Abstract

This paper deals with database preference queries involving fuzzy conditions which do not explicitly refer to an attribute from the database, but whose meaning is rather inferred from a set of fuzzy rules. The approach we propose, which is based on the fuzzy inference pattern called generalized modus ponens, significantly increases the expressivity of fuzzy query languages inasmuch as it allows for new types of predicates. An implementation strategy involving a coupling between a DBMS and an inference engine is outlined.
