摘要
针对现行学生综合测评体系中存在的弊端,提出了一种新的学生综合素质评价标准,设计了学生综合测评系统的功能与结构。将数据挖掘的决策树算法应用在系统中,构建了学生综合测评决策树,建立了决策树分类模型,以相应的分类规则对学生数据进行了分类,并进行了更多的挖掘,可以更好地为学院学生管理和用人单位选拔人才提供决策支持。
Aiming at the disadvantages of comprehensive evaluation system of the students,a kind of new student comprehensive quality evaluation standard was put forward,and the structure and function of student evaluation system were designed,then the data mining decision tree algorithm was used in the system,and the student evaluation and decision tree was constructed.Meanwhile,the decision tree classification model was established,the student data were classified according to the classification rules,and more mining was made,which could be better for colleges and employers to provide decision support.
