An evaluation of retrieval effectiveness for a full-text document-retrieval system

David C. Blair, M. E. Maron

Abstract

An evaluation of a large, operational full-text document-retrieval system (containing roughly 350,000 pages of text) shows the system to be retrieving less than 20 percent of the documents relevant to a particular search. The findings are discussed in terms of the theory and practice of full-text document retrieval.
