The objective of this paper is to present the first results concerning the mapping and implementation of the Fuzzy Semantic Model (FSM) as a Fuzzy Object-Relational database Model (FuzzORM). This solution permits to take advantages of both relational and object-oriented databases. The object-relational database management system PostgreSQL has been used for the implementation of the FuzzORM.
The use of ontologies in the Semantic Web allows for semantic query answering. The problem of answering queries in term of ontologies defined using Description Logic formalisms suffers from high worst-case complexity. The problem becomes more complex with fuzzy ontologies as fuzzy DLs should allow human-like expression and approximate reasoning. Many approaches for query rewriting have been proposed...
The Semantic Web is an infrastructure that enables the interchange, the integration and the reasoning about information on the Web. In the Semantic Web, the resources are described using particular metadata called “Semantic annotations”. A semantic annotation is a particular case of annotation which refers to ontology. The Web content is, for the most part, subject to uncertainty or imperfection....
