摘要: 随着计算机和Internet的快速发展,语义网和描述逻辑在人工智能等领域扮演着越来越重要的角色。但在日常生活中,越来越多不确定的、不完整的知识需要解决,而现存的OWL只能表述确定的完整的概念和关系。为了能够表示和推理模糊知识,给出了一个基于描述逻辑SHIQ的全新的模糊描述逻辑公理体系——F-SHIQ公理体系,并以此公理体系为基础,扩展了OWL本体语言,能够描述和推理模糊知识。该文首先给出了系统详细的定义、公理、定理以及定理的证明;然后详述了如何用FSRL,即基于F-SHIQ的OWL扩展,来表示和推理模糊信息;最后通过一个例子来检验扩展语言的应用效果。

Abstract: With the swift development of computer and Internet,semantic Web and description logics play more and more important roles in intelligent technologies.But in our lives,more and more uncertain and incomplete knowledge needs to be resolved,and the vocabularies supplied by OWL only represent certain and complete concepts and roles.In order to be able to represent and reason with fuzzy information,this paper presents a new fuzzy description logic axiom system—F-SHIQ axiom system based on the description logic.And based on this axiom system,the authors extend OWL by combining new style of F-SHIQ axiom system.This paper first presents the definitions,axioms,theorems and proofs in the system,and then details the ways to represent and reason fuzzy information by FSRL—the extension of OWL by F-SHIQ.Finally,illustrate a fuzzy inference question in extended language and obtain a satisfactory result.
