摘要
以异构数据源为研究对象,提出一种基于混合本体的异构数据集成方法。该方法通过建立局部本体、全局本体,以及全局本体、局部本体、数据源之间的映射关系,解决异构数据集成中的语义异构问题,使对全局本体的查询能够转换为对各个底层数据源的查询。将该数据集成方法应用到某高校学科信息检索平台的异构数据集成中,给出了原型系统的实现。
This paper puts forward a method of heterogeneous data integration based on ontology that takes heterogeneous data sources as the object of the study. Through establishing local ontology for every data source, a global ontology and a mapping between them to solve the problem of semantic heterogeneity at hetero- geneous data integration, the query of global ontology can be converted to the query of underlying data source. This method is applied to heterogeneous data integration of a university subject information retrieval platform, and the implementation of prototype system is given in the paper.
