Construction of Fuzzy OWL Ontologies Using Fuzzy Relational Databases
Classical OWL ontologies can not directly represent and process fuzzy knowledge that is widespread in many Semantic Web applications.Considering the advantage of fuzzy relational databases in the representation and management of fuzzy data,construction of fuzzy ontologies by making use of fuzzy relational databases is proposed.The RDF data types are fuzzy extended and the OWL is extended from the aspect of fuzzy data types,which can solve the problem of representing fuzzy OWL ontologies.On this basis,a method of constructing fuzzy OWL ontologies using fuzzy relational databases as data source is studied,which provides an efficient solution to the construction of fuzzy ontologies in the Semantic Web.
