摘　　要：利用特征检索产品是一种基于知识的检索方法 .这种检索方法要求有相应的知识库 .然而 ,如何从计算机可理解的语义和量化特征两方面描述知识模型是建立产品知识库的一个关键 .文中提出了一种产品功能特征的描述方法 ,它以用户的客观评价为依据 ,并实现产品特征的量化描述 .利用属性理论建立产品对象和查询要求的综合描述方法 ,在网络环境中建立一种基于产品特征的检索系统 。Retrieving the information of products by product features is a knowledge based process, being supported by knowledge base. However, expressing knowledge by computer understandable semantics and quantifying product features are the key parts of a knowledge base. A method to describe the quantified functional characteristics of product based on customer's criteria is developed. A comprehensive description of product and query requirements by attribute theory is worked out. Finally, a system that searches designing knowledge based on product characteristics and runs in web environment is developed. Designers can acquire reliable designing knowledge according to the matching degree.
