Fuzzy Logic and Semantic Web Technologies


Logo

This area of research concerns the study of methods to support different types of uncertainty in Semantic Web technologies. Particularly, we mainly focus on the combination of fuzzy logic with Description Logics or ontologies [1]. This makes it possible to represent imprecise knowledge and to perform approximate reasoning. For example, in a fuzzy ontology there can be a fuzzy concept assertion stating than an individual is partially a member of a class, and we can ask a fuzzy reasoner to retrieve the instances of a class together with their membership degrees. Some results of our research include:
