Science.gov's search goes deeper

The government repository for science information, Science.gov, has been updated with a new feature that allows for deep document searching.DeepRank is an algorithm that allows full-text analysis of documents and records. The process is more accurate than conventional searches, but takes more time because it is resource intensive.Originally launched in December 2002 by 16 government science organizations and 12 federal agencies, Science.gov contains more than 50 million pages of information from almost all fields of science. The Web site calls itself the “USA.gov for science.”The search portal was last updated to Version 3.0 in 2005, when it introduced MetaRank, a function that allows users to rank their search results through metadata such as subjects, titles and keywords.Other new features in Science.gov 4.0 include the abilities to search within results, sort results and e-mail them.Agencies involved in the Science.gov project include Agriculture, Commerce, Defense, Education, Energy, Health and Human Services, and Interior departments; the Environmental Protection Agency; the Government Printing Office; the National Science Foundation; the National Archives and Records Administration; and NASA.
