Construct the Students' Consumption Portrait Based on Large-scale Campus Data

The consumption data of campus card can effectively represent students' life records, and it is extremely important to deeply understand their consumption feature. In this paper, we proposed a method to describe students' consumption behavior by using features. According to the students' consumption records of campus card, we extracted 7 features from three aspects of their living habits, affluence and life trajectory. Three different levels of values were assigned for each feature to illustrate the consumption differences among students. Through these features, we constructed portraits of campus consumption for students. We could attach labels to each student to describe their campus consumption behavior and show their different living habits from others.
