基于中介逻辑的带有三种否定的RDF扩展

摘要

Medium logic is a kind of logic system that distinguishes contradictory negation from opposite negation, and confirms the existence of medium objects between opposite concepts. This paper, based on the extension of RDF by medium logic, proposes an RDF extension, called ERDF, that contains contradictory negation, opposite negation and medium negation. The role of ERDF in semantic web search engines is discussed too. It is proven that it is more powerful on knowledge expression than RDF. ERDF can improve the completeness and precision with search engines based on semantic web.%中介逻辑是一种区分矛盾否定与对立否定、肯定一些对立概念间存在中介对象的逻辑系统.基于中介逻辑对RDF(Resource Description Framework)进行扩展,从而提出一种带有矛盾否定、对立否定和中介否定的RDF的扩展ERDF(Extension ofResource Description Framework),并且讨论了ERDF在语义Web搜索引擎中的作用.表明比RDF具有更强的知识表达能力,ERDF能够提高基于语义Web的搜索引擎的查全率和查准率.
