基于关系数据库存储OWL本体的方法研究

在研究OWL本体的存储模式和现有的基于关系数据库本体存储模式的基础上，本文提出了一种新的基于关系数据库存储OWL本体的方法。该方法根据OWL的构词特征，设计关系表来保存本体中资源之间的关系，描述了特征和约束、刻画了本体的层次和等价等关系，很好地存储了本体的语义信息。它适用于存储大规模的本体，同时大大提高了检索、查询、映射的效率。

On the Method of Storing the OWL Ontology Based on Relational Databases

On the basis of studying the storage patterns of the OWL ontology and the existing storage patterns of ontology based on relational databases,this article proposes a new method of storing the OWL ontology based on relational databases.This method acts according to the structural word characteristics of OWL,designs a relation table to preserve the relations in the ontology between the resources,describes the features and constraints,depicts the levels and equivalence relations of ontology,saves the semantic information of ontology well.The method is suitable for storing large-scale ontologies,and simultaneously enhances the efficiency of searching,inquiry and mapping.
