A Friend Recognition Method Based on Campus Card Data

Abstract

With the increasingly rapid development of information age, we ushered in the era of big data[1,2]. It is attractive to many experts and scholars to explore the mystery of human life and society with the big data. Aiming at the identification of friend relationships, a new method based on campus cards and big data has been proposed which includes four steps, namely data preprocessing, generation of similar behavior matrix, determination of similar behavior threshold and identification of friend relationships. And compared to the traditional questionnaires, this method is more practical and instructive. Furthermore, it is found that 45703 pairs of students have been identified as the friends to each other through the campus card data in library. Besides, the friend network diagram has been built, based on which education administrators could better guide students’ campus lives and some businesses could advertise more precisely and efficiently.
