摘要： 提出了一种基于本体语义模型的信息检索方法。该方法充分利用领域本体提供的概念之间的语义相关性，从语义模型扩展、概念相似度、相关度计算，并以用户反馈等角度探讨了基于语义模型的自动推理方法在信息检索中的应用，文章介绍了系统实现框架。该系统将应用在学习资源的智能检索中。

Abstract: A methodology is presented to retrieve information based on semantic ontology model. This methodology uses semantic relevance provided by domain ontology, and the paper discusses how to apply inference in information retrieval. At last, an experiment system is demonstrated. This system will be applied in intelligent retrieval for learning sources.
