%X 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.
