摘要
本文充分利用已有的学生心理测量结果与学生的基本信息,将数据挖掘技术嵌入到心理档案系统中,使用C4.5算法生成了决策树,并提出了一种新的决策树剪枝方法,该剪枝方法能够有效地屏蔽掉置信度较低的导出规则,极大提高了导出规则的有效性和准确性,为构建科学的大学生心理档案服务体系和模式奠定坚实基础,使大学生心理档案系统在心理健康教育中发挥高效、便捷的作用。
The author of this paper,based on the existing psychological measurement results and the personal data of college students,embedded the data-mining technique into the psychological files system and generated a decision,using C4.5 algorithm.In addition,a new pruning method to shield off the derivation rules of low confidence degree was formulated,resulting into the significantly improved efficacy and accuracy of derivation rules,which can serve as a firm basis for a more scientific system of psychological files.
