摘要

This collection of articles corresponds to papers selected from the Fifth International Workshop on Similarity Search and Applications (SISAP). 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. Four types of contributions are welcome: (1) fundamental techniques to handle general similarity search problems, (2) applied techniques to solve particular similarity search problems of wide interest, (3) new similarity search problems, where their features and challenges are studied, and (4) actual systems for similarity search, in the form of demos.
