摘　　要：针对OWL在数据类型表示方面存在严重的局限性,即它不能处理在语义Web和本体中广泛存在的不精确以及不确定信息,也不支持自定义数据类型及自定义数据类型谓词的表示,介绍了一种新的模糊描述逻辑F-ALC(G),给出了F-ALC(G)的语法、语义.然后,以F-ALC(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。The semantic web is expected to process fuzzy-concept knowledge and data-type information in an intelligent and automatic way. Recent researches showed that OWL has strict limitations on some aspects, i. e. , it can＇t process imprecise and uncertain information which is so much in semantic web and its notology, and it does not support the data of self-defining type and the predicates relevant to them. A new fuzzy description logic F-ALC（G） is therefore introduced to break through the limitation, with its web grammar, syntax and semanteme given. Then, taking the F-ALC（ G ） as logical foundation and combining it with the web grammar/syntax norms RDF/XML, the descriptors in OWL are recoded to represent the fuzzy-concept knowledge so as to form f-OWL which is able to represent not only the fuzzy knowledge but also the data of self-defining type and the fuzzy information on the predicates relevant to them. A new representation is thus provided for the investigation on fuzzy notology.
