| 摘 要： | 本体合理有效的存储是保证本体共享利用的前提,现有的关系数据库本体存储模式在存储OWL本体后会出现查询推理效率低、维护困难等问题。文中在分析现有模式的基础上,针对OWL本体类和属性的特点,通过单独设立类关系表、添加关系约束表T-restrict等方法改进已有模式,使其能比较方便地实现OWL本体中类、属性及复杂关系的信息存储,学校本体的存储实例表明存储实现简单,查询实验表明查询检索效率有一定提高,从而说明本体存储模式的设计是可行的。

| Abstract: | The rational storage of ontology is the premise of the shareable use of ontology.Under current ontology storage schema,some problems such as difficult maintenance,low query and inference speed may appear after OWL ontology storing in relational database.Firstly current ontology storage methods are analyzed.Secondly ontology storage schema is designed according to OWL ontology characteristic.The existing design is improved by setting up separate class table,appending relational restrict table T-restrict.As a result,the storage of OWL classes,properties and the complex relations among them is easily realized.Lastly an example of school OWL ontology storage has indicated that the storage method is simple.The query test has proved that the retrieval efficiency is increased.All these explain that the design is feasible. |
