Science.gov, a search engine for government science information and research results, yesterday released its latest version of Science.gov search engine. Version 4.0 deploys “DeepRank” which allows search and relevancy ranking across full text of documents, when full text is available. In addition, users can now choose a “refine results” option to narrow returns within a search, as well as view search results in multiple ways: by title, author or date, as well as by relevancy rank or source. The search also includes Deep Web search capability of content not accessible by popular search engines.
Science.gov searches authoritative science information from 30 federal scientific databases and more than 1,800 science Web sites. The search 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.
