扩展OWL处理模糊知识

Extending OWL by Vocabularies of Fuzzy Description Logic

摘要: 为了解决模糊Ontology的表示和推理问题,本文结合网络本体语言OWL的特点,在模糊描述逻辑的基础上,构建了RDF/XML式的模糊算子和公理.用来表达Ontology中的模糊概念和模糊声明;提出了OWL到模糊算子的转换规则,统一了模糊Ontology中确定知识的表示方法.最后,利用新增模糊词汇和转换规则解决了视频提取领域的模糊知识表示和推理任务.

Abstract: In order to represent fuzzy Ontology,this paper extends existing Ontology Web Language(OWL), which can only represent certain and complete concepts and knowledge at present,by encoding fuzzy constructors,axioms constraints and maps semantics of new vocabularies to fuzzy description logic.Moreover,the paper presents mapping rules from OWL to new vocabularies named fuzzy Ontology Web Language(FOWL). At last,the paper gives an example of image retrieval to show representation and reasons of fuzzy Ontology in FOWL form.
