摘要
描述逻辑是本体的基础,在实际应用中,描述逻辑可被扩展.介绍了描述逻辑的一种新的扩展——带比较表达式的模糊描述逻辑(FCDLs)来表示和推理语义网的模糊知识.FCDLs的语法和语义以及公理和断言也有明确的定义.FCDLs是模糊描述逻辑(FDLs)的模糊概念和扩展的模糊描述逻辑(EFDLs)的剪集概念的结合.FCDLs和FDLs一样,它也可以使用语义网上的模糊知识来表示、推理模糊本体.
Description logics is the basis of the ontologies.In practice,description logics can be extended.Introduced the fuzzy description logics with comparison（FCDLs）as a new fuzzy extension of description logics to representing and reasoning for the expressive fuzzy knowledge on the semantic web.The definition of the syntax and semantics in the fuzzy description logics with comparison（FCDLs）will be specified,and the axioms and assertions will be described.FCDLs is composed by the conception of fuzzy description logics（FDLs）and the cut of the extended fuzzy description logics.So,FCDLs liked FDLs can use the fuzzy knowledge to representing and reasoning the ontologies.
