Research Of Interest Dissemination On Virtual Community

In recent years, as BBC and SNS prevail in Internet community, more and more netizens have been joining various virtual communities online. They communicate and share stuffs of interest in these communities as virtual persons, and therefore weave a giant and complex network. The pattern that virtual people affect each other and disseminate interest drew wide attention and opinion-dynamics came into being. This paper probes into the law of dissemination of interest from opinion-dynamic perspective.This paper focus on the Internet community which is famous for its sharing and takes data from Douban.com as the subject for study. The writer collected original data by crawler and used preprocessor to select information for analyzing. The analysed data have been used in modeling to look into the Internet community and its members. Complex network and social network analytic approach is used in the modeling of Douban.com. In this model, virtual persons are dots and friendships between them are lines. This paper also includes discussion of parameters of related features in virtual community, such as simulation study on average shortest-paths, clustering coefficient and degree distribution. As a result, it proves that Douban.com fits the features of scale-free network. The virtual persons model is built under the theory of organizational behaviour, has consulted researches concerning the features of virtual human behaviour on the Internet and divides virtual community members into three categories:receiver, dedicator and raver.This paper continued to present an interest dissemination model, which is altered from disease dissemination model known as SIR. It simulates the spread of interest themes and the state changing pattern of virtual individuals by program stimulation. This model is proved reasonable and practical by factual data from Douban.com.
