In microblogosphere, some microbloggers are not only active but also influential, called them key microbloggers, who enable information diffuse faster, wider and deeper. The knowledge of key microbloggers is crucial for developing efficient methods to either hinder the rumor spread or promote useful information dissemination. In this paper, we discuss how to evaluate a microblogger's influence, investigate microblogging-specific features that constitute a microblogger's active index, and present a model attempting to quantify key microbloggers. We conduct experiments with data, which was crawled from Sina Weibo, and evaluate ranking accuracy of the proposed model. Experimental results attest that the proposed method is able to identify key microbloggers effectively in the microblogging behavior.
