Diverse peer selection in collaborative web search

Le-Shin Wu, Filippo Menczer
2009 Proceedings of the 2009 ACM symposium on Applied Computing - SAC '09  
To deal with overlapping document collections we propose a diverse peer selection approach for adaptive query routing.  ...  Effective peer selection for intelligent query routing is a challenge in collaborative peer-based Web search systems, especially unstructured networks that do not have any centralized control of peer document  ...  In the face of these limitations, we propose a peer selection algorithm that only uses local information, such as queries and responses, as a basis to consider the collection overlap among peers for query  ...

Improving Information Retrieval Effectiveness in Peer-to-Peer Networks through Query Piggybacking [chapter]

Emanuele Di Buccio, Ivano Masiero, Massimo Melucci
2009 Lecture Notes in Computer Science  
This work describes an algorithm which aims at increasing the quantity of relevant documents retrieved from a Peer-To-Peer (P2P) network.  ...  The algorithm is based on a statistical model used for ranking documents, peers and ultra-peers, and on a "piggybacking" technique performed when the query is routed across the network.  ...  the use of piggybacking for Information Retrieval (IR) across P2P networks at retrieval level in the way reported in this paper.  ...

DHTs over Peer Clusters for Distributed Information Retrieval

Odysseas Papapetrou, Wolf Siberski, Wolf-Tilo Balke, Wolfgang Nejdl
2007 Advanced Information Networking and Applications  
Thus, the key to exploiting DHTs for distributed information retrieval is to reduce index maintenance. We show that this can be achieved by combining DHTs with peer clustering.  ...  Distributed Hash Tables (DHTs) are very efficient for querying based on key lookups, if only a small number of keys has to be registered by each individual peer.  ...  To our knowledge, the combination of DHT and super-peers for P2P information retrieval has not been proposed yet. Basic Algorithm Let us now present our basic algorithm.  ...
