Trust is a human-related phenomenon in social networks. Trust research on social networks has gained much attention on its usefulness, and on modeling propagations. There is little focus on finding maximum trust in social networks which is particularly important when a social network is oriented by certain tasks. In this paper, we first propose a trust maximization algorithm based on the task-oriented social networks. We then take communication cost into account and introduce four different trust optimization algorithms. We also conduct extensive experiments to evaluate the proposed algorithms and test their performance. To our best knowledge, this is pioneering work on trust optimization in task-oriented social networks.
