Washington, DC –The
latest version of Science.gov was released this week, introducing DeepRank
which allows a more sophisticated level of relevancy ranking when searching
federal science databases and Web sites. Using the full text of documents when
available, DeepRank will help researchers and citizens pinpoint the science
information they need. This technology complements the relevancy ranking capabilities
of MetaRank and QuickRank, which were introduced in earlier versions of Science.gov
and which are still deployed.
Science.gov 4.0 also added a “refine search” feature to narrow
returns within an original set of results; as well as an “email results” feature
so that individuals may opt to e-mail important science information to themselves,
friends and family, or colleagues. Version 4.0 offers more ways to view search
results: By title, author or date, as well as by relevancy rank or source as
in earlier versions.
“Science.gov pulls together the nation’s large and often isolated
Web-based collections of federal scientific information,” said Dr. Raymond
Orbach, U.S. Department of Energy (DOE) Under Secretary of Science. “This
is an important tool for citizens as they seek the everyday science information
they need.”
At Science.gov, a single query can be searched across 30 databases and more
than 1,800 scientific Web sites. Science.gov allows users to search the
surface Web as well as the deep Web, where traditional search engines typically
cannot go. The information is free and no registration is required. Hosted
by the DOE Office of Scientific and Technical Information (OSTI), Science.gov
is the gateway to reliable science and technology information from 16 organizations
within 12 federal science agencies.
The research for DeepRank was performed and the capability deployed by Deep
Web Technologies (DWT), a small business located in Santa Fe, New Mexico. Funding
was provided through a U.S. Department of Energy Phase II Small Business Innovation
Research (SBIR) Program award.
Science.gov is made possible by members of the Science.gov Alliance: the Departments
of Agriculture, Commerce, Defense, Education, Energy, Health and Human Services,
and the Interior, the Environmental Protection Agency, the Government Printing
Office, the National Aeronautics and Space Administration and the National
Science Foundation, with support from the National Archives and Records Administration.
