- Henrik Nottelmann, K. Aberer, Jamie Callan, W. Nejdl. 2005. Proceedings of the 2005 ACM workshop on Information retrieval in peer-to-peer networks, P2PIR '05, Bremen, Germany, November 4, 2005. Abstract: It is our great pleasure to welcome you to the 2th Workshop on Information Retrieval in Peer-to-Peer Networks -- P2PIR 2005. This year's workshop aims at bringing together young researchers from Information Retrieval and Database Systems working on peer-to-peer information systems. Both communities have their own strategies at solving the problem of efficient and effective query routing in peer-to-peer networks, and a closer collaboration could have a large impact on future P2PIR research. As such, this proposed workshop continues the efforts from an SIGIR workshop last year on the same topic, and the primary goal is to foster the collaboration process started there.The call for papers attracted 15 submissions from Asia, Canada, the United States, Australia and Europe. The program committee accepted 6 papers that cover a variety of topics, including query routing, clustering and browsing, queries over RDF data and weighting schemes for peer-to-peer networks. In addition, the program includes two discussion sessions in order to benefit from different views in the two research communities. One discussion session will deal with problems and potential solutions in evaluating large-scale peer-to-peer networks, the other one about algorithmic and methodological problems.
