摘　　要：为解决e-learning领域内学习资源的有效检索,提出了一个基于领域本体的e-learning学习资源语义检索模型。用Protégé构建了教育技术领域本体,通过对检索方法的研究分析和算法实现,开发了基于本体语义检索原型系统;并由对比全文检索和基于本体的语义检索两种方法的查准率,证明了基于本体的语义检索方式,在一定程度上能解决目前传统检索中存在的不足。To facilitate the effective retrieval of learning resources, the paper proposed a domain ontology-based model of learning resources. Education technology ontology was constructed by Protégé. Through studying and analyzing the retrieval model and realizing the algorithm, a prototype system was developed. Precision ratio of full-text retrieval and ontology-based retrieval was calculated separately and the latter was more accurate. It is proved that the system can overcome the shortcomings of traditional retrieval at a certain extent.
