In this paper, we present a multiagent system aiming at assisting citizens in the current e-government scenario characterized by a huge amount of heterogeneous services that makes it difficult to quickly answer citizen queries. We show that the adoption of intelligent agent technology makes our system capable of helping a citizen in his search of services in such a way as to satisfy his interests and to face his needs; moreover, this technology ensures a high level of proactivity because it can identify services potentially relevant to a citizen even though he has never required them explicitly; finally, it can enhance citizen participation to decisional processes because it can encourage citizens to form communities who can debate in such a way as to propose the activation of new services of interest to them.Index Terms-e-Government systems, multiagent systems, personalized search of services, social networks.
