The data stored in relational databases has fuzzy semantics. For example, “high”, “short”, “fat”, “thin”, “moderate”, “normal” are fuzzy data. The NULL value is the incomplete information stored in relational databases, which also leads to the uncertainty of relational database. Fuzzy ontology is to describe the shared conceptual model of fuzzy concepts and communication between

Ontology can be the basis for knowledge representation and heterogeneous data integration. But manual constructing of ontology is time-consuming and error-prone. And many methods of constructing ontology from relational databases are proposed. The data sources of heterogeneous data integration mainly come from the relational databases. But, the method of constructing ontologies from integrated databases is
