In this paper, we propose a formal model of fuzzy ontology with property hierarchy by combining theories in cognitive psychology and fuzzy set theory. A formal mechanism used to determine object memberships in concepts is also proposed. In this mechanism, object membership is based on the defining properties of concepts and properties which objects possess. We show that our model is more reasonable in calculating object memberships and more powerful in concept representation than previous models by an example.
