Dear all, The ACM Conference on Recommender Systems (RecSys) is soliciting submissions for its reproducibility track. The conference will take place in Prague, September 22-26, and the reproducibility track is complementary to the regular full and short tracks. All details can be found here: https://recsys.acm.org/recsys25/call/reproducibility. We encourage the submission of different types of papers, including: * Reproducibility and Replicability papers, that analyze prior works in different contexts, such as across different domains, using different datasets, or comparing against alternative baselines. * Resource papers that lay the foundation for future reproducibility, for example, by introducing new datasets or open-source software frameworks for evaluating recommender systems. * Methodology papers that propose, for example, novel offline evaluation protocols for reproducibility tasks or provide validated measurement scales for user-centric evaluations of recommendations. * Reflective works such as guidelines for reproducibility, surveys on reproducibility levels, or theoretical insights into research methodologies. Important dates: * Abstract submission deadline: May 6, 2025 * Paper submission deadline: May 13, 2025 * Author rebuttal period focused on the paper artifacts: June 5-10, 2025 * Author Notification: July 3, 2025 * Camera-ready version deadline: July 21, 2025 More information is available here: https://recsys.acm.org/recsys25/call/reproducibility. Kind regards, Alain Starke Publicity Co-Chair ACM RecSys 2025
