A Cooperative Game Approach to Author Ranking in Coauthorship Networks
In this paper, we propose a cooperative game approach to the issue of author ranking in coauthorship networks. We first construct three weighted coauthorship networks from different perspectives and define three cooperative games according to the corresponding coauthorship networks. Then we use the core and the Shapley value as allocation rules for the games. Finally, considering the contribution level of the authors to their papers, we give the weighted Shapley value and a new value as the allocation rules. These allocation rules can be used to rank the authors in coauthorship networks.
