Our research seeks to put it on a firmer footing by mining these networks from data building probabilistic models of them and using these models to choose the best viral marketing plan. Knowledge-sharing sites where customers review products and advise each other are a fertile source for this type of data mining. In this paper we extend our previous techniques achieving a large reduction in computational cost and apply them to data from a knowledge-sharing site. We optimize the amount of marketing funds spent on each customer rather than just making a binary decision on whether to market to him. We take into account the fact that knowledge of the network is partial and that gathering that knowledge can itself have a cost. Our results show the robustness and utility of our approach.
