Call for Contributions

Call for Papers

We are pleased to invite you to contribute to the Twelfth ACM Conference on Recommender Systems (RecSys 2018), the premier venue for research and applications of recommendation technologies. The upcoming RecSys conference will be held in Vancouver, Canada, from October, 2nd to October 7th, 2018. The conference will continue RecSys’ practice of connecting the research and practitioner communities to exchange ideas, frame problems, and share solutions. All accepted papers will be published by ACM.

We construe recommender systems broadly, including applications ranging from e-commerce to social networking, and a wide variety of technologies ranging from collaborative filtering to knowledge-based reasoning or deep learning. We welcome new research on recommendation technologies coming from very diverse communities ranging from psychology to mathematics. In particular, we care as much about the underlying algorithms and systems as we care about the human and economic impact of these systems.

Topics of interest for RecSys 2018 include (but are not limited to):

  • Conversational recommender systems
  • Novel machine learning approaches to recommendation algorithms
  • Evaluation metrics and studies
  • Explanations and evidence
  • Algorithm scalability, performance, and implementations
  • Innovative/New applications
  • Voice, VR, and other novel interaction paradigms
  • Case studies of real-world implementations
  • Preference elicitation
  • Privacy and Security
  • Economic models and consequences of recommender systems
  • Personalisation
  • Social recommenders
  • User modelling

Authors will be asked to assign a selection of predefined custom tags to describe their paper in the submission system. Tags can be assigned to indicate algorithms, interfaces, automated or user-centric evaluations, for example. Reviewers will also report their expertise over these tags, and the information will be used in review assignments.

Paper Submission Categories

LONG PAPERS should report on substantial contributions of lasting value. The maximum length is 8 pages (plus up to 1 page references). Each accepted long paper will be included in the conference proceedings and presented in a plenary session as part of the main conference program. Each accepted long paper will also be allocated a presentation slot in a poster session to encourage discussion and follow up between authors and attendees.
We expect the review process to be highly selective: the acceptance rates for full papers in the past three years was slightly over 20%.

SHORT PAPERS typically discuss exciting new work that is not yet mature enough for a long paper. In particular, novel but significant proposals will be considered for acceptance to this category despite not having gone through sufficient experimental validation or lacking strong theoretical foundation. Applications of recommender systems to novel areas are especially welcome. The maximum length is 4 pages (plus up to 1 page references). Each accepted short paper will be included in the conference proceedings and presented in a poster session. The poster presentation may include a system demonstration. Selected short papers will be invited as oral presentations. Note that rejected long paper submissions will not be considered as short papers.

SIGCHI Submitter Agreement

RecSys 2018 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 organise and manage the reviewing process, and, if the submission is accepted, the publication and presentation process. Thus, anyone who submits to RecSys 2018 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 paper is accepted, I or one of my co-authors will attend the conference. Papers that are not presented at the conference by an author may be removed from the proceedings at the discretion of the program chairs.
Paper Format and Submission

All submissions and reviews will be handled electronically. RecSys 2018 submissions should be prepared according to the standard double-column ACM SIG proceedings format. Additional information about formatting and style files is available online. Papers must be submitted to PCS2 by 23:59, AoE (Anywhere on Earth) on May 7th, 2018 (link will be available soon). There will be no extensions to the submission deadline.

The peer review process is double-blind (i.e. anonymised). This means that all submissions must not include information identifying the authors or their organisation. Specifically, do not include the authors’ names and affiliations, anonymise citations to your previous work and avoid providing any other information that would allow to identify the authors, such as acknowledgments and funding.

Please take note that the official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of the conference. The official publication date affects the deadline for any patent filings related to published work.

Important Dates
  • Abstract submission deadline: April 30th, 2018
  • Paper submission deadline: May 7th, 2018
  • Author notification: July 9th, 2018
  • Camera-ready version deadline: August 6th, 2018

Deadlines refer to 23:59 (11:59pm) in the AoE (Anywhere on Earth) time zone.
