Combining Fuzzy Description Logics and Fuzzy Logic Programs

Integrating rules and ontologies has become a key requirement for applications in the semantic Web. Web applications in general have also motivated another requirement, that of handling uncertainty, an intrinsic feature of the real world. In this paper, we present a fuzzy extension to description logic programs (DLP), called fhDLP. fhDLP not only combines DL with LP, as in DLP, but also supports uncertainty representation. More specifically, fuzzy hybrid knowledge bases layered on fhDLP consist of fuzzy hybrid rules with embedded DL queries to fuzzy DL concepts, roles, and axioms.
