摘要：

随着互联网的普及,论坛,微博,微信等新媒体已经成为人们获取和发布信息的重要渠道,而微博已经成为舆情传播的主要平台,研究微博上舆情信息的传播情况具有重大社会意义,文章基于话题研究微博信息的传播特点.首先,通过对话题传播过程中新增用户数和参与话题用户的累计概率分布的统计,研究用户对话题转发的参与度,总结出话题传播过程,包括产生期,爆发期和衰亡期;接着利用话题中用户的转发关系,整理出话题传播的拓扑结构,通过测量传播拓扑结构中的平均路径,网络直径和聚类系数,并与无尺度网络进行比较,对话题传播拓扑结构进行进一步的分析,总结出传播网络具有小世界特性,这些特性能够加快话题在网络中的传播速度并扩大传播范围.文章研究话题传播的拓扑结构,为研究网络上的微博舆情提供了基础.

关键词: 微博, 话题, 信息传播, 拓扑结构

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
