As one topic of the hottestmicroblog research, microblog users’ influence on the network hasimportant theoretical and practical significance of the dissemination ofinformation, the microblog integration and promotion as well as ofmonitoring and guiding public opinion. In this paper, with an example ofSina Weibo, a new method to collect information from microblog is firststudied. And it gives a data base for a microblog research. And then, amethod for calculating the influence of microblog users is proposed.For Sina Weibo data acquisition, this paper analyzes the data to becollected in Sina Weibo, and then analyzes the shortcomings of SinaWeibo API data collection, and then proposes a new Sina Weibo datacollection method based on Phantomjs and a detailed description of therelated acquisition technology and data structures of content acquisitionand storage. And ultimately, by comparison with Sina Weibo API dataacquisition, a new Sina Weibo data collection program is designed, andaccording to the program, Sina Weibo data acquisition system is designed,too. Through experiments, this method can be proved efficient incollecting Sina Weibo data.For Sina Weibo users’influence, this paper analyzes the compositionsof user’s influence with reference to PageRank algorithm, presents withconcepts of user’s own influence and the user’s ability of being influenced,obtains the results that the user influence is drawn from this fans’ owninfluence multiplied by their ability of being influenced plus the user’s own influence.
