基于混合本体的异构数据集成方法研究

Heterogeneous databases integration approach based on mixed ontology

本体以其强大的语义表达和概念推理能力,越来越多的用于解决数据集成中遇到的问题。分析局部本体和全局本体的缺点,提出一种基于混合本体的异构数据集成框架,集成查询模块,屏蔽数据源不同对于用户造成的不便,并介绍了其中的一些关键技术,并集成监控模块,生成本体的构建日志,便于系统的维护和升级。

Ontology has a strong ability in expressing of the semantics and conception speculating,so it is used to deal with the problems in the databases integration.This paper analyzed the weak points of the local and global ontologies,established a mixed ontology framework in the databases integration,integrated the query module,shielded the discrepancy between the different data source,and introduced some of the critical techniques,and integrated the supervisory module,produced the log,it is convenient for system maintaining and upgrade.
