A Comparison of Two Methods for Indexing and Retrieval from a Full-Text Medical Database.
Hersh, William R.; Hickman, David H.
Proceedings of the ASIS Annual Meeting, v29 p221-30 1992
Describes a study that compared two information retrieval systems on a full-text medical database: one featured concept-based automatic indexing and statistical retrieval techniques, and the second used traditional word-based Boolean techniques. Evaluation of search results by calculating relative recall and precision is discussed, and user preferences are examined. (20 references) (LRW)
