基于本体的教务数据集成的探析

The ontology-based data integration in education field

高校教务信息管理系统的异构数据源之间存在着各种语义冲突.本文结合本体和中间件方法,通过构建教务管理领域本体,将用户对数据集成的需求利用本体词汇进行表达,在中间层完成全局本体到局部数据源之间的模式映射,以处理教务数据集成的语义需求,对于推动数字化校园建设具有现实意义和实用价值.

Heterogeneous data sources in university Information Management System exist various semantic conflict, this paper combined of ontology and middleware method, by constructing ontology in educational administration domain, using domain ontology vocabulary to express data integration needs, and utilizing a middle layer to complete maapping between ontology vocabulary and data sources for dealing with the semantic data integration needs. This method is of practical significance and practical value for the building of digital campus.
