摘要
在研究集成产品开发模式中知识共享和知识重用的基础上,结合本体理论,研究了基于语义的产品设计知识表达,分析了产品设计中知识需求的背景论域和个人轮廓特征,建立了产品设计的知识管理框架,提出了基于反馈的概念关联知识检索方法,并通过对查准率和查全率的对比分析,验证了该研究成果的实用性和有效性。
On the basis of knowledge sharing and knowledge reusing in IPD, the paper used ontology theory to study the expression of product design knowledge base on semantics, to analyze the background of the knowledge demands and personal characteristics, to set up the knowledge management frame of product design, to propose the method of knowledge retrieval on the basis of the concept feedback. Through comparing and analyzing recall ratio and accuracy ratio of knowledge retrieval, the practicability and validity of this research results were verified.
