基于本体的异构数据集成中间件研究与实现

The Research and Implementation of Ontology-based Heterogeneous Data Integration Middleware

针对当前异构数据源存在的语义异构问题,将本体引入到了传统的中间件体系架构。通过构建领域本体为相关领域的各局部数据源提供共享概念模型,并通过建立局部本体与领域本体之间的映射来解决各局部数据源之间的语义异构。在映射关系的生成上,创新性地采用了自动与半自动相结合的方式并提出本体自动映射算法,从而为海量异构数据源的自动集成提供了有效的解决方案。

In order to deal with the most serious problem source-semantic heterogeneity,we incorporate ontology into a among heterogeneous data traditional middleware. By constructing a domanial ontology,a uniform conceptive model is provided to every local data source. The semantic heterogeneity between overall ontology and local ontology could be settled by establishing the mapping between them. In this subject we use the way of combining automatic mapping and semi-automatic mapping to generate mapping relations innovatively. And an algorithm is given here. As a result, this way will provide an effective solution to the automatic integration of massive data.
