Abstract: Discovering teams of experts in social networks has been receiving the increasing attentions recently. These teams are often formed when a given specific task should be accomplished by the collaboration and the communication of the small number of connected experts and with the minimum communication cost. In this study we propose a game theoretic framework to find top-k teams satisfying such conditions. The importance of finding top-k teams is revealed when the experts of the best discovered team do not have an incentive to work together for any reason and hence we must refer to the next found teams. Finally, the local Nash equilibrium corresponding to the game is reached when all of the teams are formed. The experimental results on DBLP co-authorship graph show the effectiveness and efficiency of the proposed method.
