Ranking the Authority of Name Aliases for Email Users

Identifying information telling real identity of users from emails is an important topic in email mining. This paper focuses on the problem to identify the most authoritative aliases of email users. Based on the facts that different aliases of the same user take different positions in the user's email communication relation and that af final aliases of the same user have similar morphology in linguistics, a novel method to rank alias authority and obtain the authoritative aliases of an email user by email communication relation analysis and morphologically similar alias clustering is proposed. Experimental results show that the proposed approach can efficiently find the authoritative aliases of a user and can be applied to many applications on emails such as identity identifying, social relation discovering, important people finding and so on.
