Science.gov is a gateway to over 50 million pages of authoritative selected science information provided by U.S. government agencies, including research and development results
In February 2007, the Science.gov Alliance launched version 4.0, which allowed even further refinement of search queries. For the first time, patrons could search within their original results. In addition, the relevancy ranking algorithms became more sophisticated, providing ranking of the entire full text of documents on sites where searchable full text resides. Date of the document was priority-weighted for ranking purposes. A new feature allows patrons to share search results via e-mail with colleagues and friends.
Science.gov 4.0 employs technology to enable distributed nodes to operate in a grid computing paradigm to facilitate a rapid analysis of full text. Grid technology would allow improved relevancy ranking of search results.
A number of participating agencies are members of CENDI, which provides administrative support and coordination for science.gov. These agencies are committed to serving the information needs of the science-attentive citizen, including science professionals, students and teachers, and the business community. The Alliance and science.gov were formed in response to the April 2001 workshop, "Strengthening the Public Information Infrastructure for Science."
