Science.gov 3.0 – A
More Precise Search
Alliance of 12 federal science agencies launches latest version
DC – The latest version of Science.gov,
launched November 15, allows more refined queries for searches
of federal science databases. While Science.gov 3.0 is available
to everyone, the upgrade will be especially helpful to scientists
and information specialists.
Science.gov 3.0 introduces “MetaRank,” a technology
which uses a sophisticated method for ranking science queries
by searching the “metadata,” or bibliographic information
such as title, author, date, abstract or other keyword identifiers.
This technology complements the relevancy ranking capabilities
of QuickRank, which was introduced in Version 2.0 and is still
deployed on every search.
“We think all citizens searching for science information – especially
those using advanced searches – will appreciate this latest
version of Science.gov,” said Eleanor Frierson, Deputy Director,
National Agricultural Library and co-chair of the Science.gov
Alliance. “We’ve worked hard to implement MetaRank
and other enhancements that help make search results more relevant
Tom Lahr, Deputy Associate Chief Biologist for Information,
U.S. Geological Survey, and co-chair of the Science.gov Alliance,
noted that researchers and information specialists should find
Version 3.0 a step forward in relevancy ranking of government
science information. “MetaRank will return more targeted
results from deep Web databases, making the nation’s research
and development data even more accessible,” said Lahr.
Science.gov 3.0 also offers enhanced Boolean search capabilities,
fielded searching, intuitive site navigation, and early viewing
of results while a search of databases and Web sites continues
in real time.
Science.gov, the nation’s FirstGov for Science, is a gateway
to reliable science and technology information from 17 organizations
within 12 federal science agencies. A single query searches across
more than 1,800 Web sites and 30 databases. Science.gov allows
users to search the surface Web as well as the deep Web, where
traditional search engines generally cannot go. The information
is free and no registration is required.
Deep Web Technologies (DWT), a small business located in Los
Alamos, New Mexico, performed the research for MetaRank, in part
through a competitive grant award for infrastructure research
from the U.S. Department of Energy’s Small Business Innovation
Research (SBIR) Program.
In addition to the SBIR grant, DWT’s efforts to prototype
and implement MetaRank on Science.gov were supported by contributing
members of the Science.gov Alliance: The Departments of Agriculture,
Defense, Energy, Health and Human Services, and the Interior,
the Environmental Protection Agency, and the Government Printing
Other science agencies participating in the Science.gov Alliance
are the Departments of Commerce and Education, the National Aeronautics
and Space Administration, and the National Science Foundation,
with support from the National Archives and Records Administration.
Science.gov is hosted by DOE’s Office of Scientific and
