We are pleased to invite you to contribute to the 15th ACM Conference on Recommender Systems (RecSys 2021), the premier venue for research on the foundations and applications of recommendation technologies. The upcoming RecSys conference will be held from September 27 to October 1, 2021. The conference will be held in Amsterdam, Netherlands, with an inclusive format that accommodates remote attendance. The conference will continue RecSys’ practice of connecting the research and practitioner communities to exchange ideas, frame problems, and share solutions.

The Late-Breaking Results (LBR) track of RecSys offers an opportunity for presenting new, interesting, preliminary results and speculative or innovative work in progress. The track seeks novel contributions that should be published immediately, because they will influence the work of others. The topics listed in the main track call for papers serve as a reference, but we also encourage submissions with clear relevance to recommender systems that extend this list.

Accepted contributions for this track will be presented as posters, where the informal setting encourages presenters and participants to engage in lively discussions about the presented work. All submissions should convey a scientific result or work in progress that is not yet ready to be published as a research paper at a refereed conference, but the preliminary results are already interesting.

Accepted submissions will be published as extended abstracts in the ACM RecSys 2021 conference proceedings.

SUBMISSION GUIDELINES

Submissions should report on substantial contributions of lasting value. The maximum length is 7 pages (excluding references) in the new single-column format.

All submissions and reviews will be handled electronically. Submissions must be submitted to PCS by 23:59, AoE (Anywhere on Earth) on July 13, 2021.

In addition to these guidelines, the guidelines in the main-track call for papers apply for Formatting, Anonymity, Ethical Review for Human-Subjects Research, Originality, Plagiarism and Patenting. Please make sure that you have read and understood those.

SIGCHI SUBMITTER AGREEMENT

RecSys 2021 is a SIGCHI conference and making a submission to a SIGCHI conference is a serious matter. Submissions require time and effort by SIGCHI volunteers to organize and manage the reviewing process, and, if the submission is accepted, the publication and presentation process. Thus, anyone who submits to RecSys 2021 implicitly confirms the following statements:

1. I confirm that this submission is the work of myself and my co-authors.
2. I confirm that I or my co-authors hold copyright to the content, and have obtained appropriate permissions for any portions of the content that are copyrighted by others.
3. I confirm that any research reported in this submission involving human subjects has gone through the appropriate approval process at my institution.
4. I confirm that if this submission is accepted, I or one of my co-authors will present it at the conference, either in person or through a conference-designated remote presentation option. Papers that are not presented at the conference by an author may be removed from the proceedings at the discretion of the program chairs.
