Publication Date: Origin: AUTHOR Abstract The NASA Astrophysics Data System (ADS), along with astronomy's journals and data centers, has developed a distributed on-line digital library which has become the dominant means by which astronomers search, access and read their technical literature. By combining data from the text, citation, and reference databases with data from the ADS readership logs we have been able to create Second Order Bibliometric Operators, a customizable class of collaborative filters which permits substantially improved accuracy in literature queries. Using the ADS usage logs along with membership statistics from the International Astronomical Union and data on the population and gross domestic product (GDP) we develop an accurate model for world-wide basic research where the number of scientists in a country is proportional to the GDP of that country, and the amount of basic research done by a country is proportional to the number of scientists in that country times that country's per capita GDP. | |
