Retrieval testing by the comparison of statistically independent retrieval methods

Author

Abstract

A procedure for retrieval testing is developed which is based on the comparison of statistically independent methods of retrieval applied to the same database. This is, in essence, a form of relative retrieval testing in which, due to the independence assumption, the conclusions drawn may be taken as absolute. The methodology is illustrated on a large database of MEDLINE records where documents are themselves used as queries. Test results in this setting indicate that, among the several methods tested, a form of cosine coefficient retrieval will give the best performance for the purpose of clustering documents or producing nearest neighbors of documents. © 1992 John Wiley & Sons, Inc.
