An Analytic Measure Predicting Information Retrieval System Performance.

Losee, Robert M.

Information Processing and Management, v27 n1 p1-13 1991

Provides a method for estimating precision without examining individual database documents, which requires knowledge of only the query or expressed information need and a set of database parameters constant for all queries. Concepts of historic and expected precision are examined, and applications of precision-document graphs are assessed. (36 references) (Author/SD)
