In the past years, federated search over Peer-To-Peer (P2P) networks has attracted considerable attention from the information retrieval community. Most previous work assumes a so-called cooperative environment, where each peer can actively participate in information publishing and document indexing in a distributed manner. In contrast, little prior work has addressed the problem of incorporating uncooperative peers, which do not publish their own corpus statistics over a network. In this paper, the authors present a P2P-based federated search framework named PISA, which incorporates uncooperative peers when providing search service.
