摘要
针对元数据方式管理教学资源的不足,提出一种基于本体和元数据的语义检索系统的框架,讨论了如何构建本体模型,制定元数据方案,设计语义检索机制等问题,并给出了系统实现的方法。
This paper analyzes the defect of the method which manages teaching resources based on metadata and puts forward with a semantic retrieval frame. Then several critical technologys adopted to design the system were discussed, such as the method of developing ontology model, the metadata scheme and the retrieval mechanism. In the end,it talks about how to implement a concrete system by protégé and Jena.
