Efficient peer-to-peer semantic overlay networks based on statistical language models

Alessandro Linari, Gerhard Weikum
2006 Proceedings of the international workshop on Information retrieval in peer-to-peer networks - P2PIR '06  
Our system builds up on the idea of a Semantic Overlay Network (SON), in which each peer becomes neighbor of a small number of peers, chosen among those that are most similar to it.  ...  Peers in the network are represented by a statistical Language Model derived from their local data collections but, instead of using the non-metric Kullback-Leibler divergence to compute the similarity  ...  A technique for doing this is to encode a similarity-based precomputed binary relation among peers into a so-called semantic overlay network (SON) [10, 1] .  ...

SemreX: Efficient search in a semantic overlay for literature retrieval

Hai Jin, Hanhua Chen
2008 Future generations computer systems  
Based on the semantic overlay, a heuristic query routing algorithm is proposed for efficient content searching.  ...  In this paper we present SemreX, a semantic overlay for desktop literature/ document retrieval in peer-to-peer networks.  ...  The key features of the SemreX overlay are that we base a semantic overlay on: (1) a statistical way to measure the similarity between any two distributed peers, (2) document classification algorithm using  ...

Semantic Overlay Clusters within Super-Peer Networks [chapter]

Alexander Löser, Felix Naumann, Wolf Siberski, Wolfgang Nejdl, Uwe Thaden
2004 Lecture Notes in Computer Science  
We introduce the concept of semantic overlay clusters (SOC) for super-peer networks enabling a controlled distribution of peers to clusters.  ...  Our approach is based on predefined policies defined by human experts. Based on such policies a fully decentralized broadcast-and matching approach distributes the peers automatically to super-peers.  ...  Recently semantic overlay networks for peer-to-peer systems [23] allow overlays for placing data nodes semantically together.  ...

Finding and evaluating the community structure in semantic peer-to-peer overlay networks

HanHua Chen, Hai Jin
2011 Science China Information Sciences  
Recently much attention has been paid to semantic overlay networks for information retrieval in large scale peer-to-peer networks, and much research work on semantic overlay protocols and searching algorithms  ...  has been done and the results indicate that semantic overlay is efficient for content searching in peer-to-peer networks.  ...  Traditional peer-to-peer overlays fail to support efficient content based information locating in large scale peer-to-peer networks.  ...

Expertise-based peer selection in Peer-to-Peer networks

Peter Haase, Ronny Siebes, Frank van Harmelen
2007 Knowledge and Information Systems  
Based on the semantic similarity between the subject of a query and the expertise of other peers, a peer can select appropriate peers to forward queries to, instead of broadcasting the query or sending  ...  However, determining the destination peer in the first place is not always trivial. We propose a model in which peers advertise their expertise in the Peer-to-Peer network.  ...  We would like to thank our colleagues for fruitful discussions.  ...

Anis Ismail, Mohamed Quafafou, Gilles Nachouki, Mohammad Hajjar
2011 arXiv   pre-print
The usability of these systems depends on effective techniques to find and retrieve data; however, efficient and effective routing of content- based queries is an emerging problem in P2P networks.  ...  In this paper, we propose an architecture, based on super-peers, and we focus on query routing.  ...  Statistical variables then define performance measures relevant to the user. In this section, we present our P2P network simulator domain-based semantics.  ...
