摘要

描述逻辑知识库由TBox和ABox两部分组成。Tableau算法主要用于dl知识推理中的一致性测试,它基于二值逻辑,无法实现多值概念的一致性测试。本文将基本理念引入到dl系统中,通过定义粗糙概念的蕴涵度来改进Tableau算法,并利用粗糙概念在TBbox中表达相关概念和关系,完成对粗糙概念的推理的粗糙描述逻辑,为知识库推理引擎的设计奠定基础。

Knowledge reasoning and Tableau Algorithm improving based on rough description logics
The knowledge base of description logics are composed of two parts TBox and ABox. Tableau Algorithm is for the uniformity testing in the knowledge reasoning of DLs, which is based on two-value logics, it can not realize the uniformity testing for multiple-valued concepts. This paper take the fundamental ideal to the system of DLs, improving Tableau Algorithm through the definition of rough concept implication degree, and by using rough concept express related concepts and relationships in the TBbox, The rough description logics can be completed on the reasoning of rough concept, laying the foundation for knowledge base inference engine design.
