摘　　要：用Jena[11]建立的本体中概念及其关系都是确定的,但是,现实世界中事物及其关系往往具有模糊性且这种模糊性会随着事物的发展而变化。为了将Web上资源及其关系的模糊性表示出来,在RDF[9]的三元组(主体、谓词、客体)中的谓词部分加入一个表示谓词的模糊性的权值,提出一个新的概念—模糊资源描述框架(FRDF,Fuzzy Resource Descrip-tion Framework),FRDF用三元组(主体、(谓词、权值)、客体)来描述Web上的资源及其关系。那么本体的建立工具Jena就要进行相应的扩充与修改以适应模糊本体的建立。研究语义网及模糊资源描述框架FRDF[1]理论的基础上,着重讨论了模糊本体的形式化[5]描述,模糊jena的定义,建立模糊jena。The concepts and their relationships which established with Jena in ontology are identified,but the real world things and their relationships often have the fuzziness and this ambiguity will change as the development of things.In order to express the resources and their relational fuzziness in the web,one weight that expresses ambiguity of the predicate was joined in the predicate part of the RDF triple and proposed a new concept—FRDF.The resources and their relationships in web were described by triple（subject,（predicate,weight）,object） in FRDF.Therefore,the ontology establishment tool Jena needs to make the appropriate expansion and change to accommodate the establishment of fuzzy ontology.Basing on the study of the semantic net and FRDF theory,this article focuses on the formal description of the fuzzy ontology,the definition and the establishment of fuzzy jana.
