Propagation And Modeling Research Based On WeChat Public Account's Article

With the development of mobile Internet technology, mobile online social network is constantly changing people to exchange information and share the way. Especially in recent years the WeChat public accountfor information dissemination, which, as the current representa-tive of a mobile social applications and new media platform, its timeli-ness, social, privacy features, attract many users to use, carry out infor-mation exchange and sharing. WeChat is currently one of the most pop-ular social media. Reading articles on WeChat public account has be-come a habit for many people. Public account's influence is growing by the day.In this paper, WeChat public account's article pageview data are an-alyzed. It is demonstrated that article pageviews follow power law dis-tribution. This shows that the focus on article will last for long and pageview is predictable. Some classic information spreading models such as SI and SIR models fail to explain the variation regularity of pageview. Since these models assume that the more neighbors who share information to an individual, the larger the spreading rate will be. How-ever, WeChat is quite private circle. The information shared by useronly be shown to people who are user's WeChat friends. The reason user share information is letting his friends know the information. Therefore,the spreading rate is affected by the number of user's friend who have known the information. In contrast to classic epidemic and information spreading models, as the number of people increase,the spreading rate decrease. For example, if all a user's WeChat friends share the same ar-ticle, this user will not share the article at all, namely the spreading rate will be zero. To describe the spreading in WeChat,an information spreading model of WeChat was proposed. The simulation results offer a good fit for the empirical data. The effects of model parameters on spreading process are further analyzed. Our work contributes to reveal the mechanism of information spreading and provide theoretical basis for the supervision of public opinion spreading on WeChat.This article also has carried on the rethinking to Opinion Leader.WeChat public accountis the Opinion Leader in the new media era.Tracing the history and exploring the new development of the concept of "opinion leader" is vital in understanding- the function and role of WeChat public account in hot issues.
