Abstract:
This study evaluates the retrieval effectiveness of the technical report database of the Defense RDTE On-Line System when a free text generated index file is used instead of uncontrolled vocabulary. The study found that free text searching provides a viable alternative to the use of uncontrolled vocabulary, and that it can prove to be a valuable tool in any information retrieval system.
