基于社会网络分析的网络热点事件传播主体研究

The Transmission Disseminator Research of Network Hot Event Based on Social Network Analysis

以天涯论坛为平台,以浙江温岭虐童事件为研究对象,采用社会网络分析方法,通过对该热点事件不同演化阶段的度数中心度、中间中心度、接近中心度、网络密度、群聚系数、网络直径等指标进行对比分析。研究发现在不同的演化阶段都会涌现出一些占据重要地位的参与主体,他们在一定程度上能够推动信息的流动;各信息节点之间没有形成长期稳定的联系,一定程度上信息的传播呈现出复杂化、无方向化和无标度网络特性。

Based on the Tianya BBS, this paper puts the child abuse event in Wenling of Zhejiang as the research object and introduces the Social Network Analysis method into the study. It gives the contrastive analysis from the point centrality, betweenness centrality, closeness centrality, network density, clustering coefficient and network diameter of different evolution stages, finding that in different evolution stage it will emerge important subject who can promote the information flow. But it also concludes that the information network presents complicated, omnidirectional and scale-free characters.
