摘　　要：现有的、传统的数据交换方式只能在结构层次上交换异构信息而没有解决交换信息的语义异构问题。该文在研究异构数据源的语义异构问题和本体(Ontology)在数据集成中的优势的基础上,提出一种新的基于局部共享本体的数据集成方式;然后提出了一种开放的基于本体、XML和消息机制地智能数据交换模型;最后讨论了本体及其映射的构建方法。The traditional data exchange model can only use to exchange the information on the structure level, but is not able to solve the semantic heterogeneity. In the paper, based on the analysis of the problem of semantic heterogeneous in the data exchange of the heterogeneous data sources and the advantages of the ontology in the data integration, a new way of data integration based on local shared ontology is put forward. Then an opening data exchange model is proposed, which is based on local shared ontology, XML and message mechanism. Lastly, it researches the construction method of the ontology.
