基于本体的故障诊断知识库系统的构建

Modeling of failure Diagnose Knowledge Base System based on Ontology

传统故障诊断技术采用专家系统的知识库是封闭的或半封闭的,其知识库的构造和知识的输入与修改均需由设计者来进行,不能从故障诊断的成功经验中提取相关的知识。本体作为知识的基本元素,可以进行知识类比推理,抽象出事物内在的本质,适合于描述知识库的内部单元。提出一种基于本体的故障诊断知识库系统模型,并依据该模型设计了故障诊断专家系统。

Because of the knowledge base based on the expert system of traditional failure diagnose technique is close or half close,to construct its knowledge base and to input or to modify the knowledge all need by the designer,so it can＇t pick up related knowledge from successful experience of failure diagnose.So this article try to advanced a method of building failure diagnose knowledge base system based on ontology according to the ＇ontology＇ which apply more wide in the knowledge engineering and the related application realm in recently years,The knowledge base system part of this method adopt to the ontology method,so researching it is this article＇s emphases.
