摘要: 为解决实际教学过程中教学内容较多的问题,提出面向教学的知识点定义,在基于切分单元的最大匹配算法基础上,结合优化规则进行知识点提取。在知识点的关系提取中,使用关联规则和混合分类方法,用于提高知识点关系提取的正确率。利用获得的知识点及其关系,建立面向教学内容的知识结构图。实验结果表明,该方法适用于中文知识点关系的提取。

Abstract: In order to solve practical teaching in the teaching content, this paper puts forward the definition of knowledge oriented to teaching, and based on the maximal matching algorithm segmentation unit foundation. In the relationship of extract knowledge, combines with the association rules and mixes classification method, and improves the accuracy of knowledge relation extraction. Using the obtained field text knowledge and its relationship, establishes the knowledge structure graph oriented to teaching content. Experimental results show that the method is suitable for extraction of Chinese knowledge point relationship.
