Abstract

Abstract:

With the prevalence of Internet, network forum, Microblog, WeChat, etc. are an important channel for people to obtain and publish information. However, Microblog has become the main platform of public opinion spread. In order to study diffusion and supervision of the public opinion, we used a special crawler to collect the topics information and related user data from the microblog network, analyzed the result of the data acquisition, and chose the appropriate social topics information to carry empirical research. Information propagation characteristics of Microblog topics were summarized by studying the users, participation in the topics diffusion. By the forward relationship of users in the topics, the topology structure of the propagation networks of topics was sorted out. Further analysis was carried out on the topology structure, and the results show that the propagation network of microblog topic has small-world properties, which can speed up the diffusion speed and expanding the scope of the spread in the network. Study of topology structure for the spread of topics information can provide basis for studying rumors' diffusion and control on the network and studying users, behavior and the influential users.

Key words: microblog, topics, information dissemination, topological structure
