[Poster Presentation] Analysis characteristic of user influence and propagators in social media
Minami Uehara, Sho Tsugawa (Tsukuba Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) Recently, the number of social media users has been increasing, and studies for finding influencers on social media have been actively performed. The existing studies show that the influencers have high centrality in the social network among social media users. While many studies focus on the influencer as a role of a node, other roles of a node have been rarely studied. In this paper, we focus on the propagator as well as the influencer as the roles of a node on social media. While the influencer is defined as a user who can spread his/her own posts to many other users, the propagator is defined as a users who can spread other users’ posts to many other users. We investigate the characteristics of influencers and propagators in the social network among social media users. We show that while influencers have high centrality, propagators have relatively low centrality.
