摘　　要：针对产品设计过程知识重用的要求,根据知识表示方法的特点,采用本体知识表示方法构建产品设计过程知识本体模型,运用基于属性名称计算相似度关系法作为本体映射决策策略。在选择人力资源管理中的设计部门本体作为产品设计过程本体的异构本体的基础上,建立二者的映射关系,并结合语义词典法和分词矩阵法对异构本体之间存在的匹配概念集合的每一对匹配概念对进行语义相似度计算,最终发现异构本体之间的语义本体映射关系,输出映射关系表。For the requirements of knowledge reuse in product design process,according to the characteristics of the knowledge representation methods,we use ontology knowledge representation method to construct the product design process knowledge model and select an ontology mapping decision strategy which is based on attributive name to calculate the ontology semantic similarity.On the basis of choosing design department ontology in human resource management as the heterogeneous ontology of product design process ontology,their mapping relationship is established.Then,the semantic dictionary and the word matrix is used to calculate the semantic similarity for each matching concept of the ontology matching concept set in the heterogeneous ontology.Finally,we find the semantic ontology mapping relationship between heterogeneous ontology and output the mapping relationship table.
