Abstract(in English) For a successful viral marketing campaign on social media, it is important to spread information to many users. The size of the cascade of information spreading depends on who posts the information and who reposts the information. Therefore, finding influencers who can spread their posts widely and spreaders who can spread other users' posts widely is a key to realize effective viral marketing. Influencers and spreaders on social media may change over time. However, how the influence and spreading power of social media users change over time has not been fully explored. In this paper, we investigate the time evolution of the influence of influencers and spreading power of spreaders on Twitter. We extract influencers and spreaders and track their influence and spreading power over a one-year period. Our results show that the influence of influencers and spreading power of spreaders are generally stable, and 50--60% of influencers and spreaders have highly stable influence and spreading power. Moreover, we discuss the characteristics of the stable influencers and spreaders using their centrality measures.
