摘　　要：为提高教育资源的检索效率和准确性,提出了一个基于本体与粗糙集的教育资源检索模型。该模型使用粗糙集理论对教育资源实例基于知识点分类,并且定义了一个模板使用多个加权描述关键字来表示教育资源实例。通过对查询关键字与描述关键字的相似度综合计算,从而提高对教育资源的检索效率。To improve the retrieval efficiency and precision of educational resources, an educational resource retrieval model based on ontology and rough sets theory is proposed, which classifies educational resource instances based on knowledge point by rough sets theory and defines a template to describe educational re- source instances by some weighted descriptive key words. The retrieval efficiency of educational resource is improved through integrating similarity computation between searching key words and descriptive key words.
