| Abstract(in English) | A purpose of information diffusion performed by information providers is to maximize the total utility of users, such as value and profit. However, influence maximization, which only considers the number of information recipients, does not necessarily maximize the sum of the user utility because the users could have diverse utility functions. With an appropriate assumption on the distributions of the user utility functions, it is possible to further increase the total utility from the total utility obtained by influence maximization. Hence, we formulate a utility maximization problem to model utility functions of users with independent cascade model. We also prove the existence of an approximation method for the problem. Computational experiments on random networks show the usefulness of the utility maximization problem. |
