Classification Clustering, Probabilistic Information Retrieval, and the Online Catalog.
Larson, Ray R.
Library Quarterly, v61 n2 p133-73 Apr 1991
Discusses problems with subject searches in online library catalogs and examines theoretical principles for the design of effective information retrieval systems. Probabilistic ranking methods are discussed, and an experimental online catalog called CHESHIRE is described. It is noted that CHESHIRE uses classification clustering, provides natural language searching, and prevents the retrieval of too much material. (95 references) (LRW)
