| Abstract(in English) | We investigate the relation between the sentiment of a message on social media and its virality, defined as the volume and the speed of message diffusion. We analyze 4.1 million messages (tweets) obtained from Twitter. The virality of a message is measured by the number of message repostings (retweets) and the time elapsed from the original posting of a message to its $N$th reposting ($N$-retweet time). Through extensive analyses, we find that negative messages are likely to be reposted more rapidly and frequently than positive and neutral messages. Specifically, the reposting volume of negative messages is as 1.2--1.6 times as that of positive and neutral messages, and negative messages spread approximately 25% faster than positive and neutral messages when the diffusion volume is large. |
