为了实现ICAI中知识点的自动识别,提出了一种适合计算机处理的知识点分类方法,又利用人工统计的方法提出了知识点模式的概念,利用正则表达式将知识点模式表示成知识点规则,利用决策树C4.5算法实现了自动识别。
In order to realize the automatic identification of knowledge points in ICAI, this paper proposes a knowledge point classification method suitable for computer processing, and proposes the concept of knowledge point pattern by means of artificial statistics, and uses the regular expression to represent the knowledge point pattern as the knowledge point rule , Using the decision tree C4.5 algorithm to achieve automatic identification.
