数据集成的难点是如何解决数据之间的语义异构问题,本文利用本体在语义集成上的优点,提出了一种基于本体语义映射的数据集成框架.根据本体概念的定义及其结构,给出了一种本体语义映射算法,该算法通过属性集合间的比较确定概念语义关系,在计算概念相似度时,考虑了概念名称、概念属性集合和相关概念的语义信息.最后通过概念的属性集映射算法和概念映射算法实现了本体语义映射,从而重点解决了数据集成中的语义映射问题.
數據集成的難點是如何解決數據之間的語義異構問題,本文利用本體在語義集成上的優點,提齣瞭一種基于本體語義映射的數據集成框架.根據本體概唸的定義及其結構,給齣瞭一種本體語義映射算法,該算法通過屬性集閤間的比較確定概唸語義關繫,在計算概唸相似度時,攷慮瞭概唸名稱、概唸屬性集閤和相關概唸的語義信息.最後通過概唸的屬性集映射算法和概唸映射算法實現瞭本體語義映射,從而重點解決瞭數據集成中的語義映射問題.

The difficulty of data integration is how to solve the problem of heterogeneous semantics. Using ontology's advantage in semantic integration, this paper designs a data integration frame based on ontology semantic mapping. According to the definition and structure of the ontology concepts, an ontology semantic mapping algorithm is given, which confirms the concepts' semantic relationship by a comparison between attribute sets, and takes the semantic information of concept names, attributes and correlative concepts into account when the similarity degree is computed. Finally, the ontology semantic mapping is determined by the mapping algorithm of the concepts' attribute sets and the concepts' mapping algorithm. Therefore the problem of semantic mapping in data integration is solved properly.
