基于逆向工程的本体构建方法研究

Research on ontology building methods based on reverse engineering

传统正向的本体构建方法需要领域专家的参与,大大降低了开发效率。从逆向工程的角度出发,对本体的构建方法进行了研究。以关系模型为基础,提取出关系数据模式,并在元数据层次上建立了数据源模式与OWL本体之间的映射,实现了本体的逆向构建。最后,根据逆向构建过程给出了一个从关系模式构建OWL本体的原型系统。

Because of the domain expert＇s participation, the conventional ontology building methods are in a low efficiency, The ontology building method is researched from the view of reverse engineering. The information of relationship data mode taking the relationship model is extracted as the base. Meanwhile, the mapping between relational database and OWL ontologies is extablished in the metadata level, Then ontology building methods is accomplished based on reverse engineering. Prototype system based on reverse engineering from relationship mode to OWL ontology is given.
