An Extraction Method of Influential Nodes Considering Update of Social Network
Masaki Oono (UEC Tokyo) AI2012-7
Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we focus on the target set selection problem, which involves discovering a small subset of influential nodes in a given social network, to perform a task of information diffusion. Kempe’s method based on a general greedy algorithm can give a good approximate solution for the target set selection problem. However, the approximation performance of Kempe’s method deteriorates because the method doesn’t consider the change of the number of nodes and the number of edges of given network. In this paper, we propose a new method to extract the influential nodes efficiently from the dynamic social network.
