摘要: 企业中存在大量语义异构数据源,语义异构阻碍了数据源的查询处理。该文针对这个问题,提出了基于Ontology的语义集成方法,给出了语义异构信息源的查询处理。通过实例验证了方法的可行性。某航空研究所应用表明:该方法可以有效地处理企业中存在的异构数据源查询问题。

Abstract: Semantic heterogeneity baffles query processing on information sources in the enterprise where large numbers of semantically heterogeneous information sources exist. The method of semantic integration based on Ontology mapping is put forward and query processing on semantically heterogeneous information sources is specified aiming at the problem in the paper. An example is given to validate the method. Application in a certain aeronautical institute shows the method can solve the problem effectively.
