随着在线教育的快速发展,高质量题库的自动化生成需求日益迫切。现有题库自动生成方法主要分为两类:基于教材内容生成的方法存在准确率不足的问题,而基于PDF题库解析的方法由于格式多样性导致普适性较差。为此,提出一种结合知识图谱与混合Embedding的题库生成系统。采用多模态PDF解析技术处理文本、公式等异构内容;构建知识点图谱,实现题目—答案—知识点的语义关联;设计混合匹配算法,融合结构特征与语义特征进行精准对齐。实验结果表明,所提系统在问题—答案解析匹配任务中达到70.68%的准确率,在题目—知识点对齐任务中达到82.95%的准确率。该系统具有良好的普适性,与教师审核机制结合后可快速应用于CFA考试、医师资格考试等专业领域。
With the rapid development of online education, the automatic generation of high-quality question banks is increasingly urgent. The existing methods for automatic generation of question bank can be divided into two categories: the method based on textbook content has insufficient accuracy, while the method based on PDF question bank analysis has poor universality due to the diversity of formats. Therefore, a question bank generation system combining knowledge map and hybrid embedding is proposed, which uses multimodal PDF parsing technology to process text, formula and other heterogeneous content; Construct a map of knowledge points to realize the semantic association of question answer knowledge points; A hybrid matching algorithm is designed to fuse structural features and semantic features for precise alignment. The experimental results show that the proposed system achieves an accuracy rate of 70.68% in the question answer analysis matching task and 82.95% in the question knowledge point alignment task. The system has good universality and can be quickly applied to professional fields such as CFA examination, physician qualification examination, etc. after being combined with the teacher review mechanism.
