| Abstract(in English) | We have proposed a problem called influence maximization for unknown graphs, and a heuristic algorithm for the problem. Influence maximization for unknown graphs is the problem of detecting a set of influential nodes in a social network only using the limited knowledge on its topological structure, which is obtained by limited number of probing. In this paper, we extend the method for probing used in our previous algorithm, and propose an influence maximization algorithm for unknown graphs, which we call IMUG-RF (Influence Maximization for Unknown Graphs with Random Flight). IMUG-RF greedily probes the node with the highest expected degree and also periodically probes a randomly selected nodes in the network. Through simulation, we show that IMUG-RF can successfully identify influential seed nodes in real social networks. |
