Fuzzy set theory utility for database and information systems

Abstract

Information systems are often thought of as encompassing database systems as well as information retrieval systems [4]. Fuzzy set theory has had a significant impact in all of these systems. For both areas various fuzzy set representations for imprecise data have been utilized. Additionally fuzzy matching approaches have been applied in database querying and information retrieval. © 2013 Springer-Verlag Berlin Heidelberg.
