      Exploiting locality for scalable information retrieval in peer-to-peer networks 

      Zeinalipour-Yazdi, Constantinos D.; Kalogeraki, Vana; Gunopulos, Dimitrios (2005)
      An important problem in unstructured peer-to-peer (P2P) networks is the efficient content-based retrieval of documents shared by other peers. However, existing searching mechanisms are not scaling well because they are ...

      Finding the K highest-ranked answers in a distributed network 

      Zeinalipour-Yazdi, Constantinos D.; Vagena, Zografoula; Kalogeraki, Vana; Gunopulos, Dimitrios; Tsotras, Vassilis J.; Vlachos, Michail; Koudas, Nick; Srivastava, D. (2009)
      In this paper, we present an algorithm for finding the k highest-ranked (or Top-k) answers in a distributed network. A Top-K query returns the subset of most relevant answers, in place of all answers, for two reasons: (i) ...

      A local search mechanism for peer-to-peer networks 

      Kalogeraki, Vana; Gunopulos, Dimitrios; Zeinalipour-Yazdi, Constantinos D. (2002)
      One important problem in peer-to-peer (P2P) networks is searching and retrieving the correct information. However, existing searching mechanisms in pure peer-to-peer networks are inefficient due to the decentralized nature ...

      On constructing internet-scale P2P information retrieval systems 

      Zeinalipour-Yazdi, Constantinos D.; Kalogeraki, Vana; Gunopulos, Dimitrios (2005)
      We initiate a study on the effect of the network topology on the performance of Peer-to-Peer (P2P) information retrieval systems. The emerging P2P model has become a very powerful and attractive paradigm for developing ...
