As Web-based online communities are rapidly growing, the agents in social groups need to know their measurable belief of trust for safe and successful interactions. In this paper, we propose a computational model of trust resulting from available feedbacks in online communities. The notion of trust can be defined as an aggregation of consensus given a set of past interactions. The average trust of an agent further represents the center of gravity of the distribution of its trustworthiness and untrustworthiness. And then, we precisely describe the relationship between reputation, trust, and average trust through a concrete example of their computations. We apply our trust model to online Internet settings in order to show how trust mechanisms are involved in a rational decision-making of the agents. © Springer-Verlag Berlin Heidelberg 2007.
