— Information in real-world applications is often vague, imprecise and uncertain. Ignoring the inherent imperfect nature of real-world will undoubtedly introduce some deformation of human perception of real-world and may eliminate several substantial information, which may be very useful in several data-intensive applications.

—This paper discusses the mapping of the Fuzzy Semantic Model (FSM) into a Fuzzy Object Relational database Model (FuzzORM). We designed a set of mapping rules to transform all the constructs of the FSM into the FuzzORM. A prototype supporting these rules is under development over the Object-Relational Database Management System (ORDBMS) PostgreSQL. The(More)

Two types of scores are considered, which are computed by respectively selecting the edge with the minimum or the edge with the maximum weight in the matching graph. The(More)
