Disseminating Quality-Based Analysis of Microblog Users' Influencing Ability

摘要

In fact, microblog users' influencing ability is the same thing to their spreadability. The research of microblog users' spreadability has received much attention in the past years, towards which most of the existing advanced methods are based on the spread range of users' blogs. However, those methods neglect the blogs' disseminating quality, we find that only the spread range of those blogs with disseminating quality could precisely indicate the spreadability of microblog users, yet those without will jeopardise the precision of the analysis of users' spreadability. In addition, the information dissemination in microblog mainly relies on the followers' reposting behavior, yet the existing methods have not taken much into consideration of the factors that affect the followers' reposting behavior. In this paper, the blogs' disseminating quality in microblog is thoroughly studied. In addition, we propose a method to measure microblog users' spreadability based on the forecast of the spread range of users' blogs possessing disseminating quality. In the analysis, we innovatively combine the users' attention degree received from their followers and interest similarity between them. We conducted several experiments on the real data set of Sina Weibo, a very common and popular microblog in China, and the results prove the accuracy of our method.
