Abstract

Influence Maximization is one of the most popular problems in social networks, which has many applications in real-world networks. Influence Maximization is the problem of finding a small subset of nodes (seed nodes) in a social network that could maximize the spread of influence. However, Fairness has not been considered widely in this domain. An important question is whether the benefits of such information propagation in a social network is fairly distributed across different groups in the population. Thus, single-objective Influence Maximization problem turns to the multi-objective problem, in which both the spread of influence and Fairness must be considered. In this paper, we first introduce the measure we use for measuring Fairness in Influence Maximization. Then, we propose an algorithmic framework, based on multi-objective grey-wolf optimizer, for Multi-Objective Optimization of combinatorial problem, and use it to solve the explained problem. Finally, we compare our results on real-world datasets with some greedy algorithm to show the effectiveness of the proposed method. The results show that our algorithm improves both influence and Fairness in the network.
