多源数据融合视角下的大学生“消费-学业-社交”画像构建研究

Purpose/Significance] Mining college student data and constructing studnet profiles is conducive to in-depth understanding ofstudents' needs, improving management level, and promoting intelligent service. [Method/Process] Based on the multi-source datamainly generated by the management and service process of colleges and universities, student profiles were developed by focusing onconsumption, academic and social indicators, analyzing the characteristics of students, using the Scikit-Learn tool of Python, andapplying the K-means clustering algorithms. Empirical research was carried out and representativeness of student portraits fromindividual and group perspectives was studied. [Results/Conclusions] First, this paper attempts to utilize a new data fusion perspective,by fusing explicit data with implicit data, and generating three-dimensional indicators of consumption behavior, academic behavior, andsocial behavior. Secondly, in order to solve the problem of single application scenario in previous research, the method of user profileconstruction is used to realize the fusion of multiple scenarios. Finally, based on the real student data, this study uses K-means clusteringalgorithm to select groups of students with different characteristics on the basis of previous research. The data of college students isanalyzed, and further empirical research is carried out to describe the "consumption-academic-social" profiles of college students.Constructing student profiles from the perspective of multi-source data fusion can effectively provide a basis for decision-making bydifferent units in colleges and universities, such as academic affairs,. Especially in the post-epidemic era, the profiles of college studentscan detect potential risks in time. The study found that at the individual level, by interpreting the label information of students' portraits,it is possible to understand the 3 aspects of students' consumption, academics and social interaction, and realize dynamic monitoring ofindividual students. At the group level, through cluster analysis, students with different characteristics can be selected, especially interms of consumption behavior, and the characteristics of students' activity and stability can be deeply analyzed, which can not onlyprovide a basis for the macro-level observation of students, but also provide new ideas for exploring the correlation between differentbehavioral elements of students. At the application level, the integration of multi-scenario student profiles can simultaneously realizeabnormal identification and early warning, group attention and guidance, and resource planning and adjustment, which greatly broadensthe application scenarios of research and improves the energy efficiency of education and teaching management in colleges anduniversities. However, due to the limitations of data and algorithms, the accuracy and ease of use of student portraits still need to beimproved. There are both constraints from practical conditions and insufficient research methods. In future research, more extensiveresearch should be used to improve college student profile construction system, and constantly develop more suitable techniques.
