在社交媒体时代,风险信息传播的传播过程发生了极大改变,社交媒体的使用对公众风险感知的影响愈发强烈。本研究以2015年11月震惊全球的巴黎恐怖袭击事件为例,运用社会网络分析法,结合风险的社会放大框架对该社会网络中各种关系进行全面、精确的量化分析,研究事件发生后信息传播的动态网络结构。最终结果表明,事件中的风险感知网络是基于关键行动者的动态网络结构,关键行动者掌握重要信息源,中介行动者在风险信息扩散过程中充当意见领袖,使得风险信息在传播中被放大,能更快的传播至普通行动者。
In the era of social media, the dissemination of risk information has undergone a drastic change. The use of social media has become increasingly influential in public risk perception. Taking the Paris terrorist attacks that stunned the world in November 2015 as an example, this study uses the social network analysis method and the risk-based social amplification framework to conduct a comprehensive and accurate quantitative analysis of the various relationships in this social network to study the post-incident information Dissemination of dynamic network structure. The final result shows that the risk perception network in the event is based on the dynamic network structure of the key actors, the key actors have important information sources, and the intermediary actors act as the opinion leaders during the diffusion of risk information. As a result, the risk information is amplified, Can spread faster to ordinary actors.
