| 摘 要： | 针对教育信息基于互联网络的快速增长以及检索日趋复杂等问题,构建了基于领域本体的四层查询体系结构,采用5W1H分析法归纳了领域本体中的概念和关系,建立了基于5W1H的领域本体概念模型,重点研究了基于Jena的领域本体持久化技术和领域本体规则推理技术,设计了基于SPARQL查询规则和基于Jena推理规则的领域信息查询算法。以教师信息为例,采用Jena开发平台和MySQL数据库,实现了教师信息领域本体查询系统的精确查询、模糊查询和语义查询等功能。

| Abstract: | In order to solve these problems such as the rapid growth of educational information based on internet and the increasing complexity of information retrieval, the query architecture is pro- posed using ontology technology which has a four - layer structure. The concepts and relationships are summarized in the ontology by 5 W1 H analysis method, and a conceptual model of the ontology based on 5W1H established; the persistence technology and the ontology rule - based reasoning technology is mainly researched, and the query rules based on SPARQL and the information query algorithm based on Jena reasoning rules are designed. For example, the query functions such as precise query , fuzzy query and semantic query are realized by using Jena and MySQL under the ontology query system of teacher＇s information. |
