Meteorology. The M&D department is financed by the German government and uses the computers and mass storage facilities of the German Climate Computing Centre (Deutsches Klimarechenzentrum, DKRZ). The WDC-Climate provides web access to 200 Terabytes of climate data; the total mass storage archive contains nearly 4 Petabytes. Although the majority of the datasets concern model output data, some satellite and observational data are accessible as well. The underlying relational database is distributed on five servers. The CERA relational data model is used to integrate catalogue data and mass data. The flexibility of the model allows to store and access very different types of data and metadata. The CERA metadata catalogue provides easy access to the content of the CERA database as well as to other data in the web. Visit ceramodel.wdc-climate.de for additional information on the CERA data model. The majority of the users access data via the CERA metadata catalogue, which is open without registration. However, prior to retrieving data user are required to check in and apply for a userid and password. The CERA metadata catalogue is servlet based. So it is accessible worldwide through any web browser at cera.wdc-climate.de. In addition to data and metadata access by the web catalogue, WDC-Climate offers a number of other forms of web based data access. All metadata are available via http request as xml files in various metadata formats (ISO, DC, etc., see wini.wdc-climate.de) which allows for easy data interchange with other catalogues. Model data can be retrieved in GRIB, ASCII, NetCDF, and binary (IEEE) format. WDC-Climate serves as data centre for various projects. Since xml files are accessible by http, the integration of data into applications of different projects is very easy. Projects supported by WDC-Climate are e.g. CEOP, IPCC, and CARIBIC. A script tool for data download (jblob) is offered on the web page, to make retrieval of huge data quantities more comfortable.

Web seismic Un ?x: making seismic reflection processing more accessible  

NASA Astrophysics Data System (ADS)

Web Seismic Un ?x is a browser-based user interface for the Seismic Un ?x freeware developed at Colorado School of Mines. The interface allows users to process and display seismic reflection data from any remote platform that runs a graphical Web browser. Users access data and create processing jobs on a remote server by completing form-based Web pages whose Common Gateway Interface scripts are written in Perl. These scripts supply parameters, manage files, call Seismic Un ?x routines and return data plots. The interface was designed for undergraduate commuter students taking geophysics courses who need to: (a) process seismic data and other time series as a class using computers in campus teaching labs and (b) complete course assignments at home. Students from an undergraduate applied geophysics course tested the Web user interface while completing laboratory assignments in which they acquired and processed common-depth-point seismic reflection data into a subsurface image. This freeware, which will be publicly available by summer 1999, was developed and tested on a Solaris 2.5 server and will be ported to other versions of Unix, including Linux.

Rating of web pages based on image content analysis  

NASA Astrophysics Data System (ADS)

With the proliferation of multimedia information on the network, automatic rating of web pages becomes more and more important for web management. Obviously image analysis is very important in these kinds of tasks. But to our best knowledge, there are no publications reported on it. In this paper, we propose a novel framework to rate webpage using image content analysis. The rated categories are in compliance with the standard utilized by most web browsers like Internet Explorer, which include Normal, Revealing Attire, Exposed Breasts and Bare Buttocks. To make the rating work feasible, we analyze the images mainly using skin detection and body region, and face detection is also used as guidance for the detection of skin and body region. After that, all the results of image content analysis are integrated to achieve content rating results for web pages. We tested our system on two data sets and demonstrated its effectiveness.

WebAlchemist: a Web transcoding system for mobile Web access in handheld devices  

NASA Astrophysics Data System (ADS)

In this paper, we describe the design and implementation of WebAlchemist, a prototype web transcoding system, which automatically converts a given HTML page into a sequence of equivalent HTML pages that can be properly displayed on a hand-held device. The Web/Alchemist system is based on a set of HTML transcoding heuristics managed by the Transcoding Manager (TM) module. In order to tackle difficult-to-transcode pages such as ones with large or complex table structures, we have developed several new transcoding heuristics that extract partial semantics from syntactic information such as the table width, font size and cascading style sheet. Subjective evaluation results using popular HTML pages (such as the CNN home page) show that WebAlchemist generates readable, structure-preserving transcoded pages, which can be properly displayed on hand-held devices.

ARCAS (ACACIA Regional Climate-data Access System) -- a Web Access System for Climate Model Data Access, Visualization and Comparison  

NASA Astrophysics Data System (ADS)

A Web-based access system to climate model output data sets for intercomparison and analysis has been produced, using the NOAA-PMEL developed Live Access Server software as host server and Ferret as the data serving and visualization engine. Called ARCAS ("ACACIA Regional Climate-data Access System"), and publicly accessible at http://dataserver.ucar.edu/arcas, the site currently serves climate model outputs from runs of the NCAR Climate System Model for the 21st century, for Business as Usual and Stabilization of Greenhouse Gas Emission scenarios. Users can select, download, and graphically display single variables or comparisons of two variables from either or both of the CSM model runs, averaged for monthly, seasonal, or annual time resolutions. The time length of the averaging period, and the geographical domain for download and display, are fully selectable by the user. A variety of arithmetic operations on the data variables can be computed "on-the-fly", as defined by the user. Expansions of the user-selectable options for defining analysis options, and for accessing other DOD-compatible ("Distributed Ocean Data System-compatible") data sets, residing at locations other than the NCAR hardware server on which ARCAS operates, are planned for this year. These expansions are designed to allow users quick and easy-to-operate web-based access to the largest possible selection of climate model output data sets available throughout the world.

System and method for authorizing access to data on content servers in a distributed network  

US Patent & Trademark Office Database

A browser capable of accessing only web pages previously authorized by a parent or supervisor of a user of the browser. In a supervisor mode of operation, a parent can browse through any accessible web site and continually add approved web sites to a database of authorized web sites. Later, in a user mode of operation, the child is capable of accessing only those web sites that have been added to the authorized web site database. In the supervisor mode of operation, the browser also generates pixel signatures based on image data contained in web pages of the authorized web sites and generates checksum values based on text data contained in web pages of the authorized web sites. The browser later compares pixel signatures and checksum values from subsequently accessed web pages to the original pixel signatures and checksum values to determine if any of the data in the authorized web pages has been changed.

Web access to the SOHO/ERNE energetic particle data  

NASA Astrophysics Data System (ADS)

ERNE is a particle instruments onboard the SOHO spacecraft. With its two sensors ERNE measures differential energy spectra of protons and helium ions in the range 1.3 - 140 MeV/n, provides integral fluxes at higher energies, and records intensities of ions from carbon to iron up to hundreds of MeV/n. A tool to access a number of ERNE data products through internet has been created. The tool offers interactive data search and display functions. A Java applet provides an interface to a set of IDL functions that handle data search and integration. The currently available data consist of 1-minute proton and helium intensities covering the time period from May 8, 1996 to June 30, 2001. From these intensities, new data sets can be constructed with a desired time resolution and energy binning. For visualisation of the generated data, the intensities can be plotted as a function of time in several optional forms of presentation. The intensities are also available for download as an ASCII text file. Supplementary web services include archived proton and helium data in four energy channels between 1.8 and 51 MeV/n ordered by Carrington rotations, and access to a solar energetic particle event catalogue. In addition, continuously updated near-real time proton and helium intensities and proton-to-helium ratio are provided as plots of 2-hour averages. These services are freely accessible at http://www.srl.utu.fi.

A content analysis of Web sites promoting smoking culture and lifestyle.  

PubMed

The present study examined smoking culture and lifestyle Web sites listed on Yahoo!, a popular Internet search catalog, to determine whether the sites were easily accessible to youth, featured age or health warnings, and mentioned specific tobacco brands. A content analysis of photographs on these sites assessed the demographics of individuals depicted and the amount of smoking and nudity in the photographs. The sample included 30 Web sites, all of which were accessible to youth and did not require age verification services to enter them. Cigarette brand names were mentioned in writing on 35% of the sites, and brand images were present on 24% of the sites. Nearly all of the photographs (95%) depicted smoking, 92% featured women, and 7% contained partial or full nudity. These results underscore the need for greater research and monitoring of smoking-related Internet content by health educators and tobacco control advocates. PMID:12564668

Web-based access to an online atlas of anatomy: the Digital Anatomist Common Gateway Interface.  

PubMed Central

A World Wide Web Common Gateway Interface package is described for accessing existing online interactive atlases of anatomy. The Web interface accesses the same 2-D and 3-D images of human neuroanatomy, knee anatomy and thoracic viscera that are currently accessed by a custom interactive atlas in distance learning courses. Although the Web interface is too slow to replace the existing atlas, it provides a parallel access path that has much broader potential for development of a distributed distance learning network in anatomy. By maintaining both access methods to the same information sources we continue to satisfy the fast interactivity needs for our local courses, while at the same time providing a migration path to the Web as the capabilities of Web browsers evolve.

Improving access to space weather data via workflows and web services  

NASA Astrophysics Data System (ADS)

The Space Physics Interactive Data Resource (SPIDR) is a web-based interactive tool developed by NOAA's National Geophysical Data Center to provide access to historical space physics datasets. These data sets are widely used by physicists for space weather modeling and predictions. Built on a distributed network of databases and application servers, SPIDR offers services in two ways: via a web page interface and via a web service interface. SPIDR exposes several SOAP-based web services that client applications implement to connect to a number of data sources for data download and processing. At present, the usage of the web services has been difficult, adding unnecessary complexity to client applications and inconvenience to the scientists who want to use these datasets. The purpose of this study focuses on improving SPIDR's web interface to better support data access, integration and display. This is accomplished in two ways: (1) examining the needs of scientists to better understand what web services they require to better access and process these datasets and (2) developing a client application to support SPIDR's SOAP-based services using the Kepler scientific workflow system. To this end, we identified, designed and developed several web services for filtering the existing datasets and created several Kepler workflows to automate routine tasks associated with these datasets. These workflows are a part of the custom NGDC build of the Kepler tool. Scientists are already familiar with Kepler due to its extensive use in this domain. As a result, this approach provides them with tools that are less daunting than raw web services and ultimately more useful and customizable. We evaluated our work by interviewing various scientists who make use of SPIDR and having them use the developed Kepler workflows while recording their feedback and suggestions. Our work has improved SPIDR such that new web services are now available and scientists have access to a desktop-based direct manipulation tool that provides them with improved support for data access and visualization.

Securing the anonymity of content providers in the World Wide Web  

NASA Astrophysics Data System (ADS)

Nowadays the World Wide Web (WWW) is an established service used by people all over the world. Most of them do not recognize the fact that they reveal plenty of information about themselves or their affiliation and computer equipment to the providers of web pages they connect to. As a result, a lot of services offer users to access web pages unrecognized or without risk of being backtracked, respectively. This kind of anonymity is called user or client anonymity. But on the other hand, an equivalent protection for content providers does not exist, although this feature is desirable for many situations in which the identity of a publisher or content provider shall be hidden. We call this property server anonymity. We will introduce the first system with the primary target to offer anonymity for providers of information in the WWW. Beside this property, it provides also client anonymity. Based on David Chaum's idea of mixes and in relation to the context of the WWW, we explain the term 'server anonymity' motivating the system JANUS which offers both client and server anonymity.

Measurement of memory access contentions in multiple vector processor systems  

SciTech Connect

The purpose of this paper is to study delays encountered when several vector processors access a common memory. Such delays may be caused by access conflicts at the memory or by contentions within the network connection processors to common memory. Because such delays are potentially the limiting performance bottleneck of common memory architectures, it is important to understand how they depend on design parameters, in particular the number of processors serviced by the common memory, the degree of memory interleaving, and the speed of the memory chips. Such understanding will make it possible to assess the performance of systems with increasing number of processors and new memory technologies. It is essential for any assessment of the future potential of common memory systems. There are three possible approaches to the study of this problem, analytical models, simulations, and measurements on existing machines. All three approaches are necessary because each has advantages and limitations. Analytical models owe their effectiveness to simplifying assumptions that need to be checked by the other two methods. In particular, stochastic methods and queueing theory offer not techniques to deal with regular memory access patterns that are common in scientific and engineering applications. Simulations can generally approximate reality more closely, however, even simulations do not replace real measurements. They are often very slow and contain assumptions that need to be tested. This paper presents a set of measurements of memory access delay performed on several computers of the Cray family under carefully controlled conditions. 9 refs., 12 figs., 1 tab.

A Privacy Access Control Framework for Web Services Collaboration with Role Mechanisms  

NASA Astrophysics Data System (ADS)

With the popularity of Internet technology, web services are becoming the most promising paradigm for distributed computing. This increased use of web services has meant that more and more personal information of consumers is being shared with web service providers, leading to the need to guarantee the privacy of consumers. This paper proposes a role-based privacy access control framework for Web services collaboration, it utilizes roles to specify the privacy privileges of services, and considers the impact on the reputation degree of the historic experience of services in playing roles. Comparing to the traditional privacy access control approaches, this framework can make the fine-grained authorization decision, thus efficiently protecting consumers' privacy.

Web service activities at the IRIS DMC to support federated and multidisciplinary access  

NASA Astrophysics Data System (ADS)

At the IRIS Data Management Center (DMC) we have developed a suite of web service interfaces to access our large archive of, primarily seismological, time series data and related metadata. The goals of these web services include providing: a) next-generation and easily used access interfaces for our current users, b) access to data holdings in a form usable for non-seismologists, c) programmatic access to facilitate integration into data processing workflows and d) a foundation for participation in federated data discovery and access systems. To support our current users, our services provide access to the raw time series data and metadata or conversions of the raw data to commonly used formats. Our services also support simple, on-the-fly signal processing options that are common first steps in many workflows. Additionally, high-level data products derived from raw data are available via service interfaces. To support data access by researchers unfamiliar with seismic data we offer conversion of the data to broadly usable formats (e.g. ASCII text) and data processing to convert the data to Earth units. By their very nature, web services are programmatic interfaces. Combined with ubiquitous support for web technologies in programming & scripting languages and support in many computing environments, web services are very well suited for integrating data access into data processing workflows. As programmatic interfaces that can return data in both discipline-specific and broadly usable formats, our services are also well suited for participation in federated and brokered systems either specific to seismology or multidisciplinary. Working within the International Federation of Digital Seismograph Networks, the DMC collaborated on the specification of standardized web service interfaces for use at any seismological data center. These data access interfaces, when supported by multiple data centers, will form a foundation on which to build discovery and access mechanisms for data sets spanning multiple centers. To promote the adoption of these standardized services the DMC has developed portable implementations of the software needed to host these interfaces, minimizing the work required at each data center. Within the COOPEUS project framework, the DMC is working with EU partners to install web services implementations at multiple data centers in Europe.

Semantic-JSON: a lightweight web service interface for Semantic Web contents integrating multiple life science databases  

PubMed Central

Global cloud frameworks for bioinformatics research databases become huge and heterogeneous; solutions face various diametric challenges comprising cross-integration, retrieval, security and openness. To address this, as of March 2011 organizations including RIKEN published 192 mammalian, plant and protein life sciences databases having 8.2 million data records, integrated as Linked Open or Private Data (LOD/LPD) using SciNetS.org, the Scientists' Networking System. The huge quantity of linked data this database integration framework covers is based on the Semantic Web, where researchers collaborate by managing metadata across public and private databases in a secured data space. This outstripped the data query capacity of existing interface tools like SPARQL. Actual research also requires specialized tools for data analysis using raw original data. To solve these challenges, in December 2009 we developed the lightweight Semantic-JSON interface to access each fragment of linked and raw life sciences data securely under the control of programming languages popularly used by bioinformaticians such as Perl and Ruby. Researchers successfully used the interface across 28 million semantic relationships for biological applications including genome design, sequence processing, inference over phenotype databases, full-text search indexing and human-readable contents like ontology and LOD tree viewers. Semantic-JSON services of SciNetS.org are provided at http://semanticjson.org.

Checking an integrated model of web accessibility and usability evaluation for disabled people.  

PubMed

A combined objective-oriented and subjective-oriented method for evaluating accessibility and usability of web pages for students with disability was tested. The objective-oriented approach is devoted to verifying the conformity of interfaces to standard rules stated by national and international organizations responsible for web technology standardization, such as W3C. Conversely, the subjective-oriented approach allows assessing how the final users interact with the artificial system, accessing levels of user satisfaction based on personal factors and environmental barriers. Five kinds of measurements were applied as objective-oriented and subjective-oriented tests. Objective-oriented evaluations were performed on the Help Desk web page for students with disability, included in the website of a large Italian state university. Subjective-oriented tests were administered to 19 students labeled as disabled on the basis of their own declaration at the University enrolment: 13 students were tested by means of the SUMI test and six students by means of the 'Cooperative evaluation'. Objective-oriented and subjective-oriented methods highlighted different and sometimes conflicting results. Both methods have pointed out much more consistency regarding levels of accessibility than of usability. Since usability is largely affected by individual differences in user's own (dis)abilities, subjective-oriented measures underscored the fact that blind students encountered much more web surfing difficulties.

EntrezAJAX: direct web browser access to the Entrez Programming Utilities  

PubMed Central

Web applications for biology and medicine often need to integrate data from Entrez services provided by the National Center for Biotechnology Information. However, direct access to Entrez from a web browser is not possible due to 'same-origin' security restrictions. The use of "Asynchronous JavaScript and XML" (AJAX) to create rich, interactive web applications is now commonplace. The ability to access Entrez via AJAX would be advantageous in the creation of integrated biomedical web resources. We describe EntrezAJAX, which provides access to Entrez eUtils and is able to circumvent same-origin browser restrictions. EntrezAJAX is easily implemented by JavaScript developers and provides identical functionality as Entrez eUtils as well as enhanced functionality to ease development. We provide easy-to-understand developer examples written in JavaScript to illustrate potential uses of this service. For the purposes of speed, reliability and scalability, EntrezAJAX has been deployed on Google App Engine, a freely available cloud service. The EntrezAJAX webpage is located at http://entrezajax.appspot.com/

The NIF DISCO Framework: facilitating automated integration of neuroscience content on the web.  

PubMed

This paper describes the capabilities of DISCO, an extensible approach that supports integrative Web-based information dissemination. DISCO is a component of the Neuroscience Information Framework (NIF), an NIH Neuroscience Blueprint initiative that facilitates integrated access to diverse neuroscience resources via the Internet. DISCO facilitates the automated maintenance of several distinct capabilities using a collection of files 1) that are maintained locally by the developers of participating neuroscience resources and 2) that are "harvested" on a regular basis by a central DISCO server. This approach allows central NIF capabilities to be updated as each resource's content changes over time. DISCO currently supports the following capabilities: 1) resource descriptions, 2) "LinkOut" to a resource's data items from NCBI Entrez resources such as PubMed, 3) Web-based interoperation with a resource, 4) sharing a resource's lexicon and ontology, 5) sharing a resource's database schema, and 6) participation by the resource in neuroscience-related RSS news dissemination. The developers of a resource are free to choose which DISCO capabilities their resource will participate in. Although DISCO is used by NIF to facilitate neuroscience data integration, its capabilities have general applicability to other areas of research. PMID:20387131

Uniform Access to Astronomical Web Services and its Implementation in SkyMouse  

NASA Astrophysics Data System (ADS)

With the progress of information technologies and astronomical observation technologies, as an example of cyber-infrastructure based sciences, the Virtual Observatory (VO) is initiated and spreaded quickly. More and more on-line accessible database systems and different kinds of services are available. Although astronomers have been aware of the importance of the interoperability, integrated access to the on-line information is still difficult. The SkyMouse is a smart system developed by Chinese Virtual Observatory project to let us access different online resource systems easier than ever. Not like some VO efforts on uniformed access systems, for example, NVO DataScope, SkyMouse tries to show a comprehensive overview for a specific object, but not to snatch as much data as possible. Stimulated by a simple "Mouse Over" on an interested object name, various VO-compliant and traditional databases, i.e. SIMBAD, NED, VizieR, DSS, ADS, are queried by the SkyMouse. An overview for the given object, including basic information, image, observation and references, is displayed in the user's default web browser. In this article, the authors will introduce the framework of SkyMouse. During the development of SkyMouse, various Web services will be called. In order to invoke these Web services, two problems must be solved, i.e. interoperability and performance. In the paper, a detailed description for these problems and the authors' resolution are given.

Food marketing on popular children's web sites: a content analysis.  

PubMed

In 2006 the Institute of Medicine (IOM) concluded that food marketing was a contributor to childhood obesity in the United States. One recommendation of the IOM committee was for research on newer marketing venues, such as Internet Web sites. The purpose of this cross-sectional study was to answer the IOM's call by examining food marketing on popular children's Web sites. Ten Web sites were selected based on market research conducted by KidSay, which identified favorite sites of children aged 8 to 11 years during February 2005. Using a standardized coding form, these sites were examined page by page for the existence, type, and features of food marketing. Web sites were compared using chi2 analyses. Although food marketing was not pervasive on the majority of the sites, seven of the 10 Web sites contained food marketing. The products marketed were primarily candy, cereal, quick serve restaurants, and snacks. Candystand.com, a food product site, contained a significantly greater amount of food marketing than the other popular children's Web sites. Because the foods marketed to children are not consistent with a healthful diet, nutrition professionals should consider joining advocacy groups to pressure industry to reduce online food marketing directed at youth.

Data Access and Web Services at the EarthScope Plate Boundary Observatory  

NASA Astrophysics Data System (ADS)

The EarthScope Plate Boundary Observatory (PBO) at UNAVCO, Inc., part of the NSF-funded EarthScope project, is designed to study the three-dimensional strain field resulting from deformation across the active boundary zone between the Pacific and North American plates in the western United States. To meet these goals, PBO will install 880 continuous GPS stations, 103 borehole strainmeter stations, and five laser strainmeters, as well as manage data for 209 previously existing continuous GPS stations and one previously existing laser strainmeter. UNAVCO provides access to data products from these stations, as well as general information about the PBO project, via the PBO web site (http://pboweb.unavco.org). GPS and strainmeter data products can be found using a variety of access methods, incuding map searches, text searches, and station specific data retrieval. In addition, the PBO construction status is available via multiple mapping interfaces, including custom web based map widgets and Google Earth. Additional construction details can be accessed from PBO operational pages and station specific home pages. The current state of health for the PBO network is available with the statistical snap-shot, full map interfaces, tabular web based reports, and automatic data mining and alerts. UNAVCO is currently working to enhance the community access to this information by developing a web service framework for the discovery of data products, interfacing with operational engineers, and exposing data services to third party participants. In addition, UNAVCO, through the PBO project, provides advanced data management and monitoring systems for use by the community in operating geodetic networks in the United States and beyond. We will demonstrate these systems during the AGU meeting, and we welcome inquiries from the community at any time.

Web Based Access to Real-Time Meteorological Products Optimized for PDA- Smartphones  

NASA Astrophysics Data System (ADS)

Recent advances in wireless broadband services and coverage have made access to the internet possible in remote locations. Users can now access the web via an ever increasing number of small, handheld devices specifically designed to allow voice and data exchange using this expanding service. So called PDA phones or smartphones blend the features of traditional PDA devices with telecommunications capabilities. The University of Wisconsin - Madison, Space Science and Engineering Center (SSEC) has produced a web site holding a variety of meteorological image and text displays optimized for this new technology. The site features animations of real-time radar and satellite clouds with value added graphical overlays of severe watches and warnings. Products focus on remotely sensed information supplemented with conventional ground observations. The PDA Animated Weather (PAW) website has rapidly been adopted by numerous institutions and individuals desiring access to real-time meteorological information independent of their location. Of particular note are users that can be classified as first responders, including foreign and domestic based police and file departments. This paper offers an overview of the PAW project including product design, automated production and web presentation. Numerous examples of user applications will be presented, planned future products and functionality will be discussed.

The accessibility of computer-based health information for patients: kiosks and the web.  

PubMed

The Internet is a rich source of health information but it is not as accessible as many claim. This paper brings together three projects to illustrate technical and cost barriers and some options to overcome them. (1) A survey amongst a representative sample of 180 patients in rural Spain showed a marked age gradient in computer access. None over the age of 50 had, and less than 10% planned, access to the Internet whereas a quarter were prepared to use health centre based touchscreen kiosks. (2) Half the commonly used search engines did not include the two most relevant websites for Glasgow colorectal cancer patients in the first ten documents listed, showing the difficulty facing patients in finding relevant information. Selection of information would help patients avoid being overwhelmed with information. (3) One method to improve accessibility is to download websites to kiosks but two projects showed that considerable work is required to reformat the information. Public access computing, such as kiosks, could help make the Internet more accessible. We discuss whether Web sites which structure their information according to method of access, place and person provide a way forward. PMID:11604970

Social Semantic Web at Work: Annotating and Grouping Social Media Content  

NASA Astrophysics Data System (ADS)

Common social tagging systems like Flickr, Delicious and others lately became very popular. The key benefits of these systems include that users can easily annotate Web content and benefit from the annotations of other users with improved retrieval support. With GroupMe! we extend the idea of current social tagging systems by enabling users to not only tag Web resources they are interested in, but also to create collections (groups) of these Web resources by simple drag & drop operations. The grouping metaphor is intuitive and easy for the users, and our evaluation shows that users appreciate the grouping facility, and use this feature to organize and structure diverse Web content. Technically, the grouping of resources carries valuable information about Web resources and their relations. GroupMe! exploits such information to improve search and retrieval. The RESTful Semantic Web interface of GroupMe! enables also other applications to benefit from the GroupMe! features and makes GroupMe! a Social Semantic Web application.

World Wide Web Based Image Search Engine Using Text and Image Content Features  

NASA Astrophysics Data System (ADS)

Using both text and image content features, a hybrid image retrieval system for Word Wide Web is developed in this paper. We first use a text-based image meta-search engine to retrieve images from the Web based on the text information on the image host pages to provide an initial image set. Because of the high-speed and low cost nature of the text-based approach, we can easily retrieve a broad coverage of images with a high recall rate and a relatively low precision. An image content based ordering is then performed on the initial image set. All the images are clustered into different folders based on the image content features. In addition, the images can be re-ranked by the content features according to the user feedback. Such a design makes it truly practical to use both text and image content for image retrieval over the Internet. Experimental results confirm the efficiency of the system.

Content-based image retrieval in the World Wide Web: a web agent for fetching portraits  

NASA Astrophysics Data System (ADS)

This article propose a way to automatically retrieve images from the world-wide-web using a semantic description for images and an agent concept for the retrieval of images. The system represents image in a textual way, e.g. look for a portrait of the a specific person, or fetch an image showing a countryside in Southern California. This textual descriptions are fed in search machines, e.g. yahoo, alta- vista. The resulting html documents are seeked for links. The next step subsequently processes each link by fetching the document other the net, converting it to an ascii representation, and performing a full text search by using the image description. This leads to starting points of images which are retrieved via a web-agent. The image descriptions are decomposed in a set of parts containing image operations which are further processed, e.g. a set for representing the background of a portrait tries to find a homogeneous region in the image because this is likely to find in a portrait. Additional operations are performed on the foreground, i.e. the image region which contains e.g. the face of a person. The system is realized using two C++ libraries: one for building up web-agents, LIWA++, and one for processing images, HORUS.

Like traditional media, information on the World Wide Web may encourage both healthy and unhealthy behaviors. This study reports on the content analysis of a particular genre of Web site that promotes unhealthy behaviors: pro-eating disorder Web sites. Framed in message design theory, the results of this study indicate that messages on pro-eating disorder Web sites promote response efficacy in continuing disordered behaviors, but messages promoting severity and susceptibility to weight gain and self-efficacy were not common. Given the importance of combining response and self-efficacy messages for maximal effectiveness of messages, the pro-eating disorder sites may have limited effectiveness in effecting behavioral change among site visitors.

The WURM project - a web-based freely accessible database of computed physical properties for minerals  

NASA Astrophysics Data System (ADS)

This project aims to build a freely accessible web-based database of computed physical properties for minerals. The database provides for each mineral various physical properties: the crystal structure used in the calculation, the dynamical charges and the dielectric tensors, the refractive index, the Raman spectra with both peak position and intensity and the infrared spectra with peak position. Additional information comprises the parameters of the calculation, to ensure reproducibility of the results. The vibrational information makes the bulk of the database and constitutes the major computational effort. For each vibrational mode in the zone-center we determine the frequency, the symmetry assignment, the atomic displacement patterns, and the Raman tensors. The Raman spectra are represented in both single crystal and powder with different possible laser polarizations. For the infrared modes we give both the TO and the LO components. The database is freely available on the web at http://www.wurm.info and is highly interactive. Jmol-powered applets incorporated in the website allow the quick visualization of the crystal structure and of the atomic displacement patters of all vibrational modes. Further developments include development of a virtual microscope on top of the computed refractive indexes and the analysis of the elastic properties based on the computed elastic constants tensor. All the results are exclusively obtained from first-principles calculations performed using the local density approximation of density functional theory and density functional perturbation theory in the ABINIT implementation [http://www.abinit.org], based on planewaves and pseudopotentials.

The Live Access Server - A Web-Services Framework for Earth Science Data  

NASA Astrophysics Data System (ADS)

The Live Access Server (LAS) is a general purpose Web-server for delivering services related to geo-science data sets. Data providers can use the LAS architecture to build custom Web interfaces to their scientific data. Users and client programs can then access the LAS site to search the provider's on-line data holdings, make plots of data, create sub-sets in a variety of formats, compare data sets and perform analysis on the data. The Live Access server software has continued to evolve by expanding the types of data (in-situ observations and curvilinear grids) it can serve and by taking advantages of advances in software infrastructure both in the earth sciences community (THREDDS, the GrADS Data Server, the Anagram framework and Java netCDF 2.2) and in the Web community (Java Servlet and the Apache Jakarta frameworks). This presentation will explore the continued evolution of the LAS architecture towards a complete Web-services-based framework. Additionally, we will discuss the redesign and modernization of some of the support tools available to LAS installers. Soon after the initial implementation, the LAS architecture was redesigned to separate the components that are responsible for the user interaction (the User Interface Server) from the components that are responsible for interacting with the data and producing the output requested by the user (the Product Server). During this redesign, we changed the implementation of the User Interface Server from CGI and JavaScript to the Java Servlet specification using Apache Jakarta Velocity backed by a database store for holding the user interface widget components. The User Interface server is now quite flexible and highly configurable because we modernized the components used for the implementation. Meanwhile, the implementation of the Product Server has remained a Perl CGI-based system. Clearly, the time has come to modernize this part of the LAS architecture. Before undertaking such a modernization it is important to understand what we hope to gain. Specifically we would like to make it even easier to add new output products into our core system based on the Ferret analysis and visualization package. By carefully factoring the tasks needed to create a product we will be able to create new products simply by adding a description of the product into the configuration and by writing the Ferret script needed to create the product. No code will need to be added to the Product Server to bring the new product on-line. The new architecture should be faster at extracting and processing configuration information needed to address each request. Finally, the new Product Server architecture should make it even easier to pass specialized configuration information to the Product Server to deal with unanticipated special data structures or processing requirements.

Setting Access Permission through Transitive Relationship in Web-based Social Networks  

NASA Astrophysics Data System (ADS)

The rising popularity of various social networking websites has created a huge problem on Internet privacy. Although it is easy to post photos, comments, opinions on some events, etc. on the Web, some of these data (such as a person’s location at a particular time, criticisms of a politician, etc.) are private and should not be accessed by unauthorized users. Although social networks facilitate sharing, the fear of sending sensitive data to a third party without knowledge or permission of the data owners discourages people from taking full advantage of some social networking applications. We exploit the existing relationships on social networks and build a ‘‘trust network’’ with transitive relationship to allow controlled data sharing so that the privacy and preferences of data owners are respected. The trust network linking private data owners, private data requesters, and intermediary users is a directed weighted graph. The permission value for each private data requester can be automatically assigned in this network based on the transitive relationship. Experiments were conducted to confirm the feasibility of constructing the trust network from existing social networks, and to assess the validity of permission value assignments in the query process. Since the data owners only need to define the access rights of their closest contacts once, this privacy scheme can make private data sharing easily manageable by social network participants.

A dialogue-based web application enhances personalized access to healthcare professionals - an intervention study  

PubMed Central

Background In today’s short stay hospital settings the contact time for patients is reduced. However, it seems to be more important for the patients that the healthcare professionals are easy to get in contact with during the whole course of treatment, and to have the opportunity to exchange information, as a basis for obtaining individualized information and support. Therefore, the aim was to explore the ability of a dialogue-based application to contribute to accessibility of the healthcare professionals and exchangeability of information. Method An application for online written and asynchronous contacts was developed, implemented in clinical practice, and evaluated. The qualitative effect of the online contact was explored using a Web-based survey comprised of open-ended questions. Results Patients valued the online contacts and experienced feelings of partnership in dialogue, in a flexible and calm environment, which supported their ability to be active partners and feelings of freedom and security. Conclusion The online asynchronous written environment can contribute to accessibility and exchangeability, and add new possibilities for dialogues from which the patients can benefit. The individualized information obtained via online contact empowers the patients. The Internet-based contacts are a way to differentiate and expand the possibilities for contacts outside the few scheduled face-to-face hospital contacts.

An Easily Accessible Web-Based Minimization Random Allocation System for Clinical Trials  

PubMed Central

Background Minimization as an adaptive allocation technique has been recommended in the literature for use in randomized clinical trials. However, it remains uncommonly used due in part to a lack of easily accessible implementation tools. Objective To provide clinical trialists with a robust, flexible, and readily accessible tool for implementing covariate-adaptive biased-coin randomization. Methods We developed a Web-based random allocation system, MinimRan, that applies Pocock–Simon (for trials with 2 or more arms) and 2-way (currently limited to 2-arm trials) minimization methods for trials using only categorical prognostic factors or the symmetric Kullback–Leibler divergence minimization method for trials (currently limited to 2-arm trials) using continuous prognostic factors with or without categorical factors, in covariate-adaptive biased-coin randomization. Results In this paper, we describe the system’s essential statistical and computer programming features and provide as an example the randomization results generated by it in a recently completed trial. The system can be used in single- and double-blind trials as well as single-center and multicenter trials. Conclusions We expect the system to facilitate the translation of the 3 validated random allocation methods into broad, efficient clinical research practice.

Centralized content-based Web filtering and blocking: how far can it go?  

Microsoft Academic Search

To an organisation, centralized Internet filtering and blocking is very important. Educators and parents would like to block offensive materials from children. Companies also want to reduce the amount of work time that employees spend on non-productive Web surfing. Current blocking and filtering mechanisms can roughly be classified into two approaches: URL-based and content filtering. In the URL-based approach, a

Global Location-Based Access to Web Applications Using Atom-Based Automatic Update  

NASA Astrophysics Data System (ADS)

We propose an architecture which enables people to enquire about information available in directory services by voice using regular phones. We implement a Virtual User Agent (VUA) which mediates between the human user and a business directory service. The system enables the user to search for the nearest clinic, gas station by price, motel by price, food / coffee, banks/ATM etc. and fix an appointment, or automatically establish a call between the user and the business party if the user prefers. The user also has an option to receive appointment confirmation by phone, SMS, or e-mail. The VUA is accessible by a toll free DID (Direct Inward Dialing) number using a phone by anyone, anywhere, anytime. We use the Euclidean formula for distance measurement. Since, shorter geodesic distances (on the Earth’s surface) correspond to shorter Euclidean distances (measured by a straight line through the Earth). Our proposed architecture uses Atom XML syndication format protocol for data integration, VoiceXML for creating the voice user interface (VUI) and CCXML for controlling the call components. We also provide an efficient algorithm for parsing Atom feeds which provide data to the system. Moreover, we describe a cost-effective way for providing global access to the VUA based on Asterisk (an open source IP-PBX). We also provide some information on how our system can be integrated with GPS for locating the user coordinates and therefore efficiently and spontaneously enhancing the system response. Additionally, the system has a mechanism for validating the phone numbers in its database, and it updates the number and other information such as daily price of gas, motel etc. automatically using an Atom-based feed. Currently, the commercial directory services (Example 411) do not have facilities to update the listing in the database automatically, so that why callers most of the times get out-of-date phone numbers or other information. Our system can be integrated very easily with an existing web infrastructure, thereby making the wealth of Web information easily available to the user by phone. This kind of system can be deployed as an extension to 911 and 411 services to share the workload with human operators. This paper presents all the underlying principles, architecture, features, and an example of the real world deployment of our proposed system. The source code and documentations are available for commercial productions.

World Wide Web Access to Radiation Datasets for Environmental and Climate Change Studies.  

NASA Astrophysics Data System (ADS)

Five years of scanner data from the Earth Radiation Budget Experiment (ERBE), eight years of surface radiation budget (SRB) data, and one year of scanner radiation budget data from the French-Russian-German experiment, ScaRaB, will be available for use by colleges and universities [and primary and secondary (K-12) schools] over a World Wide Web browser. The database for ERBE is a 5-yr monthly average time series from February 1985 through December 1989, and ScaRaB is a 1-yr dataset from February 1994 to March 1995. ERBE and ScaRaB include shortwave radiative fluxes, emitted longwave radiative fluxes, and the earth's albedo measured at the top of the atmosphere. The SRB dataset spans the period from July 1983 through June 1991 and includes surface downward shortwave fluxes, surface downward longwave fluxes, surface albedos, and cloud percent. Students will have access to the data in three ways. They can display general image format images of any month and visually observe month-to-month or interannual variations. The data files for each month also have a spreadsheet format and can be downloaded in their entirety into any spreadsheet application program for further analysis. Third, using a live access server (LAS), students can interact directly with the data to select and subset datasets in terms of month, year, latitude, and longitude. The LAS allows students to view images of subsetted regions, and to subset data values to a file for further analysis. The server for this dataset is located at the National Aeronautics and Space Administration Langley Research Center, Hampton, Virginia.

Enhancing Access to and Use of NASA Satellite Data through OGC Web Services for the Hydrologic Community  

NASA Astrophysics Data System (ADS)

In order to facilitate the remote access to geographically distributed hydrologic data sources and tools, the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) is developing standards- based, Open Geospatial Consortium (OGC) Web Services, e.g., Web Map Service (WMS) and Web Coverage Service (WCS) for selected data sets that it archives. These services, which give alternative ways to acquire and explore remotely sensed data, offer a practical, cost-effective solution for integrating information distributed among user systems. Spatial-temporal data queries are sent directly to the OGC-compliant servers, the requested Web Services are triggered, and the output data are directly served back to the clients on the fly. GES DISC OGC Web Services can be easily integrated into any OGC-compliant clients such as Google Earth, NASA WorldWind, NASA Earth-Sun System Gateway(ESG), which combines satellite imagery and maps in a Geographic Information System (GIS) environment. OGC clients allow users to access and explore data residing on different Web Mapping Servers distributed throughout the Internet. Current data sets served at the GES DISC through its WMS (as rendered maps or images) include Tropical Rainfall Measuring Mission (TRMM) Gridded Rainfall (Near Real Time, V6) and Atmospheric Infrared Sounder (AIRS) Brightness Temperature. The latter is also served through the WCS (as original Hierarchical Data Format or HDF data). WMS and WCS can be easily extended to serve other GES DISC data sets of interest to the hydrologic community, to enhance the access to NASA satellite data.

Cable modem access to picture archiving and communication system images using a web browser over the Internet.  

PubMed

This presentation describes our experiences using a web-based viewing software and a browser to view our picture archiving and communication system (PACS) images at a remote site with cable modem-internet communications. Our testing shows that using a cable modem to access our radiology webserver produces acceptable transmission speeds to remote sites. The average time-to-display (TTD) for 16 computed tomography (CT) images on the web-based intranet system in our hospital was 7 to 8 seconds. Using a cable modem and comparable equipment at a remote site, the average TTD is 16 seconds over the internet. The TTD does not significantly change during various hours of the day. Security for our hospital-based PACS is provided by a firewall. Access through the firewall is accomplished using virtual private network (VPN) software, a secure ID, and encryption. We have found that this is a viable method for after-hours subspecialty radiology consultation. PMID:10847372

Providing location-independent access to patient clinical narratives using Web browsers and a tiered server approach.  

PubMed Central

Health care today depends upon timely access to patient medical data and the latest medical knowledge. As we make the transition from a hospital-based organization to an integrated health care delivery system, patient care information must move throughout the organization quickly and efficiently over increasing distances. The emergence of widely-dispersed referral networks demands novel solutions to the problems of delivering patient care information to providers. We have developed a mechanism to provide location-independent access to clinical narrative reports using a multi-tiered server model and World Wide Web technologies for delivery. To successfully deploy such a system to sites separated by large distances, it is important to reduce complexity at the client site. Using a "thin client", such as a web browser, in our design facilitates deployment and support while reducing cost per user. This architecture allows the application to be updated without modification to the end-user software and eases maintenance over long distances.

Mars 101: Linking Educational Content to Mission Purpose on the Phoenix Mars Lander Mission Web Site  

NASA Astrophysics Data System (ADS)

The Phoenix Mars Lander, scheduled to launch in August 2007, is the first mission in NASA's Scout Program. Phoenix has been specifically designed to measure volatiles (especially water) in the northern arctic plains of Mars, where the Mars Odyssey detected evidence of ice-rich soil near the surface. A fundamental part of the mission's goal-driven education and public outreach program is the Phoenix Mars Lander 2007 web site. Content for the site was designed not only to further the casual user's understanding of the Phoenix mission and its objectives, but also to meet the needs of the more science-attentive user who desires in-depth information. To this end, the web site's "Mars 101" module includes five distinct themes, all of which are directly connected to the mission's purpose: Mars Intro includes basic facts about Mars and how the planet differs from Earth; Polar Regions discusses the history of polar exploration on Earth and the similarities between these regions on Mars and Earth; Climate covers the effects that Earth's polar regions have on climate and how these same effects may occur on Mars; Water on Mars introduces the reader to the idea of liquid water and water ice on Mars; and Biology includes a discussion of the requirements of life and life in the universe to facilitate reader understanding of what Phoenix might find. Each of the five themes is described in simple language accompanied by relevant images and graphics, with hypertext links connecting the science-attentive user to more in-depth content. By presenting the "Mars 101" content in a manner that relates each subheading to a specific component of the mission's purpose, the Phoenix web site nurtures understanding of the mission and its relevance to NASA's Mars Exploration goals by the general lay public as well as the science-attentive user.

Web Service Access and Display of USGS Oceanographic Time-Series Data Using the NOAA Earth Research Division's Data Access Program (ERDDAP)  

NASA Astrophysics Data System (ADS)

The sediment transport group of the U.S. Geologic Survey Coastal Marine Geology Program (USGS CMGP) maintains an archive of more than 4400 NetCDF files collected over the last 30 years (Montgomery et al, 2007). The conventions used in these NetCDF files were determined long before the emerging standard Climate and Forecast (CF) conventions for NetCDF, and web access has been traditionally been limited to simple downloading of the NetCDF files. To take advantage of a growing suite of software that works with CF-compliant data, A combination of NcML and the THREDDS Data Server were used to allow web services access of CF compliant data via the OGC WCS service and OPeNDAP. The primary users of these coastal oceanographic measurements are modelers who are facile with netCDF files and URL references. Other users, however, may prefer to obtain the data in another format or perhaps just plot a variable. To assist both groups of users, we have evaluated NOAA's Earth Research Division's Data Access Program (ERDDAP) as a potential method of providing a more flexible and powerful interface to the data. This versatile program is able to access data from a variety of web services, including OPeNDAP, and then deliver the data using web services in a very wide variety of formats, from common image formats such as PNG and JPG (pictures of plots), to NetCDF, Matlab, text and spreadsheet formats. Installation and configuration of ERDDAP was straightforward. The software written in Java, and delivered as a War file that runs on a standard Tomcat server. Configuration of the user interface and the dataset list is controlled by XML files. The documentation is well written and much of the XML generation is handled by the supplied autogen function that reads a netCDF file and generates XML based on the file attributes. We are working on a Matlab program that will completely automate the process by interrogating our data holdings and producing the completely formed XML. Our initial assessment is that the ERDDAP server does indeed enable a more versatile way for users to interact with our data. Allowing users to select specific variables, time ranges and plot or data formats is a huge improvement.

Usage of data-encoded web maps with client side color rendering for combined data access, visualization, and modeling purposes  

NASA Astrophysics Data System (ADS)

Current approaches to satellite observation data storage and distribution implement separate visualization and data access methodologies which often leads to the need in time consuming data ordering and coding for applications requiring both visual representation as well as data handling and modeling capabilities. We describe an approach we implemented for a data-encoded web map service based on storing numerical data within server map tiles and subsequent client side data manipulation and map color rendering. The approach relies on storing data using the lossless compression Portable Network Graphics (PNG) image data format which is natively supported by web-browsers allowing on-the-fly browser rendering and modification of the map tiles. The method is easy to implement using existing software libraries and has the advantage of easy client side map color modifications, as well as spatial subsetting with physical parameter range filtering. This method is demonstrated for the ASTER-GDEM elevation model and selected MODIS data products and represents an alternative to the currently used storage and data access methods. One additional benefit includes providing multiple levels of averaging due to the need in generating map tiles at varying resolutions for various map magnification levels. We suggest that such merged data and mapping approach may be a viable alternative to existing static storage and data access methods for a wide array of combined simulation, data access and visualization purposes.

Transcriptome Tomography for Brain Analysis in the Web-Accessible Anatomical Space  

PubMed Central

Increased information on the encoded mammalian genome is expected to facilitate an integrated understanding of complex anatomical structure and function based on the knowledge of gene products. Determination of gene expression-anatomy associations is crucial for this understanding. To elicit the association in the three-dimensional (3D) space, we introduce a novel technique for comprehensive mapping of endogenous gene expression into a web-accessible standard space: Transcriptome Tomography. The technique is based on conjugation of sequential tissue-block sectioning, all fractions of which are used for molecular measurements of gene expression densities, and the block- face imaging, which are used for 3D reconstruction of the fractions. To generate a 3D map, tissues are serially sectioned in each of three orthogonal planes and the expression density data are mapped using a tomographic technique. This rapid and unbiased mapping technique using a relatively small number of original data points allows researchers to create their own expression maps in the broad anatomical context of the space. In the first instance we generated a dataset of 36,000 maps, reconstructed from data of 61 fractions measured with microarray, covering the whole mouse brain (ViBrism: http://vibrism.riken.jp/3dviewer/ex/index.html) in one month. After computational estimation of the mapping accuracy we validated the dataset against existing data with respect to the expression location and density. To demonstrate the relevance of the framework, we showed disease related expression of Huntington’s disease gene and Bdnf. Our tomographic approach is applicable to analysis of any biological molecules derived from frozen tissues, organs and whole embryos, and the maps are spatially isotropic and well suited to the analysis in the standard space (e.g. Waxholm Space for brain-atlas databases). This will facilitate research creating and using open-standards for a molecular-based understanding of complex structures; and will contribute to new insights into a broad range of biological and medical questions.

Magnetic Fields for All: The GPIPS Community Web-Access Portal  

NASA Astrophysics Data System (ADS)

The new GPIPS website portal provides community users with an intuitive and powerful interface to query the data products of the Galactic Plane Infrared Polarization Survey. The website, which was built using PHP for the front end and MySQL for the database back end, allows users to issue queries based on galactic or equatorial coordinates, GPIPS-specific identifiers, polarization information, magnitude information, and several other attributes. The returns are presented in HTML tables, with the added option of either downloading or being emailed an ASCII file including the same or more information from the database. Other functionalities of the website include providing details of the status of the Survey (which fields have been observed or are planned to be observed), techniques involved in data collection and analysis, and descriptions of the database contents and names. For this initial launch of the website, users may access the GPIPS polarization point source catalog and the deep coadd photometric point source catalog. Future planned developments include a graphics-based method for querying the database, as well as tools to combine neighboring GPIPS images into larger image files for both polarimetry and photometry.

The NASA Ames PAH IR Spectroscopic Database: A Demo of its Contents and Web Tools  

NASA Astrophysics Data System (ADS)

The features formerly known as the Unidentified Infrared (UIR) Emission Bands are now generally attributed to polycyclic aromatic hydrocarbons (PAHs). Exploitation of these features as astrophysical and astrochemical probes requires the IR properties of PAHs under interstellar conditions. To fulfill this need, we experimentally measured and theoretically computed the 2-2000 µm spectra of many PAHs over the past 18 years at NASA's Ames Research Center. Today's collection comprises about 600 theoretically computed and 60 laboratory measured spectra of PAHs in different forms. The molecules in the collection range in size from C10H8 to C130H28. For most of these, spectra are available for PAHs in their neutral and singly charged (+/-) states. In some cases, IR spectra of multiply charged species were also computed. The database includes pure PAHs; PAHs containing nitrogen (PANHs), oxygen, and silicon; PAHs with side groups; PAHs with extra hydrogens; and PAHs complexed with iron and magnesium. This collection of PAH spectra from 2 - 2000 µm has been assembled into a uniform database, which we will make publicly available on the web in early 2009. A WebGUI interface has been developed that can effectively interrogate the database using a variety of queries, such as formula, molecular name, charge, specific number of atoms, etc. Several molecules can be selected in such a process and one can obtain their 3-D structures, plot and co-add their spectra, adjust parameters such as the bandwidth, download their data and print graphs. The database can also be downloaded as a whole and IDL-routines are provided to interrogate it. This talk will present an overview of the contents and the web-GUI tools of the NASA Ames PAH IR Spectroscopic Database. Hands-on demonstrations will be available at the SOFIA Booth.

The objective of this descriptive study was to analyze the accessibility and the content of the information about Specialization Courses in Nursing Administration available on the websites of federal universities in Brazil. From September 2008 to April 2009, evaluations were performed on a total 19 courses that were available on the websites of the universities, regarding the level of access to information and the design of the curricula, in terms of the structure of the knowledge about Nursing Administration: Ideological and Theoretical Bases, Intervention Methods, and Resource Administration Practices. Results showed that, though we are currently in the era of the knowledge society, the electronic access to the teaching programs remain below the expectations in terms of the concepts of information and browsability. In terms of the design of the courses, it was observed that most are many times longer than the what s legally established as a minimum load of hours, and that there has been an appreciation towards studying the Ideological and Theoretical Bases in detriment to the Practices of Human Resources.

Integrated Web-Based Access to and use of Satellite Remote Sensing Data for Improved Decision Making in Hydrologic Applications  

NASA Astrophysics Data System (ADS)

Using NASA satellite remote sensing data from multiple sources for hydrologic applications can be a daunting task and requires a detailed understanding of the data's internal structure and physical implementation. Gaining this understanding and applying it to data reduction is a time-consuming task that must be undertaken before the core investigation can begin. In order to facilitate such investigations, the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) has developed the GES-DISC Interactive Online Visualization ANd aNalysis Infrastructure or "Giovanni," which supports a family of Web interfaces (instances) that allow users to perform interactive visualization and analysis online without downloading any data. Two such Giovanni instances are particularly relevant to hydrologic applications: the Tropical Rainfall Measuring Mission (TRMM) Online Visualization and Analysis System (TOVAS) and the Agricultural Online Visualization and Analysis System (AOVAS), both highly popular and widely used for a variety of applications, including those related to several NASA Applications of National Priority, such as Agricultural Efficiency, Disaster Management, Ecological Forecasting, Homeland Security, and Public Health. Dynamic, context- sensitive Web services provided by TOVAS and AOVAS enable users to seamlessly access NASA data from within, and deeply integrate the data into, their local client environments. One example is between TOVAS and Florida International University's TerraFly, a Web-enabled system that serves a broad segment of the research and applications community, by facilitating access to various textual, remotely sensed, and vector data. Another example is between AOVAS and the U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS)'s Crop Explorer, the primary decision support tool used by FAS to monitor the production, supply, and demand of agricultural commodities worldwide. AOVAS is also part of GES DISC's Agricultural Information System (AIS), which can operationally provide satellite remote sensing data products (e.g., near- real-time rainfall) and analysis services to agricultural users. AIS enables the remote, interoperable access to distributed data, by using the GrADS-Data Server (GDS) and the Open Geospatial Consortium (OGC)- compliant MapServer. The latter allows the access of AIS data from any OGC-compliant client, such as the Earth-Sun System Gateway (ESG) or Google Earth. The Giovanni system is evolving towards a Service- Oriented Architecture and is highly customizable (e.g., adding new products or services), thus availing the hydrologic applications user community of Giovanni's simple-to-use and powerful capabilities to improve decision-making.

NASA Astrophysics Data System (ADS)

The US Geoscience information network has developed metadata profiles for interoperable catalog services based on ISO19139 and the OGC CSW 2.0.2. Currently data services are being deployed for the US Dept. of Energy-funded National Geothermal Data System. These services utilize OGC Web Map Services, Web Feature Services, and THREDDS-served NetCDF for gridded datasets. Services and underlying datasets (along with a wide variety of other information and non information resources are registered in the catalog system. Metadata for registration is produced by various workflows, including harvest from OGC capabilities documents, Drupal-based web applications, transformation from tabular compilations. Catalog search is implemented using the ESRI Geoportal open-source server. We are pursuing various client applications to demonstrated discovery and utilization of the data services. Currently operational applications allow catalog search and data acquisition from map services in an ESRI ArcMap extension, a catalog browse and search application built on openlayers and Django. We are developing use cases and requirements for other applications to utilize geothermal data services for resource exploration and evaluation.

Installing computers in older adults' homes and teaching them to access a patient education web site: a systematic approach.  

PubMed

This article describes the experiences of nurses who, as part of a large clinical trial, brought the Internet into older adults' homes by installing a computer, if needed, and connecting to a patient education Web site. Most of these patients had not previously used the Internet and were taught even basic computer skills when necessary. Because of increasing use of the Internet in patient education, assessment, and home monitoring, nurses in various roles currently connect with patients to monitor their progress, teach about medications, and answer questions about appointments and treatments. Thus, nurses find themselves playing the role of technology managers for patients with home-based Internet connections. This article provides step-by-step procedures for computer installation and training in the form of protocols, checklists, and patient user guides. By following these procedures, nurses can install computers, arrange Internet access, teach and connect to their patients, and prepare themselves to install future generations of technological devices.

Meeting clinician information needs by integrating access to the medical record and knowledge resources via the Web.  

PubMed Central

MINDscape is a web based integrated interface to diverse sources of clinical information including both patient specific information (electronic medical record) as well as medical knowledge (the "digital library") to provide "just in time" information at the point of care. It was developed at the University of Washington to meet clinical information needs both as identified locally and by a review of the literature. Beta testing by over 600 clinicians is in progress and medical centers wide access scheduled for Fall 1997. We describe the information needs we sought to meet and the ongoing evaluation approach we are taking to ensure the information needs of a diverse group of clinicians are met. The iterative evolution of the interface from prototype, to alpha to large scale beta testing is reported. Integration of information occurs at three levels: integration of information by patient, integration of information by provider, and integration of patient specific information with medical reference material and decision support tools.

A dynamic, web-accessible resource to process raw microarray scan data into consolidated gene expression values: importance of replication  

PubMed Central

We propose a freely accessible web-based pipeline, which processes raw microarray scan data to obtain experimentally consolidated gene expression values. The tool MADSCAN, which stands for MicroArray Data Suites of Computed ANalysis, makes a practical choice among the numerous methods available for filtering, normalizing and scaling of raw microarray expression data in a dynamic and automatic way. Different statistical methods have been adapted to extract reliable information from replicate gene spots as well as from replicate microarrays for each biological situation under study. A carefully constructed experimental design thus allows to detect outlying expression values and to identify statistically significant expression values, together with a list of quality controls with proposed threshold values. The integrated processing procedure described here, based on multiple measurements per gene, is decisive for reliably monitoring subtle gene expression changes typical for most biological events.

Kinome Render: a stand-alone and web-accessible tool to annotate the human protein kinome tree  

PubMed Central

Human protein kinases play fundamental roles mediating the majority of signal transduction pathways in eukaryotic cells as well as a multitude of other processes involved in metabolism, cell-cycle regulation, cellular shape, motility, differentiation and apoptosis. The human protein kinome contains 518 members. Most studies that focus on the human kinome require, at some point, the visualization of large amounts of data. The visualization of such data within the framework of a phylogenetic tree may help identify key relationships between different protein kinases in view of their evolutionary distance and the information used to annotate the kinome tree. For example, studies that focus on the promiscuity of kinase inhibitors can benefit from the annotations to depict binding affinities across kinase groups. Images involving the mapping of information into the kinome tree are common. However, producing such figures manually can be a long arduous process prone to errors. To circumvent this issue, we have developed a web-based tool called Kinome Render (KR) that produces customized annotations on the human kinome tree. KR allows the creation and automatic overlay of customizable text or shape-based annotations of different sizes and colors on the human kinome tree. The web interface can be accessed at: http://bcb.med.usherbrooke.ca/kinomerender. A stand-alone version is also available and can be run locally.

An International Comparison of Web-based Reporting About Health Care Quality: Content Analysis  

PubMed Central

Background On more and more websites, consumers are provided with public reports about health care. This move toward provision of more comparative information has resulted in different information types being published that often contain contradictory information. Objective The objective was to assess the current state of the art in the presentation of online comparative health care information and to compare how the integration of different information types is dealt with on websites. The content analysis was performed in order to provide website managers and Internet researchers with a resource of knowledge about presentation formats being applied internationally. Methods A Web search was used to identify websites that contained comparative health care information. The websites were systematically examined to assess how three different types of information (provider characteristics and services, performance indicators, and health care user experience) were presented to consumers. Furthermore, a short survey was disseminated to the reviewed websites to assess how the presentation formats were selected. Results We reviewed 42 websites from the following countries: Australia, Canada, Denmark, Germany, Ireland, the Netherlands, Norway, the United Kingdom, the United States, and Sweden. We found the most common ways to integrate different information types were the two extreme options: no integration at all (on 36% of the websites) and high levels of integration in single tables on 41% of the websites). Nearly 70% of the websites offered drill down paths to more detailed information. Diverse presentation approaches were used to display comparative health care information on the Internet. Numbers were used on the majority of websites (88%) to display comparative information. Conclusions Currently, approaches to the presentation of comparative health care information do not seem to be systematically selected. It seems important, however, that website managers become aware of the complexities inherent in comparative information when they release information on the Web. Important complexities to pay attention to are the use of numbers, the display of contradictory information, and the extent of variation among attributes and attribute levels. As for the integration of different information types, it remains unclear which presentation approaches are preferable. Our study provides a good starting point for Internet research to further address the question of how different types of information can be more effectively presented to consumers.

Frontier: High Performance Database Access Using Standard Web Components in a Scalable Multi-Tier Architecture  

SciTech Connect

A high performance system has been assembled using standard web components to deliver database information to a large number of broadly distributed clients. The CDF Experiment at Fermilab is establishing processing centers around the world imposing a high demand on their database repository. For delivering read-only data, such as calibrations, trigger information, and run conditions data, we have abstracted the interface that clients use to retrieve data objects. A middle tier is deployed that translates client requests into database specific queries and returns the data to the client as XML datagrams. The database connection management, request translation, and data encoding are accomplished in servlets running under Tomcat. Squid Proxy caching layers are deployed near the Tomcat servers, as well as close to the clients, to significantly reduce the load on the database and provide a scalable deployment model. Details the system's construction and use are presented, including its architecture, design, interfaces, administration, performance measurements, and deployment plan.

Providing access to risk prediction tools via the HL7 XML-formatted risk web service.  

PubMed

Cancer risk prediction tools provide valuable information to clinicians but remain computationally challenging. Many clinics find that CaGene or HughesRiskApps fit their needs for easy- and ready-to-use software to obtain cancer risks; however, these resources may not fit all clinics' needs. The HughesRiskApps Group and BayesMendel Lab therefore developed a web service, called "Risk Service", which may be integrated into any client software to quickly obtain standardized and up-to-date risk predictions for BayesMendel tools (BRCAPRO, MMRpro, PancPRO, and MelaPRO), the Tyrer-Cuzick IBIS Breast Cancer Risk Evaluation Tool, and the Colorectal Cancer Risk Assessment Tool. Software clients that can convert their local structured data into the HL7 XML-formatted family and clinical patient history (Pedigree model) may integrate with the Risk Service. The Risk Service uses Apache Tomcat and Apache Axis2 technologies to provide an all Java web service. The software client sends HL7 XML information containing anonymized family and clinical history to a Dana-Farber Cancer Institute (DFCI) server, where it is parsed, interpreted, and processed by multiple risk tools. The Risk Service then formats the results into an HL7 style message and returns the risk predictions to the originating software client. Upon consent, users may allow DFCI to maintain the data for future research. The Risk Service implementation is exemplified through HughesRiskApps. The Risk Service broadens the availability of valuable, up-to-date cancer risk tools and allows clinics and researchers to integrate risk prediction tools into their own software interface designed for their needs. Each software package can collect risk data using its own interface, and display the results using its own interface, while using a central, up-to-date risk calculator. This allows users to choose from multiple interfaces while always getting the latest risk calculations. Consenting users contribute their data for future research, thus building a rich multicenter resource. PMID:23793601

The KUPKB: a novel Web application to access multiomics data on kidney disease.  

PubMed

The information gathered from the large number of omics experiments in renal biology is underexplored, as it is scattered over many publications or held in supplemental data. To address this, we have developed an open-source Kidney and Urinary Pathway Knowledge Base (KUPKB) that facilitates simple exploration of these omics data. The KUPKB currently comprises 220 data sets (miRNA, mRNA, proteins, and metabolites) extracted from existing publications or databases. Researchers can explore the integrated data using the iKUP browser, and a simple template is provided to submit new omics data sets to the knowledge base. As an example of iKUP's use, we show how we identified, in silico, calreticulin as a protein induced in human interstitial fibrosis and tubular atrophy (IFTA) in chronic kidney transplant rejection; a link that would have been difficult to establish using existing Web-based tools. Using immunohistochemistry, we validated in vivo this in silico result in human and rat biopsies of IFTA, thus identifying calreticulin as a potential new player in chronic kidney transplant rejection. The KUPKB provides a simple tool that enables users to quickly survey a wide range of omics data sets and has been shown to facilitate rapid hypothesis generation in the context of renal pathophysiology.

Are Personal Health Records Safe? A Review of Free Web-Accessible Personal Health Record Privacy Policies  

PubMed Central

Background Several obstacles prevent the adoption and use of personal health record (PHR) systems, including users’ concerns regarding the privacy and security of their personal health information. Objective To analyze the privacy and security characteristics of PHR privacy policies. It is hoped that identification of the strengths and weaknesses of the PHR systems will be useful for PHR users, health care professionals, decision makers, and designers. Methods We conducted a systematic review using the principal databases related to health and computer science to discover the Web-based and free PHR systems mentioned in published articles. The privacy policy of each PHR system selected was reviewed to extract its main privacy and security characteristics. Results The search of databases and the myPHR website provided a total of 52 PHR systems, of which 24 met our inclusion criteria. Of these, 17 (71%) allowed users to manage their data and to control access to their health care information. Only 9 (38%) PHR systems permitted users to check who had accessed their data. The majority of PHR systems used information related to the users’ accesses to monitor and analyze system use, 12 (50%) of them aggregated user information to publish trends, and 20 (83%) used diverse types of security measures. Finally, 15 (63%) PHR systems were based on regulations or principles such as the US Health Insurance Portability and Accountability Act (HIPAA) and the Health on the Net Foundation Code of Conduct (HONcode). Conclusions Most privacy policies of PHR systems do not provide an in-depth description of the security measures that they use. Moreover, compliance with standards and regulations in PHR systems is still low.

Supporting Access to Antarctic Scientific Data - Antarctic Master Directory content and usage continues to increase  

NASA Astrophysics Data System (ADS)

The Antarctic Master Directory (AMD) has been accumulating data set descriptions for more than ten years. Recent statistics document the success of this international effort: content of the AMD (measured as the number of data set descriptions, by their country of origin), and usage (measured as the number of AMD searches and data set description retrievals, by country of origin) show marked and sustained increases. A related ongoing effort to involve all of the countries with Antarctic field research programs is also proving to be successful, with more and more countries contributing data set descriptions to the AMD. The results to date indicate that the AMD is becoming more and more useful to scientists, educators and policy makers. It provides an easy to use, flexible yet consistent, no-cost discovery tool to find out what data have been collected, by whom, how, and in many cases, provide direct access through links to online data repositories. The AMD is also an easy way for scientists to promote recognition of their work amongst the scientific community, thereby fostering interaction, potential collaboration and future funding opportunities. This paper describes the AMD, how to use it and how to contribute to it. The international organizational framework and relevance to current and planned Antarctic initiatives are also described.

Automating Information Discovery Within the Invisible Web  

NASA Astrophysics Data System (ADS)

A Web crawler or spider crawls through the Web looking for pages to index, and when it locates a new page it passes the page on to an indexer. The indexer identifies links, keywords, and other content and stores these within its database. This database is searched by entering keywords through an interface and suitable Web pages are returned in a results page in the form of hyperlinks accompanied by short descriptions. The Web, however, is increasingly moving away from being a collection of documents to a multidimensional repository for sounds, images, audio, and other formats. This is leading to a situation where certain parts of the Web are invisible or hidden. The term known as the "Deep Web" has emerged to refer to the mass of information that can be accessed via the Web but cannot be indexed by conventional search engines. The concept of the Deep Web makes searches quite complex for search engines. Google states that the claim that conventional search engines cannot find such documents as PDFs, Word, PowerPoint, Excel, or any non-HTML page is not fully accurate and steps have been taken to address this problem by implementing procedures to search items such as academic publications, news, blogs, videos, books, and real-time information. However, Google still only provides access to a fraction of the Deep Web. This chapter explores the Deep Web and the current tools available in accessing it.

WebMIRS: web-based medical information retrieval system  

NASA Astrophysics Data System (ADS)

At the Lister Hill National Center for Biomedical Communications, a research and development division of the National Library of Medicine (NLM), we are developing a prototype multimedia database system to provide World Wide Web access to biomedical databases. WebMIRS (Web-based Medical Information Retrieval System) will allow access to databases containing text and images and will allow database query by standard SQL, by image content, or by a combination of the two. The system is being developed in the form of Java applets, which will communicate with the Informix DBMS on an NLM Sun workstation running the Solaris operating system. The system architecture will allow access from any hardware platform, which supports a Java-enabled Web browser, such as Netscape or Internet Explorer. Initial databases will include data from two national health surveys conducted by the National Center for Health Statistics (NCHS), and will include x-ray images from those surveys. In addition to describing in- house research in database access systems, this paper describes ongoing work toward querying by image content. Image content search capability will include capability to search for x-ray images similar to an input image with respect to vertebral morphometry used to characterize features such as fractures and disc space narrowing.

Evaluation of a Web Portal for Improving Public Access to Evidence-Based Health Information and Health Literacy Skills: A Pragmatic Trial  

PubMed Central

Background Using the conceptual framework of shared decision-making and evidence-based practice, a web portal was developed to serve as a generic (non disease-specific) tailored intervention to improve the lay public's health literacy skills. Objective To evaluate the effects of the web portal compared to no intervention in a real-life setting. Methods A pragmatic randomised controlled parallel trial using simple randomisation of 96 parents who had children aged <4 years. Parents were allocated to receive either access to the portal or no intervention, and assigned three tasks to perform over a three-week period. These included a searching task, a critical appraisal task, and reporting on perceptions about participation. Data were collected from March through June 2011. Results Use of the web portal was found to improve attitudes towards searching for health information. This variable was identified as the most important predictor of intention to search in both samples. Participants considered the web portal to have good usability, usefulness, and credibility. The intervention group showed slight increases in the use of evidence-based information, critical appraisal skills, and participation compared to the group receiving no intervention, but these differences were not statistically significant. Conclusion Despite the fact that the study was underpowered, we found that the web portal may have a positive effect on attitudes towards searching for health information. Furthermore, participants considered the web portal to be a relevant tool. It is important to continue experimenting with web-based resources in order to increase user participation in health care decision-making. Trial Registration ClinicalTrials.gov NCT01266798

This invention relates to computer implemented methods and systems for content mobilization, and in particular, methods and systems for mobilization of video, music, photos and other media, including processes for mobile search, mobile messaging, building a mobile content library, and combinations thereof. Content mobilization may be initiated by entry of search parameters or keywords and followed by retrieval of search results (e.g. videos, images, audio files) from online source(s). Upon selection of a content item by user, the process dynamically retrieves the media from online source. Further, the media file may be dynamically edited and then dynamically transcoded and sent to a mobile device.

Construction of web-based nutrition education contents and searching engine for usage of healthy menu of children.  

PubMed

A diet habit, which is developed in childhood, lasts for a life time. In this sense, nutrition education and early exposure to healthy menus in childhood is important. Children these days have easy access to the internet. Thus, a web-based nutrition education program for children is an effective tool for nutrition education of children. This site provides the material of the nutrition education for children with characters which are personified nutrients. The 151 menus are stored in the site together with video script of the cooking process. The menus are classified by the criteria based on age, menu type and the ethnic origin of the menu. The site provides a search function. There are three kinds of search conditions which are key words, menu type and "between" expression of nutrients such as calorie and other nutrients. The site is developed with the operating system Windows 2003 Server, the web server ZEUS 5, development language JSP, and database management system Oracle 10 g. PMID:20126375

Nutrition content of food and beverage products on Web sites popular with children.  

PubMed

We assessed the nutritional quality of branded food and beverage products advertised on 28 Web sites popular with children. Of the 77 advertised products for which nutritional information was available, 49 met Institute of Medicine criteria for foods to avoid, 23 met criteria for foods to neither avoid nor encourage, and 5 met criteria for foods to encourage. There is a need for further research on the nature and extent of food and beverage advertising online to aid policymakers as they assess the impact of this marketing on children. PMID:19443816

Data extraction from web pages based on structural-semantic entropy  

Microsoft Academic Search

Most of today's web content is designed for human consumption, which makes it difficult for software tools to access them readily. Even web content that is automatically generated from back-end databases is usually presented without the original structural information. In this paper, we present an automated information extraction algorithm that can extract the relevant attribute-value pairs from product descriptions across

Facilitating access to laboratory guidelines by modeling their contents and designing a computerized user interface.  

PubMed

Laboratory tests are not always prescribed appropriately. Guidelines for some important laboratory tests have been developed by expert panels in the Parisian region to maximize the appropriateness of laboratory medicine. However; these recommendations are not frequently consulted by physicians and nurses. We developed a system facilitating consultation of these guidelines, to increase their usability. Elements of information contained in these documents were identified and included in recommendations of different categories. UML modeling was used to represent these categories and their relationships to each other in the guidelines. We used the generated model to implement a computerized interface. The prototype interface, based on web-based technology was found to be rapid and easy to use. By clicking on provided keywords, information about the subject sought is highlighted whilst retaining the entire text of the guideline on-screen. PMID:21893797

The EarthScope Array Network Facility: application-driven low-latency web-based tools for accessing high-resolution multi-channel waveform data  

NASA Astrophysics Data System (ADS)

Since April 2004 the EarthScope USArray seismic network has grown to over 400 broadband stations that stream multi-channel data in near real-time to the Array Network Facility in San Diego. Providing secure, yet open, access to real-time and archived data for a broad range of audiences is best served by a series of platform agnostic low-latency web-based applications. We present a framework of tools that interface between the world wide web and Boulder Real Time Technologies Antelope Environmental Monitoring System data acquisition and archival software. These tools provide audiences ranging from network operators and geoscience researchers, to funding agencies and the general public, with comprehensive information about the experiment. This ranges from network-wide to station-specific metadata, state-of-health metrics, event detection rates, archival data and dynamic report generation over a stations two year life span. Leveraging open source web-site development frameworks for both the server side (Perl, Python and PHP) and client-side (Flickr, Google Maps/Earth and jQuery) facilitates the development of a robust extensible architecture that can be tailored on a per-user basis, with rapid prototyping and development that adheres to web-standards.
