摘要
高校信息系统经过多年运行,积累了海量综合反映学生各方面学习特征的数据,充分利用这些信息将极大改进教学工作。但从这些海量数据中提取出规律性的信息并指导教学工作,却是信息系统使用的瓶颈。文本提出了采用C4.5决策树这一数据挖掘领域的重要算法,为海量数据提取提供了一条行之有效的途径。
through many years’ running ,the college information system has accumulated masses of data reflecting various learning characteristics of the students and the full utilization of such informa‐tion will improve teaching greatly .However ,it is a bottleneck for the use of information system to ab‐stract regular information from these masses of data and guide teaching .In this paper ,it is proposed o apply C4 .5 decision-making tree ,an important algorithm in data mining field to provide an effective approach for the extraction of masses of data .
