信息安全突发事件情感领袖群际效应研究

Research on the Intergroup Effect of Emotional Leaders in Information Security Emergencies

现实中频发的信息安全事件使人们借助微博等社交媒体发表看法、宣泄情感,形成网络舆情,社交媒体上情感的宣泄使网民群体情感的波动在信息安全突发事件网络舆情的治理中产生重要的作用。然而,已有研究较多关注网络集群行为本身,较少有研究对信息安全突发事件网络舆情中网民群体情感的形成机理进行深入探讨。在此背景下,对信息安全突发事件网络舆情中网民群体情感的形成机理进行研究,提出情感领袖和集群情感的概念,分析微博中信息安全突发事件的用户评论数据获得情感分类和情感得分,采用社会网络分析与文本情感分析结合的方法识别情感领袖,借助情感传播分层网络建立集群情感传播模型,分析集群情感的演变过程并描绘其传播网络,挖掘情感领袖在信息安全突发事件中的集群情感效应。以360云盘关闭事件为研究案例,研究结果表明,此案例微博评论中负面情感所占比例较大;情感领袖在集群情感的形成中产生群际情感效应和群际认同效应,并且在情感领袖的情感传播过程中促进新的集群情感产生;不同情感类型的领袖引发的群际效应趋于一致,即都使新的集群情感强度减弱;情感复杂度先增强后减弱,并且随着集群情感整体规模的扩大,集群中情感表达为中性的情感比例增大。研究结果表明,信息安全突发事件网络舆情传播中存在情感领袖,并且情感领袖会在集群间产生群际效应,揭示了信息安全突发事件网络舆情中网民群体情感的形成机理,丰富了对情感领袖在信息安全突发事件网络舆情方面的群际效应研究。研究结果对网络舆情监管部门如何利用情感领袖的群际作用治理信息安全突发事件网络舆情具有指导意义。

In reality,a whole train of information security emergencies make people express their views and feelings through the social media such as micro-blog,which eventually leads to online public opinion.When governing the network public opinion of information security emergencies,the fluctuation of netizens’group emotions plays an important role because of their emotional expression on social media.However,much attention has been paid to the collective behavior of network,while less attention paid to understanding of the formation mechanism of collective emotion in information security emergencies.In view of the online public emotion formation of the users’emotion of information security emergencies,we put forward the concepts of emotional leaders and collective emotions.Besides,we analyzed the users’comments of information security emergencies in micro-blog to get emotional classification and emotional scores.Then we identified the emotional leaders which is based on social network analysis and sentiment analysis.Eventually,we use the hierarchical network of emotional communication to establish the formation model of the collective emotion.The model analyzed the evolution process of collective emotion and described its communication network in order to further explore the emotional effects of emotional leaders in information security emergencies,which enriches the research of online public perspective of information security emergencies.In this research,the event which 360 Cloud Disk was closed is taken as a research case.Followings are results:①the negative emotions accounted for a large proportion in the online public opinion;②the emotional leaders have the intergroup effects on emotion and identification in the formation of the collective emotion and will promote the formation of new collective emotions in the emotion propagation process of emotional leaders;③the intergroup effects caused by emotional leaders of different emotional types tend to be consistent,that is,they will weaken the emotional intensity of the new cluster,and the emotional complexity will increase first and then decrease;④With the expansion of the overall scale of the collective emotion,the proportion of neutral emotional expression in the collective emotion is increases.The findings indicate that there exists emotional leaders in online public opinion of information security emergencies,and they will form intergroup effects between clusters.This study reveals the formation mechanism of collective emotion in information security emergencies,which enich the influence mechanism of emotional leaders on the intergroup effect in information security emergencies.Meanwhile,the research findings are also instructive or the network public opinion supervision department,which can help govern to manage the network public opinion of information security emergencies by the inter-group role of emotional leaders.
