基于本体的机械产品知识仓库研究与应用

为解决产品开发全生命周期中知识管理与知识重用问题，提出了基于本体的机械产品知识仓库系统构架。从语法、属性、结构、实例四个方面进行相似性的计算，实现将源本体的实例映射到目标本体的过程。采用OWL本体表示语言对产品知识进行本体建模。并对基于本体的案例推理进行了深入的研究。最后将研究成果应用于制造业知识管理系统的机械产品知识仓库子系统中。

The Study of Knowledge Base of Machine Product Based on Ontology

In order to solve the problem of knowledge management and knowledge reuse in the whole lifecycle of products development, a kind of framework of knowledge base of machine product based on ontology is put forward. The similarity is accounted in the four respects of syntax, attribute, structure and instance. So the process of mapping source ontology to object ontology is realized. The product knowledge model is built by using the ontology express language OWL (Web Ontology Language) and the method of case-based reasoning based on ontology is deeply studied too. At last, these methods are applied in the machine products knowledge base subsystem, which belongs to the knowledge management system of manufacturing.
