“…Creation and maintenance of a community-level collective intelligence push a novel attention to the critical aspects of distributed knowledge management in the P2P environment, where the goal of establishing a shared agreement among a set of peers conflicts with the intrinsic P2P nature that pursues peer autonomy, communication scalability, and rapid change propagation. In this direction, recent approaches based on P2P communities show interesting solutions to improve the efficiency of query distribution and to increase data availability, apart from the accessibility of the single peers (Aiello & Alessi, 2007;Das, Nandi, & Ganguly, 2009). However, methods and techniques for collaboratively building and negotiating any form of P2P community intelligence are still at a basic level of development and only preliminary results are currently available (Aleman-Meza, Halaschek-Wiener, & Arpinar, 2005;Ren, Anumba, & Ugwu, 2002).…”
