We compute the integrated concept similarity by three aspects: definition, instances and structure; we compute integrated property similarity by three aspects: name, domain and range. ( 3) In addition, this paper have studied other links in ontology mapping. 对于概念的相似度,从定义、实例、结构三方面综合计算;对于属性相似度,从名称、定义域和值域三方面综合计算。(3)另外,本文对本体映射的其他环节也进行了研究。
