摘要 语义网需要能够以一种智能的方式来表示和处理模糊知识与数据信息,但最近的研究证明,OWL在数据类型表示方面存在严重的局限性:首先,它不能处理在语义网和本体中广泛存在的不精确以及不确定信息;其次,它不支持自定义数据类型及自定义数据类型谓词的表示。为了解决上述局限性,提出了一种新的模糊描述逻辑F-SHOIN(G),给出了F-SHOIN(G)的语法、语义。然后,以F-SHOIN(G)为逻辑基础,并结合RDF/XML的语法规范,重新编码OWL中的描述算子,用来表示模糊本体知识,形成f-OWL。f-OWL不仅能够表示本体中的模糊知识,而且能够表示本体中含有自定义模糊数据类型及自定义模糊数据类型谓词的模糊数据信息,为模糊本体的研究提供了新的表示方法。最后,还给出了由OWL文件到f-OWL文件的转换规则,从而实现了f-OWL对OWL的兼容。 The Semantic Web is expected to process fuzzy concept knowledge and data type information in an intelligent and automatic way.Recent research has shown that OWL has some serious limitations:i.e.,it can't process imprecise and uncertain information which widely exists in the Semantic Web and ontology;furthermore,it does not support customized data types and customized data type predicates.In this paper,we made the following two contributions to solve the above limitations:(i) presented a new kind of fuzzy description logic F-SHOIN(G),and gave its syntax and semantics;(ii) extended OWL to f-OWL by recoding the description norms of OWL,based on F-SHOIN(G) and the syntax specification of RDF/XML.f-OWL can not only support the representation of fuzzy concept knowledge,but also fuzzy data information with customized fuzzy data types and customized fuzzy data type predicates.It provides a new representation method for the investigation of ontology.
