Demo of P2Prec: a Social-based P2P Recommendation System

The general problem we address is large-scale content sharing for on-line communities. Consider, for instance, a scientific community (e.g., in bio-informatics, physics or environmental science) where community members are willing to share large amounts of documents (including images, experimental data, etc) stored in their local servers. Assume also that they don’t want to lose control over their data at a central site. A promising solution is to organize community members in a peer-to-peer (P2P) overlay network, with the advantages of decentralized control, peer autonomy and scalability.
