Research on group behavior characteristics of microblog users in crisis situations

摘要：

Based on datasets collected from weibo.com, the paper presents an empirical analysis of the group behavior of microblog users in crisis situations. The result shows that the time interval between two consecutive microblogs follows a power-law distribution. But users post microblogs more often than they do in everyday situations and incline to post them by computer. Secondly, the average length of microblogs in crisis situations hasnD changed significantly; while mcroblogs related with crisis situations are posted only once by most users and always get more forwardings and comments. Furthermore, users concern a lot at the early stage of crisis situations and then their interest decays over time.The findings are helpful for monitoring public opinion and optimizing communication mode in crisis situations.
