Formalizing object membership in fuzzy ontology with property importance and property priority

In this paper, we formalize the object membership in fuzzy ontology with property importance and property priority, while previous models lack building blocks to handle the importance and priority of properties. A formal mechanism used to measure object memberships in concepts is proposed. Such a mechanism can measure object memberships in concepts defined by properties with importance or priority well. We show that our model is more reasonable in measuring object memberships in concepts than previous models by examples and experiments.
