Research on the characteristics of netizens’emotional communication in predictable disaster

以台风“山竹”为例,基于微博数据,综合运用社会网络分析、文本情感分析等方法,分析网民情感传播网络的结构特征、传播层次及路径,探究关键节点的情感影响力和传播路径上的情感变化,并总结出网民情感传播特征。研究结果表明:可预测性灾害中灾前阶段的网民情感传播最为活跃,变化也更为复杂;网民情感传播路径较长,情感倾向会受到多个传播节点直接和间接的综合影响;网民情感传播路径上转发量较大的关键节点对网民情感的影响力更为显著。

Taking the typhoon“Mangosteen”as an example,based on the Weibo data,using social network analysis,text emotion analysis and other methods,this paper analyzes the structural characteristics,communication levels and paths of netizens’emotional communication network,explores the emotional influence of key nodes and the emotional changes on the communication path,and summarizes the characteristics of netizens’emotional communication.The results of the study include:the Netizens’emotional communication in the pre-disaster stage is the most active and the changes are more complex;netizens’emotional communication path is long,and their emotional tendency will be directly and indirectly affected by multiple communication nodes;the key nodes with a large amount of forwarding on the emotional communication path of netizens have a more significant impact on netizens’emotions.
