Scope

The 18th International Conference on Similarity Search and Applications (SISAP) is an annual forum for researchers and application developers in the area of similarity data management. It aims at the technological problems shared by numerous application domains, such as data mining, information retrieval, multimedia retrieval, computer vision, pattern recognition, computational biology, geography, biometrics, machine learning, and many others that make use of similarity search as a necessary supporting service. From its roots in metric indexing, SISAP has expanded to become the only international conference entirely devoted to all issues surrounding the theory, design, analysis, practice, and application of content-based and feature-based similarity search.

SISAP is recognized as a CORE Rank B conference since 2021.

The conference proceedings will be published by Springer as a volume in the Springer Lecture Notes in Computer Science (LNCS) series.

Paper Submissions

We welcome two categories of papers:

• Full Papers (9–14 pages): Detailed technical contributions.
• Short Papers (up to 8 pages): Innovative ideas, early results, demonstration, vision or position papers.

All submissions will be peer-reviewed through a double-blind review process and must be properly anonymized. The Best Paper Award will be recognized with a certificate and a monetary prize sponsored by Springer.

Special Sessions

In addition to regular sessions, SISAP 2025 will feature two focused special sessions:

• IRMC: Interactive Retrieval for Multimedia Collections
  Exploring user-centric interfaces, relevance feedback mechanisms, and interactive search paradigms to enhance multimedia retrieval experiences.
