Abstract
This report presents the activities conducted within task T4.3 of the SAPIR project. It discusses the state-of-the-art of caching techniques in peer-to-peer (P2P) information systems. Caching is widely used in information systems to achieve better performance and high throughput. When moving to large scale distributed information systems, exploiting caching and replication becomes a must in order to overcome network costs and improve response times. Since caching in P2P information retrieval systems is still a quite young field of research, we also describe fundamental research in traditional and parallel web search engines and their possible extension to a large scale P2P environment like the one addressed by the SAPIR project. We also explore caching opportunities in metric spaces in order to support similarity search for multimedia objects exploited in SAPIR. To the best of our knowledge, no approach for caching in metric spaces was proposed so far.
