Virtual Communities are open socio-technical structures wherein autonomous entities (i.e. agents) with common interests join together to mutually satisfy their goals. The success of these communities relies on collaboration and resource sharing principals, making trust a priority for each member. Such communities need a more flexible trust model wherein both individual (i.e. usercentred) and collective (i.e. community-centred) trust requirements are considered in the decision making-process. This paper reports our on-going e orts in that perspective and presents a multiagent- based Adaptive and Socially-Compliant Trust Management System (ASCTMS). Policies are used, in the system, to specify individual and collective trust requirements, while meta-policies enable agents to dynamically adapt their policies. The ASC-TMS allows agent to make socially-compliant trust decisions through automatic combination of individual and collective policies.
