Abstract:

Microblogging users play a vital role in the process of news propagation, and Microblogging users with strong influence are the key factor in public opinion formation, spread and guide. In order to more accurately assess the influence of microblogging users, the UIA (User Influence Assess) algorithm, this paper presented based on user behavior and PageRank, which assess the user's own activity level and the connection degree among the users integratively, present and quantify the related factors that affect the user's own activity level and the connection degree among the users based on that we can analyze user’s behavior, and then come to the proportion of weighting. This algorithm avoided the topic drift phenomenon of the PageRank algorithm, and also systematically measured the user’s influence with highly accuracy.

Key words: UIA, PageRank, user behavior, activity degree, contact degree
