摘要： 针对从预先定义的概念层次生成模糊本体这一非常困难的问题,提出利用模糊概念模型来构建模糊本体.基于模糊集理论,对UML概念模型及OWL DL本体进行了模糊扩展,从二者的逻辑基础说明了利用模糊UML类图构建模糊OWL DL本体的可行性,进而研究了从模糊UML类图到模糊OWL DL本体的形式化映射方法,给出了映射规则及公理的创建过程.利用现有的模糊概念模型构建模糊OWL DL本体可以有效降低建立模糊本体的复杂性,同时增强了本体的表达能力.

Abstract: Classical ontology supported by formalized concepts is unable to represent the imprecision and uncertainty information. Ontology incorporated with fuzzy logic is a solution to the problem. Considering the difficulty to generate the fuzzy ontology in accordance to pre-defined concepts, framing the fuzzy ontology on the basis of fuzzy conceptual model is proposed. The UML conceptual model and OWL DL ontology are therefore fuzzily extended separately on the basis of fuzzy set theory, and the feasibility of framing the fuzzy OWL DL ontology by fuzzy UML class diagram is interpreted in the perspective of their logical foundation. Then, the formalized mapping transformation of fuzzy UML class diagram into fuzzy OWL DL ontology is studied to show the mapping rules and axiomatization process. Framing the fuzzy OWL DL ontology with existing fuzzy conceptual model can reduce efficiently the complexity of framing the fuzzy ontology and, meanwhile, enhance the expressibility of ontology.
