Advances In Peer-To-Peer Content Search

Content-based search in peer-to-peer networks

Gnutella, a well-known P2P system, uses resources inefficiently when directly applied to information retrieval problems. In this paper we propose an efficient search mechanism that extends the standard Gnutella protocol to support content-based retrieval in P2P networks. The idea is to estimate locally the relevance of peers when they receive query messages. Only those peers estimated as releva...

Content-Based Similarity Search over Peer-to-Peer Systems

Peer-to-peer applications are used to share large volumes of data. An important requirement of these systems is efficient methods for locating the data of interest in a large collection of data. Unfortunately current peer-to-peer systems either offer exact keyword match functionality or provide inefficient text search methods through centralized indexing or flooding. In this paper we propose a ...

Content-Based Search Using Self-Organizing Peer-to-Peer Network

In order for peer-to-peer (P2P) content sharing network to be scalable, it is imperative to efficiently route queries through the network. Semantic based search should, with as little messages (traffic) as possible, return just those relevant documents stored throughout the network thus achieving precision and recall values comparable to those of correspondent centralized system. In this articl...

Peer-to-Peer content search supported by a distributed index in a publication/search model

1 Research fellow at Secretaría de Investigación y Postgrado. Universidad Nacional de Luján. Argentina. ABSTRACT: Peer-to-peer networks (P2P) are considered a valid approach for the construction of distributed systems. Further research projects in the last few years have focused on using this kind of networks as an alternative for solving different situations that have traditionally required ce...
