摘 要: 针对某航空研究所存在的多数据源集成问题,本文提出了基于Ontology的多数据源语义集成方法,该方法采用Ontology描述数据源语义,通过多Ontology之间的映射实现多数据源之间的语义集成。该方法已成功用于某航空研究所。 The semantic integration method based on ontology for multiple data sources is proposed to solve the multiple data sources integration in a certain aeronautic institute. In this method, ontology is used to describe the data sources semantically and semantic integration for multiple data sources is realized by the mapping among multiple ontologies. The method has been used in a certain aeronautic institute successfully,
