N2 - The past decade has seen vast research on the influence maximization problem in social networks: How to select a subset of individuals to become initial adopters, so that the word-of-mouth effect in the social network is maximized Approximation algorithms have been proposed for this NP-hard problem with knapsack or other constraints. To incentivize influencers to become initial adopters, Singer has initiated budget feasible mechanisms. In this paper, we generalize them to the budget feasible mechanism for k-topic influence maximization problem. We investigate this problem and propose KIMI. We rigorously prove that KIMI achieves 5e/(e-1) approximation and computational efficiency, individual rationality, truthfulness, budget feasibility. Extensive simulations demonstrate that KIMI significantly outperforms baseline methods.
