基于决策树算法的留学生安全预警系统的设计与实现

Design and implementation of international students’ security early warning system based on decision tree algorithm

近年来,来华留学生人数呈逐年递增的趋势,这大大增加了管理者对留学生学业情况、人身安全以及国家安全管理的难度.如何对潜在的安全问题进行预警,在安全事故发生前及时采取有效的预防措施成为各高校国际交流学院的重要问题.本系统采用决策树算法中的ID3算法建立留学生安全预警模型,将学生信息作为数据,找到可能发生安全事件的学生,并对这类学生进行预警.本系统的设计可以促进各学校留学生安全管理工作的顺利开展,同时也能够防患于未然,加强对留学生人身安全以及国家安全的保障.

In recent years,the number of overseas students coming to China has been increasing year by year,which greatly increases the difficulty for managers to manage students in academic,personal safety and national security.How to provide early warning of potential security problems and take effective preventive measures in time before a security incident becomes an important issue for each university's school of international education and exchanges.Information technology can provide the necessary technical support for solving these problems.The system can use the student information as data,find the students who may have security incidents through the decision tree early warning model,and provide early warning to these students.The design of this system can promote the smooth development of the safety management of international students in each school.At the same time,it can prevent problems before they occur,and strengthen the protection of international students'safety and national security.
