Adaptive Semantic Indexing of Documents for Locating Relevant Information in P2P Networks

#
 Locating relevant information in Peer#to#Peer (P2P) system is a challenging problem. Conventional approaches use flooding to locate the content. It is no longer app licable due to massive information available upfron t in the P2P systems. Sometime, it may not be even possible to return sma ll percent of relevant content for a search if it is an unpopular content. In this paper, we present adaptive semantic P2P conten t indexed system. Content indices are generated using topical semantics of documents derived using Wordnet ontology. Similarit ies between document hierarchies are computed using information theoretic approach. It enables locating and retriev al of contents with minimum document movement, sear ch space and nodes to be searched. Results illustrate that our work ca n achieve results better than Content Addressable N etwork (CAN) semantic P2P Information Retrieval (IR) system. Contrary to CAN semantic P2P IR system, we have used content aw are and node aware bootstrapping instead of random bootstrapping of search process.
