基于知识网格在整合知识资源方面的优势,分析了知识网格环境下客户协同产品创新知识共享的特征,提出了知识共享模型,并对其关键研究点进行了深入研究。通过提出“创意一问题一功能”模型实现创新主体非结构化创意知识的转化;创建产品创新知识共享概念本体并定义其上下位关系;在对知识共享概念本体按概念型、规则型和实例型划分的基础上,提出一种基于OWL的产品创新知识本体语义表示方法;建立了知识共享的访问机制和原型系统,并通过某型号手持电钻的产品创新设计验证了所提出模型与原型系统的有效性和可行性。
The features of customer collaborative product innovation knowledge sharing on knowl- edge grid were analyzed, a knowledge sharing model was put forward and its correlated key points were deeply researched. An "innovation--problem--function" model was presented to realize the non --structure creativity transformation; then an ontology concept of product innovation knowledge sha- ring and its top--bellow relation was established and defined. And the ontology concept was divided according to concept type, rule type and instances type, on the basis of this the means of product in- novation knowledge ontology semantic based on OWL were propounded. Finally, the access mecha- nism and prototype system of knowledge sharing was constructed, and the feasibility and validity were testified by the product innovation design of an electric drill.
