The ACM Conference on Recommender Systems (RecSys) is the premier international forum for presenting new research results, systems, and techniques in the broad field of recommender systems. RecSys brings together leading international research groups and industry experts, including many of the world’s top companies in e-commerce and related domains. It is the most important annual event for the discussion and advancement of recommender systems research.

RecSys 2025, the nineteenth conference in this series, will be held in Prague, Czech Republic. It will bring together researchers and practitioners from academia and industry to present their latest findings and identify new trends and challenges in providing recommendation components across a range of innovative application contexts. In addition to the main technical track, the RecSys 2025 program will feature keynote and invited talks, tutorials on state-of-the-art topics, workshops, an industrial track, and a doctoral symposium.

    Statement on Inclusion and Safety

    As the organizers of RecSys 2025, we are committed to providing an inclusive, safe, and respectful conference environment for all attendees. As we increasingly realize the impact of our community’s work on society, we appreciate now more than ever the importance of providing an inclusive and accessible conference that brings together a diverse recommender systems community.
    As an ACM conference, RecSys and its organizers, speakers, and attendees are bound by the ACM Policy Against Discrimination and Harassment, which applies to both the conference venue and social media. As organizers, this is a policy that we fully endorse.
    RecSys has made efforts over the last several years to be an accessible and inclusive community, across various perspectives, and we have sought throughout our planning of RecSys 2025 to continue and expand those efforts. The General Chairs (Maria Bielikova, Pavel Kordik, and Markus Schedl) welcome your input.

    Accessibility and Inclusion at RecSys. The RecSys conference values and cares about diversity, accessibility and inclusion. We have always been diverse in terms of disciplinary backgrounds (e.g. including both HCI- and data-focused work), professional affiliations (e.g. strong representation from both academia and industry), and application domains of our work. We are aware that members in our community may come from historically underrepresented groups, for which we wish to pro-actively encourage and support increased participation. To ensure the conference and its activities are accessible to all, we also explicitly seek to address the visible or invisible support needs members of our community may have.

    Publications and Presentations. RecSys hosts a variety of scientific discussions. Historically, we have prepared guidelines for accessible and inclusive presentations. We would like to emphasize that inclusive, safe and respectful addressing does not only apply to conference presentations, but also to the whole process leading towards these presentations, including the way in which research is presented and reviewed. We therefore would like to encourage our community members to already keep our best practice guidelines on inclusive language in mind, when preparing their manuscripts and peer reviewing.

    Contact. Should you experience or witness a violation of the anti-harassment policy, or have any other concerns regarding your ability to fully and safely participate in the conference, please email the RecSys General Chairs; you can also directly reach them at the conference venue.

    We hope you have an amazing RecSys.

    Maria Bielikova, Pavel Kordik, and Markus Schedl
