Abstract: A relational database-based approach to store the fuzzy OWL 2 ontologies on the semantic Web was proposed. The structural and semantic characteristics of fuzzy OWL 2 ontologies were analyzed, and according to the fuzzy relational databases, storage architecture for the fuzzy OWL 2 ontologies were introduced, based on which, a formal mapping approach from the fuzzy OWL 2 ontologies to the fuzzy relational databases was presented. The results showed that the proposed formal mapping approach is rational and feasible.

Key words: fuzzy set, fuzzy OWL 2 ontologies, fuzzy relational databases, mapping, transforming
