Augmenting Approximate Similarity Searching with Lexical Information
2005-01-01

Accurately representing synonymy using distributional similarity requires large volumes of data to reliably represent infrequent words. However, the na�ve nearest-neighbour approach to compare context vectors extracted from large corpora scales poorly. The Spatial Approximation Sample Hierarchy (SASH) is a data-structure for performing approximate ...

A threshold-improved narrow-width approximation for BSM physics
2008-04-01

A modified narrow-width approximation that allows for Script O(?/M)-accurate predictions for resonant particle decay with similar intermediate masses is proposed and applied to MSSM processes to demonstrate its importance for searches for particle physics beyond the Standard Model.

Approximate Searching for Distributional Similarity
2005-01-01

Distributional similarity requires large volumes of data to accurately represent infrequent words. However, the nearestneighbour approach to finding synonyms suffers from poor scalability. The Spatial Approximation Sample Hierarchy (SASH), proposed by Houle (2003b), is a data structure for approximate nearestneighbour queries that balances the ...

Finding protein and nucleotide similarities with FASTA.
2004-02-01

The FASTA package provides a comprehensive set of similarity searching programs, similar to those provided by the BLAST package, and some additional programs that are not provided by BLAST for searching with short peptides and oligonucleotides. The FASTA programs work with a wide variety of database formats, ...

Application of kernel functions for accurate similarity search in large chemical databases
2010-04-29

BackgroundSimilaritysearch in chemical structure databases is an important problem with many applications in chemical genomics, drug design, and efficient chemical probe screening among others. It is widely believed that structure based methods provide an efficient way to do the query. Recently various graph kernel functions have been designed to capture the intrinsic ...

Protein structural similarity search by Ramachandran codes
2007-08-23

BackgroundProtein structural data has increased exponentially, such that fast and accurate tools are necessary to access structure similarity search. To improve the search speed, several methods have been designed to reduce three-dimensional protein structures to one-dimensional text strings that are then analyzed ...

Structural search and retrieval using a tableau representation of protein folding patterns.
2008-01-05

Comparison and classification of folding patterns from a database of protein structures is crucial to understand the principles of protein architecture, evolution and function. Current search methods for proteins with similar folding patterns are slow and computationally intensive. The sharp growth in the number of known protein structures poses severe ...

The cost of search for multiple targets: effects of practice and target similarity.
2009-06-01

With the use of X-ray images, performance in the simultaneous search for two target categories was compared with performance in two independent searches, one for each category. In all cases, displays contained one target at most. Dual-target search, for both categories simultaneously, produced a cost in accuracy, although the magnitude ...

Automatic Content Creation for Games to Train Students Distinguishing Similar Chinese Characters
2009-01-01

In learning Chinese, many students often have the problem of mixing up similar characters. This can cause misunderstanding and miscommunication in daily life. It is thus important for students learning the Chinese language to be able to distinguish similar characters and understand their proper usage. In this paper, we propose a game style framework in ...

Scaling Distributional Similarity to Large Corpora
2006-01-01

Accurately representing synonymy using distributional similarity requires large volumes of data to reliably represent infrequent words. However, the na�ve nearestneighbour approach to comparing context vectors extracted from large corpora scales poorly (O(n 2) in the vocabulary size). In this paper, we compare several existing approaches to approximating ...

Fast and accurate protein substructure searching with simulated annealing and GPUs
2010-09-03

BackgroundSearching a database of protein structures for matches to a query structure, or occurrences of a structural motif, is an important task in structural biology and bioinformatics. While there are many existing methods for structural similarity searching, faster and more accurate approaches are still ...
