An automatic information retrieval system for the scientific and engineering computer program abstracts at Arnold Engineering Development Center

The design of an information retrieval system is presented which is based on the high precision-low recall theory. So as to extend its usefulness, a feedback feature has been incorporated into the design which allows the user to refine the search so as to produce the most relevant (to the user) retrievals. This system has been tested in daily use, and it has proved to be a valuable aid to the scientific and engineering personnel at Arnold Engineering Development Center.
