4º International Conference on SImilarity Search and APplications (SISAP 2011)
June 30 – July 1, 2011, Lipari, Italy

Welcome
to the Web site for the 2011 SISAP Conference, to be held in Lipari, Italy, on June 30 – July 1, 2011. The annual International Conference on Similarity Search and Applications (SISAP) is a conference devoted to similarity searching, with emphasis on metric space searching. It aims to fill in the gap left by the various scientific venues devoted to similarity searching in spaces with coordinates, by providing a common forum for theoreticians and practitioners around the problem of similarity searching in general spaces (metric and non-metric) or using distance-based (as opposed to coordinate-based) techniques in general.
SISAP is at its fourth edition and aims to become an ideal forum to exchange real-world, challenging and exciting examples of applications, new indexing techniques, common testbeds and benchmarks, source code, and up-to-date literature through a web page serving the similarity searching community. Authors are expected to use the testbeds and code from the SISAP web site for comparing new applications, databases, indexes and algorithms.

A small selection of best papers will be recommended for inclusion in a special issue of Information Systems (Elsevier) dedicated to this conference. SISAP 2011 is organized in cooperation with ACM SIGSPATIAL and the papers are indexed in the ACM Digital Library.
