摘要 常规的直接基于关键词的检索技术已不能满足用户的需求。本体具有良好的概念层次结构和对逻辑推理的支持,因而在信息检索,特别是在基于知识的检索中得到了广泛的应用。在分析目前教学资源检索机制存在的缺陷的基础上,提出一种基于本体的教学资源检索方法,构建一个基于本体的教学资源检索原型系统,利用该系统能有效地提高资源的利用率和检索效率。 Base d on the analysis of the defects of the teaching resource retrieval, presents a teaching resource retrieval method based on ontology. Designs the teaching resources retrieval system based on ontology. The system can effectively improve the utilization and retrieval effi-ciency of resources.
