| 摘 要： | 了解网民对某一话题所持的舆情观点倾向及其演化过程,是互联网舆情监控的一项重要内容。掌握舆情观点的演化特性对于及时引导和化解舆情危机具有十分重要的意义。考虑到互联网是一连接度分布具有幂律特性的复杂网络,提出了基于BA网络的舆情观点演化模型。模型考虑了个体本身以及个体对他人的信任关系两个因素,重点分析了模型中信任阀值对观点演化过程的影响,并对模型是否考虑网络拓扑结构因素进行了比较分析。

| Abstract: | To learn the tendency and the evolution process of opinions held by Internet users towards a certain topic is an important part in the work of monitoring the online public opinion.To know the evolution features of the public opinion is also of great significance for the timely guidance and solution of the public opinion crisis.Considering that the Internet is a complex network with characteristics of power-law degree distribution,we present an evolution model of public opinion based on BA network.Taking into account individual itself and the trust relationship between an individual and others,the model analyses the influence of the trust threshold on the view evolution,and comparatively analyses whether the model should consider the network topology factor. |
