Title

Fuzzy requests : an approach to weighted Boolean searches

Source

Journal of the American Society for Information Science. 30(1979), S.240-247

Year

1979

Abstract

This article concerns the problem of how to permit a patron tp represent the relatice importance of various index terms in a Boolean request while retaining the desirable properties of a Boolean system. The character of classical Boolean systems is reviewed and related to the notion of fuzzy sets. The fuzzy set concept then forms the basis of the concept of a fuzzy request in which weights are assigned to index terms. The properties of such a system are discussed, and it is shown that such systems retain the manipulability of traditional Boolena requests
