摘　　要：采用产品本体理论对设计进行本体标注,得到对应产品设计的形式化概念,在此基础上通过本体的推理———基于描述逻辑的知识推理,对产品进行分类·文中分别就设计的相似性和基于实例的设计中实例间的相似性推理提出了明确的算法,并通过实例进行了说明·A knowledge based similarity-evaluation method for product design is proposed. It requires that semantic annotation is attached to the design cases under investigation. Product ontology is referred to and semantic information is added to product documents for the different aspects of its life cycle. Description logic reasoning is used to build a product conceptual classification tree, and the distances between corresponding concept nodes are taken as the criteria of product design similarity. The algorithm for building the conceptual classification tree is also proposed and validated.
