Mining Call Spammers from Logs

In China, many mobile phone users have become the victim of spam calls and suffered heavy financial loss. Discovering of call spammers can benefit mobile network operators as well as users. In this paper, we propose a time-based graph model and a simple and effective Call Log Rank(CLRank) algorithm with ranking and classification were proposed to find potential call spammers. Experimental results show that our proposed model can find spammers from call logs automatically, dynamically and effectively (with 84.5~91.8% of accuracy) without any manual interventions.
