Consensus with Linguistic Preferences in Web 2.0 Communities

Web 2.0 Communities are a quite recent phenomenon with its own characteristics and particularities (possibility of large amounts of users, real time communication...) and so, there is still a necessity of developing tools to help users to reach decisions with a high level of consensus. In this contribution we present a new consensus reaching model with linguistic preferences designed to minimize the main problems that this kind of organization presents (low and intermittent participation rates, difficulty of establishing trust relations and so on) while incorporating the benefits that a Web 2.0 Community offers (rich and diverse knowledge due to a large number of users, real-time communication).
