| Abstract(in English) | Finding influencers who can spread information to many other users on social media is important for several application domains including viral marketing. In social networks representing relationships among social media users, nodes with high centrality measures have been shown to have high influence on social media. However, most of the existing studies focus on the influence of nodes only at a specific time, and ignore the time evolution of their influence. This paper investigates the time evolution of the influence of central nodes in a social network. We use Twitter data during one year period of 2016, which include follow relationships and records of retweets among 300 thousand users. We identify central nodes in a social network as of January, 2016. We define the influence of a node as the number of retweets to the tweets posted by the node. Our results show that the influence of central nodes are surprisingly stable over one year period. |
