Distributed Information Systems Laboratory LSIR

Description

The goal of this research is to realize a Web retrieval engine using a P2P architecture. This aims at providing a richer set of retrieval mechanisms allowing to tailor more targetted and personalized Web search engines, providing more recent retrieval results and scaling with semantic complexity. We are addressing both link-based and text-based ranking methods. For link-based ranking we proposed and evaluated algebraic methods for decentralized computation of link-based rankings [1][4][6][7][8]. We addressed the problem of how to utilize rankings derived from Web structure and navigation [2][3]. Current efforts address the efficient implementation of text retrieval mechanisms in a decentralized architecture and integration in a P2P architecture [5][9].
