【摘要】 为进一步提升高校的智慧管理水平,以某高校校园一卡通消费记录为数据基础,利用大数据和数据挖掘技术对其展开分析研究,挖掘学生消费行为背后的隐藏信息.通过对提取数据进行预处理和特征工程,统计分析学生的消费水平和消费习惯;采用聚类算法圈选出具有不同消费行为的学生群体,深度分析不同群体的消费组成结构和消费行为特征;通过构建学生共现网络,研究学生社交关系并发现学生群体中的孤独者.结果表明,利用聚类算法辅助学校资助部门开展精准助学工作是可行的,构建学生共现网络也为高校心理辅导工作提供一定参考依据.更多还原

【Abstract】 In order to further improve the intelligent management level of universities, we use big data and data mining technology to analyze the data including a university’s campus card consumption records. Firstly, through the preprocessing and feature engineering of the extracted data, we analyze students’ consumption level, consumption habits and other laws. Then, we cluster students into different groups with different consumption behaviors, and analyze the consumption structure and consumption behavior characteristics for the different groups in depth. Finally, by constructing a student co-occurrence network, we study the social relationships of students and find the lonely persons. The experimental results show that our clustering algorithm can assist the accurate student aid work, and the construction of the student co-occurrence network can also provide a certain reference for the psychological counseling work.更多还原
