摘要：

随着社交媒体的发展,突发事件在网络中迅速传播,进而影响事态变化,为公共秩序及社会局势带来严重影响。突发事件的演化研究已成为内容安全领域的重要组成部分。文章通过分析突发事件的基本性质,发现突发事件的演化过程可由具有时序进化结构的潜在话题反映出来。文章设计实现了突发事件话题演化分析系统,结合社交媒体的内容特点,使用动态主题模型,从话题内容和热度两方面,分析公众观点变化,还原事件发展过程。该系统在“韩国部署萨德反导弹系统” 话题分析中取得预期效果,在事态感知领域具有应用价值。

关键词: 突发事件, 话题演化, 动态主题模型, 可视化

Abstract:

With the development of social media, emergencies spread rapidly in the network, which then affects the situation and takes serious impacts on the public order and social situation. So the research on the evolution of emergency has become an important part of the content security field. By studying the basic properties of emergency, it is found that the evolution process of emergency can be reflected by potential topics with sequential evolutionary structure. Combining with the characteristics of social media content and using the dynamic topic model, this paper designs a topic evolution analysis system of emergency, which analyzes public view tendency and restores the event development process from the two aspects of topic content and topic heat. This system achieves the expected results in the topic analysis of "South Korea deploys the THAAD anti-missile system", and has practical value in the field of situation awareness.

Key words: emergency, topic evolution, dynamic topic model, visualization
