Deep Web Technologies (Los Alamos, NM) received SBIR funding to research and develop a web-based search tool with relevance-ranking of search results from multiple internet databases.  This new technology sorts through selected databases and rapidly returns information in an order likely to meet the users’ needs.  Soon after its development, this technology was embraced by the U.S. government’s interagency Science.gov Alliance and applied to the interagency portal Science.gov, which makes available to the public reliable information resources selected by the respective agencies as their best science information. Science.gov was developed by an interagency working group of 14 scientific and technical information organizations from 10 major science agencies. Together these agencies make up the Science.gov Alliance. The Alliance and Science.gov were formed to improve and enhance access to information stemming from government R&D programs. 

The version of the government’s portal, which first introduced Deep Web Technologies’ relevance ranking for multiple databases, was named Science.gov 2.0.  Officially launched on May 11, 2004, Science.gov 2.0 introduced relevancy-ranking to the vast stores of government R&D results and searches the 47 million pages of government R&D results and presents the results to the users in relevancy-ranked order.
