权重算法在计算移动用户重入网的应用

Weight Algorithm in Computation Mobile Subscriber Re-entry net's Application

结合使用TFIDF权重和Cosine类似算法,通过对多个相似用户常拨打的(10 0个)号码的权重和相似度进行分析,从而达到判断多用户是否为同一用户的目的。为电信运营企业预测经营趋势,及时规避用户发展中存在的风险,提供较为准确的判断依据。

This paper presents an algorithm based on the TFIDF weights and Cosine-Like algorithm to determine whether several cards are used by a single user.
