基于语言变量的模糊本体模型

he fuzzy ontology with fuzzy concepts is an extension of the domain ontology with crisp concepts for solving the uncertainty problems. Present fuzzy ontology models do not focus on essential semantic relationships between fuzzy concepts, which lead difficulty in ontology mapping and integrating. To represent formally the fuzzy linguistic variables which is the basic of fuzzy knowledge, this paper proposes a new kind of fuzzy ontology models, considering semantic relationships of concepts: set relation, order relation and equivalence relation. Application of the fuzzy ontology to transportation knowledge modeling shows that this research facilitates the knowledge share and reuse for fuzzy systems on semantic web.
