【摘要】 为了实现异构本体间的互操作,本体映射是最有效的解决方法。在本体映射的研究中,已经有很多文献提出了多种映射方法,比较和分析这些方法后,本文基于Schema映射理论构建了基于视图的本体映射模型。首先生成各局部本体的视图;然后对各局部本体视图概念进行聚类分析生成类聚簇,在此基础上基于概念语义关系将局部本体视图元素合并集成为全局本体视图元素,生成全局本体视图,同时建立起全局本体视图与局部本体视图间的映射关系。该模型增加了本体映射的可理解性和清晰性;适应于动态信息环境;为实现异构本体间信息共享提供了一个可视化的框架。更多还原

【Abstract】 In order to achieve the interoperability among heterogeneous ontologies, ontology mapping is the most effective solution. Based on the investigation, comparison and analysis of current ontology mapping techniques, a view-based ontology mapping model on the basis of schema mapping theory is proposed. Firstly the local ontology views and cluster to the local information classes are constructed according to their semantic relations. Then, on the basis of analyzing the information semantic relations, the local information classes are integrated into the global information classes to construct the global view and the mapping relationship between the global view and the local views. This model can make ontology mapping be comprehensible and clear, is suitable for dynamic information environment, and is helpful to establish a platform for sharing information of heterogeneous ontologies.更多还原
