摘要： Web网上存在着大量题目资源，学生在学习过程中需要准确找到与其所学知识真正相吻合的题目。但是从题目的语言表述往往很难获得其语义信息，合适的题目难以找到。该文提出了一种基于Ontology和描述逻辑推理的Web题目资源检索方案。该方案通过为Web题目资源添加语义注释，并通过描述逻辑推理完成基于语义的题目资源检索，使学生获得与其所学知识语义相关的题目。采用OWL描述Ontology、使用推理机RACER实现描述逻辑推理。

Abstract: Students need to get problem resources that exist largely in Web through a precise and efficient way. But it is difficult for students to get what they really want, which are in correspondence with the knowledge they have already acquired. To solve this problem, this paper proposes a method of retrieving Web problem resources based on ontology and description logics (DL). It adopts OWL to express ontology and use RACER as a DL reasoner to fulfill description logic inferences.
