基于语义Web的网络学习资源库本体实现

Implementation of Ontology in E-learning Resource Repository Based on Semantic Web

将语义Web技术引入网络学习系统,构造了一个基于语义Web架构的网络学习资源库本体,实现对网络学习系统中学习资源的管理。在分析本体建模方式以及网络学习资源库基本功能的基础上,定义了由学习资源本体和用户本体组成的学习资源库顶层本体,并给出系统类图,在Protégé3.1中实现了本体建模,给出了基于OWL的本体描述,对定义的本体进行了评估,并用基于本体的推理实例验证了本体的有效性。

The semantic Web technology is introduced in the E-learning to construct a learning resource ontology based on semantic Web architecture and realizes further management of the learning resources in E-learning system. After analyzing the functions and scope of Web-based education resource library and the methods of ontology modeling, upper ontology is illustrated which includes the resource library ontology and the users＇ ontology. And the class diagram is shown. Corresponding OWL description of ontology is implemented with Protégé3.1. The evaluation of ontology is given, and an inference instance proves its validity.
