P2P Distributed Information Retrieval Method by the Independent Indices Management for the Ubiquitous Services Environment

Abstract

In this paper, we propose and discuss the distributed information retrieval (IR) manner named the independent indices management manner for contents and services on the overlay networks. The proposal manner has two features; one is un-structured indices management model which generates and manages the indices independently on each management peers selected from overlay networks, and another is the connections based on the P2P technology. The result of evaluations clarifies our proposal manner has both abilities: the peer distribution scalability as same as P2P overlay network applications, and retrieval accuracy as same as indices centralized in a server manner. Comparing with our previous work, our proposal manner in this paper is suitable in view points of distribution scalability, load balancing, and fault tolerance. As last, we could expect that our proposal is used as one of distributed IR manners for the ubiquitous services environments.
