异构本体集成中基于视图的映射方法*

对现有本体映射方法进行比较和分析后，提出了一种基于视图的映射方法。本体视图实际上是对本体的抽取，即本体的一种应用模式。作为对用户知识的反映它不仅增加了本体映射的可理解性和清晰性，同时也简化了用户对信息的检索。通过构造本体视图间的双向映射关系，既保证了信息查找和定位准确、高效，又提高了映射关系的可扩展性，使本体映射更适合动态变化的信息环境。

View based mapping method in heterogeneous ontologies integration

After comparing and analyzing current ontology mapping techniques,this paper proposed a view-based ontology mapping method.The ontology view was actually the extraction of ontology,namely an application mode of ontology.As the reflection of user knowledge,it not only could make ontology mapping comprehensible and clear,but also could simplify uses information retrieval.Through constructing bidirectional mapping relationships among ontology views,the information search and localization are more accurate and fast,and enhances the extensionality of mapping relationships,consequently the ontology mapping is more suitable for dynamic information environment.
