** 33rd International Symposium on String Processing and Information Retrieval** **October 13-16, Hamilton, Canada** **Second call for papers** The International Symposium on String Processing and Information Retrieval (SPIRE 2026) will be held at McMaster University, in Hamilton, Canada. Website: https://sites.google.com/view/spire-2026/ # SCOPE SPIRE 2026 covers research in all aspects of string processing, information retrieval, computational biology, and related applications. Typical topics of interest include (but are not limited to): - String Processing: String pattern matching, text indexing, data structures for string processing, text compression, compressed data structures, compressed string processing, text mining, 2D pattern matching, automata-based string processing, combinatorics on words. - Computational Biology: Algorithms for DNA sequencing, assembly, alignments, read error correction, metagenomics, transcriptomics, gene and regulatory element recognition, motif finding, pangenomics, variants discovery, phylogenetics, genome rearrangements. - Information Retrieval: Retrieval models and ranking, theoretical models and foundations of IR, efficiency and scalability topics in IR, knowledge acquisition in IR, machine learning and natural language processing for IR, knowledge representation and reasoning for IR, user-centric aspects of IR, IR evaluation, fairness, accountability, transparency in IR, domain-specific IR applications, web search. # SUBMISSIONS SPIRE 2026 invites submissions in two categories: - Long papers: Up to 12 pages, excluding references and optional appendices. - Short papers: Up to 6 pages, excluding references and optional appendices. Papers should be submitted electronically via EasyChair via the following link: https://easychair.org/conferences/?conf=spire2026 As in past editions, the proceedings of SPIRE 2026 will be published by Springer in the Lecture Notes in Computer Science (LNCS) series. The use of LNCS templates is mandatory. Suitable templates are available at the Springer Website and on Overleaf. Use the LNCS style file as given: do not change the margin size or the font; do not make a separate title page, etc. Simultaneous submissions to other conferences with published proceedings is not permitted. At least one author per accepted paper is expected to register for the conference and present the paper. The conference will be in-person, with online presentations only in exceptional cases (e.g., authors with travel difficulties). # AWARDS The SPIRE 2026 Conference will present both a Best Paper Award and a Best Student Paper Award, each sponsored by Springer Nature for 500 euros, to recognize outstanding research contributions. # INVITED SPEAKERS Meng He, Dalhousie University, Canada Lila Kari, University of Waterloo, Canada Tomasz Kociumaka, Max Planck Institute for Informatics, Germany # IMPORTANT DATES Submission deadlines: - Abstract Deadline: June 18, 2026 AoE - Full paper deadline: June 25, 2026 AoE (firm deadline) Notifications: August 6, 2026 Camera-ready version: August 20, 2026 Events: - SPIRE: October 13 to 15, 2026 - Workshop on Compression, Text, and Algorithms (WCTA): October 16, 2026 # GENERAL CHAIRS Neerja Mhaskar, McMaster University, Canada Ricardo Baeza-Yates, KTH Royal Institute of Technology, Sweden & University of Chile # PROGRAM COMMITTEE CHAIRS Neerja Mhaskar, McMaster University, Canada Solon P.
