Call for Contributions

Call for Reproducibility Papers

The reproducibility of empirical results is a cornerstone of scientific research and a prerequisite to ensure continuous progress in our field. ACM RecSys ‘23 therefore strongly encourages submissions which repeat or analyze prior works in similar or alternative settings or which contribute to an increased level of reproducibility in the future.

Types of papers

We encourage the submission of different types of papers, including:

• Reproducibility papers,which analyze prior works in different contexts, e.g., in different domains, with different datasets, compared to different baselines.
• Resource papers that provide the foundation for future reproducibility, e.g., in terms of new datasets or open-source software frameworks for the evaluation of recommender systems.
• Methodology papers, which for example propose novel offline evaluation protocols or provide validated measurement scales for user-centric evaluations of recommendations.
• Reflective works, such as guidelines for reproducibility, surveys of reproducibility levels, or theoretical reflections on our research methodology.

Other types of submissions related to the wider topic of reproducibility in recommender systems are welcome as well. Please reach out to the track chairs at in advance in case you are not sure if your work could be a match for the reproducibility track.

Submission and reviewing

Similar to the main track of ACM RecSys ‘23 the review process is double-blind. Submissions therefore must not include the author names and affiliations, and the code/data repositories should be set up to maintain anonymity as well.

We expect authors to provide all relevant materials that are needed to fully assess the validity of the submission. In case of reproducibility studies involving computational experiments, this would for example include all code, data, and installation instructions that are needed to re-execute the experiments that are reported in the paper.

Each paper will be reviewed by members of the programme committee of the track. The review criteria, among others, will include the following specific aspects:

• Novelty: What is new about the reported findings or insights?
• Impact: What is the expected impact of the reported findings or insights?
• Reliability: Is the work technically sound?
• Availability: Is the submitted work well documented and repeatable?

Each accepted paper will be included in the conference proceedings, and a selected number of papers will be presented in a plenary session as part of the main conference program. We encourage authors to create a companion website that hosts all relevant material.

Submission Guidelines

We accept long papers of up to 14 pages (excluding references) and short papers of up to 7 pages (excluding references) in ACM’s new single-column format, corresponding to the categories of the call for papers for the main track. The length of a submission should be commensurate with its contribution.

It is expected that at the time of submission, code and datasets used to reproduce the experiments will be available under reasonably liberal terms and sufficiently well-documented such that reviewers may consult that documentation as they conduct their reviews.

Submission System

Papers must be submitted via EasyChair at https://easychair.org/my/conference?conf=acmrecsys2023reprodu. Note that papers intended for the main track of ACM RecSys 2023 should be submitted to a different EasyChair installation.

Important Dates

• Abstract submission deadline: April 14th, 2023
• Paper submission deadline: April 21st, 2023
• Author notification: June 28th, 2023
• Camera-ready version deadline: July 26th, 2023

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

Paper Formatting

ACM’s archival publication format separates content from presentation in the Digital Library to enhance accessibility and improve the flexibility and resiliency of our publications. Following the ACM publication workflow, all authors should submit manuscripts for review in a single-column format. Instructions for Word and LaTeX authors are given below:

• Microsoft Word: Write your paper using the Submission Template (Review Submission Format). Follow the embedded instructions to apply the paragraph styles to your various text elements. The text is in single-column format at this stage and no additional formatting is required at this point.

• LaTeX: Please use the latest version of the Primary Article Template – LaTeX to create your submission. You must use the “manuscript” option with the \documentclass[manuscript, anonymous]{acmart} command to generate the output in a single-column format which is required for review. Please see the LaTeX documentation and ACM’s LaTeX best practices guide for further instructions. To ensure 100% compatibility with The ACM Publishing System (TAPS), please restrict the use of packages to the whitelist of approved LaTeX packages.

Authors are strongly encouraged to provide “alt text” (alternative text) for floats (images, tables, etc.) in their content so that readers with disabilities can be given descriptive information for these floats that are important to the work. The descriptive text will be displayed in place of a float if the float cannot be loaded. This benefits the author as well as it broadens the reader base for the author’s work. Moreover, the alt text provides in-depth float descriptions to search engine crawlers, which helps to properly index these floats. Additionally, authors should follow the ACM Accessibility Recommendations for Publishing in Color and SIG ACCESS guidelines on describing figures.

Should you have any questions or issues going through the instructions above, please contact support at for both LaTeX and Microsoft Word inquiries.

Accepted papers will be later submitted to ACM’s new production platform where authors will be able to review PDF and HTML output formats before publication.

Anonymity

The peer review process is mutually anonymous (double-blind). This means that all submissions must not include information identifying the authors or their organization. Specifically, do not include the authors’ names and affiliations, refer to your previous work in the third person (e.g., “Zhang and Di Noia (2023) recommended that RecSys submissions be anonymized by referring to the authors’ prior work in the third person.”), and avoid providing any other information that would allow reviewers to identify the authors, such as acknowledgments of individuals and funding sources. However, it is acceptable to explicitly refer in the paper to the companies or organizations that provided datasets, hosted experiments or deployed solutions if there is no implication that the authors are currently affiliated with the mentioned organization. Reviewers are instructed not to search for tech reports, pre-prints, and other information about your research. Your responsibility is focused on making sure that the paper submission itself does not reveal your identity as author.

Ethical Review for Human-Subjects Research

ACM RecSys expects all authors to comply with ethical and regulatory guidelines associated with human subjects research, including research involving human participants and research using personally identifiable data. Papers reporting on such human subjects research must include a statement identifying any regulatory review the research is subject to (and identifying the form of approval provided), or explaining the lack of required review. Reviewers will be asked to consider whether the research was conducted in compliance with applicable ethical and regulatory guidelines.

We encourage authors to consider further ethical implications and broader impacts of their work, and to discuss these in an appropriate section of their papers; “A Guide to Writing the NeurIPS Impact Statement” provides non-binding guidance on some of the kinds of things authors may wish to consider.

Originality

Each paper should not be previously published or accepted to any peer-reviewed journal or conference, nor currently under review elsewhere (including as another paper submission for RecSys 2023). Papers published in workshop proceedings may only be submitted if the RecSys submission includes at least 30% new content; such papers must also reference the original workshop paper on the submission form (but not in the anonymized paper).

Plagiarism

Plagiarized papers will not be accepted for RecSys 2023. Our committees will be checking the plagiarism level of all submitted papers to ensure content originality using an automated tool.

If you reuse non-novel text from a prior publication (e.g., the description of an algorithm or dataset), please be sure to cite the prior publication as the source of that text. If you have questions about reuse of text or simultaneous submission, please contact the program chairs at least one week prior to the submission deadline. Please refer to the ACM Publishing License Agreement and Authorship Policy for further details.

Papers violating any of the above guidelines are subject to rejection without review and cases may be referred to the ACM Publications Ethics and Plagiarism committee for further action where warranted.

Patenting

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.

SIGCHI Submitter Agreement

RecSys 2023 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 2023 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 present the paper 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.

Call for Tutorial Proposals

Submission deadline extended to June 2nd, 2023.

We are pleased to invite you to contribute to the 17th ACM Conference on Recommender Systems (RecSys 2023), the premier venue for research on the foundations and applications of recommendation technologies. The upcoming RecSys conference will be held from September 18th to September 22nd, 2023. The conference will be held in Singapore. The conference will continue RecSys’ practice of connecting the research and practitioner communities to exchange ideas, frame problems, and share solutions.

We invite proposals for tutorials to be given in conjunction with the conference. The goal of the tutorials is to provide conference attendees, including early-career researchers and researchers crossing over from related disciplines, with an opportunity to learn about recommender system concepts and techniques. Tutorials also serve as a venue to share presenters’ expertise with the global community of recommender system researchers and practitioners.

Each tutorial will provide an in-depth coverage of an established recommender systems subtopic, introduce an emerging application of recommendation technologies, or update the recommender systems community on recent advances in related fields. Relevant topics including but not limited to:

• Building and deploying recommender systems in specific domains (e.g., commerce, music, tourism, education, TV/video, jobs, enterprise, health, fashion, e-government, smart cities, energy, etc.);
• Introductions to specific recommender systems techniques (e.g., deep learning,
  feature engineering, graph models, reinforcement learning, conversational
  recommender systems, intelligent interactive recommendation, large scale
  recommender systems, stream based recommendation, etc.); Using different types of data (semantic web, graphs) and media (text, images, video, speech) for building
  recommendations;
• Intersections of recommender systems with other domains (generative models,
  information retrieval, machine learning, human computer interaction, databases,
  economics, psychology, etc)
• Designing user experiences and interactions with systems offering recommendation
  and intelligent interaction (e.g., virtual assistants, chatbots, robots, etc.); Eliciting and learning user preferences through interactions;
• Recommendation for groups, tasks, or situations; Context-aware (including location-based) recommender systems; Sensors and recommender systems (including mobile recommender systems and wearables); Recommender systems supporting decision making; Recommender systems in the Metaverse;
• Affective Recommender systems that take into account users’ emotional state, physical state, personality, trust, level of expertise, and/or cognitive readiness into account.
• Ethical and legal aspects of recommender systems (e.g., privacy, fairness, accountability, transparency, and control of bias, etc.);
• Evaluation of recommender systems (e.g., system-centric and user-centric evaluation, experimentation, etc.).

The length of your proposed tutorial should be commensurate with the presented materials and the projected interest of the RecSys community in the tutorial topic. We expect tutorial slots of either 90 or 180 minutes. We may work with accepted tutorial presenters to adjust the length of the tutorials for the available slots. Realize that you need to be flexible, since we may not be able to accommodate your favorite choice of date and time for the tutorial.

We actively encourage both researchers and industry practitioners to submit tutorial proposals that target different levels of expertise and different interests. We also encourage the submission of hands-on tutorials, for instance through the use of notebooks that combine theoretical concepts with practical exercises.

As a tutorial presenter, you are expected to write a short tutorial summary for the conference proceedings (detailed instructions will be provided), present your tutorial at the conference in person, and provide a link to your tutorial materials after the tutorial so that it can be posted on the ACM RecSys 2023 website and serve as a resource to the community.

If you submit a tutorial, please realize that you are expected to attend the physical conference and present your tutorial in person.

Submission Guidelines

All submissions and reviews will be handled electronically. Tutorial proposals must be submitted to  EasyChair  by 23:59, AoE (Anywhere on Earth) on 30 May 2 June 2023. The tutorial proposal should be organized as follows:

• Tutorial title.
• Tutorial length.
• Motivation for proposing this tutorial (why it is important for RecSys).
• Name, email address, and affiliation of tutorial instructors (each listed instructor must present in person at the conference).
• Detailed bulleted outline of the tutorial (this point should take the most space).
• Targeted audience (introductory, intermediate, advanced) and prerequisite knowledge or skills.
• Teaching experiences and history of prior tutorials by the presenters.
• List of relevant publications by the presenters.
• Main differences with tutorials on the same or similar topic (in past RecSys editions – please, specify the year – or other conferences).

The submission should be a .pdf file of about 2 pages in length (single column, no particular formatting required).

Note that it is possible that we issue a second call for late-breaking tutorial proposals, but please do not count on it. We would appreciate it if you would submit your proposal to this call.

EVALUATION CRITERIA

Tutorial proposals will be reviewed according to:

• the ability of the tutorial to contribute to strengthening the foundations of recommender system research, or to broaden the field to look at important new challenges and technique
• experience and skill of the presenters
• the value of any materials released with the tutorial for the community.

Important Dates

• Tutorial proposals due: 30 May 2 June, 2023
• Tutorial proposals notifications: 20 June 2023

Call for Workshop Proposals

We are pleased to invite you to contribute to the 17th ACM Conference on Recommender Systems (RecSys 2023), the premier venue for research on the foundations and applications of recommendation technologies. The upcoming RecSys conference will be held from September 18th to September 22nd 2023. The conference will continue RecSys’ practice of connecting the research and practitioner communities to exchange ideas, frame problems, and share solutions. RecSys 2023 is pleased to invite proposals for workshops to be held in conjunction with the conference, which will be held in Singapore, with both in-person and virtual workshops. The goal of the workshops is to provide additional venues for discussing novel ideas as well as recent results of research in progress.

In 2023, our goal is to have a balanced workshop program which comprises workshop formats of different types and a combination of newly emerging, currently evolving, and historically understudied topics. Different full-day and half-day workshop formats are possible, for example:

• Workshops with novel interactive formats and a relatively small number of participants. Such workshop formats might for example target at the exploration of a certain topic during the workshop through a moderated discussion or breakout sessions, resulting in a draft paper or report to be completed and published after the workshop. Or they might focus on datasets and benchmarking for a particular problem or domain. Particular priority will be given to these formats which require the active involvement of the participants.
• Workshops with the traditional workshop format on specialized topics. Such workshops typically have their own paper submission and review processes. Proposals for continuations of existing workshop series are welcome. However, please include a brief statement on the necessity for the new edition, including a description of the outcomes of previous years and the expected novelty of this edition.

We encourage you to contact us by email at up to two weeks before the deadline with workshop ideas; we will work with prospective workshop organizers to help them design successful proposals. In particular, for workshop proposals with novel interactive formats, we are happy to assist you in further developing and implementing your ideas. We actively encourage both researchers and industry practitioners to submit workshop proposals.

Submission Guidelines

All submissions and reviews will be handled electronically. The maximum length is 7 pages (excluding references) in the new single-column format. Workshop proposals must be submitted to EasyChair by 23:59, AoE (Anywhere on Earth) on March 9th, 2023.

Contents of the proposal

The workshop proposal should be organized as follows:

• Workshop title.
• A short description of the workshop, including the rationale for the workshop and how and why it fits the audience of RecSys. This description should also include the topic and its relevance to the community as well as format, and details about what type of submission is requested from prospective attendees. Please also add an explanation on how the workshop complements, rather than duplicates, the topics of the main conference.
• Name, email address, and affiliation for workshop organizers and a brief description of their experience in organizing such events. Note that organizers are expected to be actively involved in its organization, including attending the workshop whenever possible. Please, indicate the contact point for us to communicate effectively. In the case of more than four organizers, please justify the need for each contribution.
• Requested duration (half day or full day), with a motivation on the choice of this duration, and expected number of participants.
• Workshop format (virtual, in-person, or hybrid). Note that in-person workshops will require at least one organizer to attend;
• Description of workshop activities. Outline how the workshop will be organized and how the time will be spent. In particular, please sketch how you will engage participants to foster more interactivity and engagement during the workshop;
• For workshops involving paper submissions, an initial—and for the most part confirmed— Program Committee (or a clear justification why it is not needed);
• For more interactive workshop formats, also outline the process of selecting or inviting the participants;
• Description of plans for promoting the workshop and disseminating the results, for instance, by organizing a journal special issue with extended versions of the workshop’s best papers;
• History of prior workshops on this topic (if available), including URLs, a brief statement on the development of the workshop series, e.g., in terms of topics, #paper submissions and participants, post-workshop publications over the years, and acceptance statistics.

Call for Doctoral Symposium Submissions

Submission deadline extended to June 2nd, 2023.

The ACM RecSys 2023 Doctoral Symposium provides an opportunity for doctoral students to explore and develop their research interests under the guidance of a panel of distinguished researchers from both academia and industry. We invite students who feel that they would benefit from this kind of feedback on their work to apply for this unique opportunity, which will allow them to share their work with their peers as well as with senior researchers in the field. The strongest candidates will be those who have already made some research progress, but who are not so far along that they can no longer make changes in their research plans. Typically, this means that they have defined their topic and have completed some research, but still have at least a year of research remaining before completing a dissertation (in many universities this corresponds to the dissertation proposal stage). The feedback from attendees in previous years has been very positive and the Doctoral Symposium has been considered very useful in providing research guidance.

The symposium has the following objectives:

1. Provide a supportive setting for feedback on students’ current research and guidance on future research directions.
2. Offer each student feedback and fresh perspectives on their work from faculty and students outside their own institution.
3. Promote the development of a supportive community of researchers and a spirit of collaborative research.
4. Contribute to the conference goals through interaction with other researchers and conference events.

Student participants will have their extended abstracts included in the conference proceedings. They will also present a poster of their work at the conference.

Symposium Format and Participation Expectations

Participants are expected to attend the entire symposium, and are also expected to attend the RecSys 2023 conference. The RecSys conference will be held from September 18th-22nd, 2023, and the symposium will be held on September 18th, 2023. The conference as well as the symposium will take place in Singapore, with an inclusive format that accommodates remote attendance.

The format of the symposium will be primarily student presentations and Q&A opportunities with senior researchers in the field, supplemented by one or two panel sessions to provide advice.

Student presentations will be structured to provide maximum feedback. In particular:

• Presentations will be limited to 10 minutes, followed by 20-25 minutes for feedback and discussion.
• Two of the symposium faculty will be assigned to provide “primary” feedback for each presenter; following this primary feedback there will be a period of open feedback from all participants.
• Students will be expected to take notes for another participant so that each of you can focus on interacting during the discussion surrounding your presentation.
• During the main conference, students will also present their dissertation work and plans in the form of a poster presentation.
• Being accepted into the symposium is an honor, and involves a commitment to giving and receiving thoughtful commentary with an eye towards shaping the field and upcoming participants in the research area.

Submission Guidelines

Applications are invited from graduate students pursuing a PhD project who would benefit from detailed workshop discussions of their doctoral research by a panel of established researchers. All submissions and reviews will be handled electronically.

Application

Applications should include the following:

1. An extended abstract (see below).
2. A curriculum vitae or resumé.
3. A one-paragraph statement of expected benefits of participation, including questions regarding your dissertation that you would like to ask your symposium mentors.
4. A brief letter of recommendation from your doctoral advisor, focused on how your participation in the Doctoral Symposium will benefit your dissertation research.

Submit these four items in a single PDF file to EasyChair by 23:59, AoE (Anywhere on Earth) on May 23rd June 2nd, 2023.

Extended Abstract

The maximum length for extended abstracts is 8 pages (plus up to 2 pages of references) in the new single-column format. See below for formatting instructions and selection criteria. Note that the student is the sole author of the abstract. Advisor(s) can be thanked in the acknowledgments.

Please write your extended abstract to the same quality standards as a regular RecSys submission.

Formatting

ACM’s archival publication format separates content from presentation in the Digital Library to enhance accessibility and improve the flexibility and resiliency of our publications. Following the ACM publication workflow, all authors should submit manuscripts for review in a single-column format. Instructions for Word and LaTeX authors are given below:

Should you have any questions or issues going through the instructions above, please contact support at for both LaTeX and Microsoft Word inquiries.

Accepted papers will be later submitted to ACM’s production platform where authors will be able to review PDF and HTML output formats before publication.

Originality

Each paper should not be previously published or accepted to any peer-reviewed journal or conference, nor currently under review elsewhere (including as another paper submission for RecSys 2023). Papers published in workshop proceedings may only be submitted if the RecSys submission includes at least 30% substantially new approaches and results; such papers must also reference the original workshop paper in the submission form (but not in the anonymized paper).

Plagiarism

Plagiarized papers will not be accepted for RecSys 2023. Our committees will be checking the plagiarism level of all submitted papers to ensure content originality using an automated tool.
If you reuse non-novel text from a prior publication (e.g., the description of an algorithm or dataset), please make sure to cite the prior publication as the source of that text. If you have questions about reuse of text or simultaneous submission, please contact the program chairs at least one week prior to the submission deadline. Please refer to the ACM Publishing License Agreement and Authorship Policy for further details.
Papers violating any of the above guidelines are subject to rejection without review and cases may be referred to the ACM Publications Ethics and Plagiarism committee for further action where warranted.

Confidentiality

Confidentiality of submissions is maintained during the review process, where only the DS Chairs will have access to the submissions. All rejected submissions will be kept confidential in perpetuity. All submitted materials for accepted submissions will be kept confidential until two weeks prior to the start of the conference. Submissions should contain no information or materials that are proprietary at publication time.

Selection Criteria

Your extended abstract will be evaluated by the DS Chairs with regard to:

1. Originality of the work with respect to current concepts and techniques (provide relevant citations).
2. Importance of the work with respect to fundamental issues in recommender systems (clearly identify the problems you are trying to solve).
3. Rigor and validity of claims, argumentation, methodology, results, and interpretations.
4. Clarity and persuasiveness of expression.

To provide maximum feedback to each student, participation in the Doctoral Symposium is limited. Selection is based on two broad criteria:

• Value of the symposium to the student:
  • The degree to which the applicant is positioned to benefit from participation, including the student’s position in the doctoral process (the greatest benefit is for students with a developed research idea but much of the work yet undone).
  • The degree to which the student may otherwise lack access to a diverse set of feedback and input on his or her research plans (e.g., availability of local experts and advisors).
• Value of the student’s participation to other students:
  • The quality of the extended abstract (as identified above), both as a model of excellent research and as an indication of the student’s potential in the field.
  • Diversity of participation, including diversity by institution, country, research topic and approach, and demographics. In general we will limit participation to one or two students per institution, depending on the number of applicants.
  • Evidence that the student will be an effective and active participant, providing feedback to others and helping to build a research network (such as, e.g., prior experience in meetings, workshops, etc., or any feedback the advisor may provide on this).

Application Checklist

Well in advance of the deadline:

1. Write an extended abstract according to the formatting instructions above. The maximum length for extended abstracts is 8 pages (+ up to 2 pages references) in the new single-column format. Note that the student is the sole author of the abstract. Advisor(s) can be thanked in the acknowledgments.
2. Write a curriculum vitae.
3. Write a one-paragraph statement of expected benefits of participation.
4. Obtain a letter of recommendation from your advisor.

By the deadline (May 23rd June 2nd, 2023, 23:59 AoE): Submit items 1-4 above in a single PDF file to EasyChair.

Support

We very strongly advise students to also apply for a spot as a student volunteer (SV). Student volunteers will receive free registration to RecSys 2023. Students accepted for the Doctoral Symposium will be prioritized for a student volunteer spot. The deadline for SV applications is planned to be after the notifications for the Doctoral Symposium.

Regarding travel grants, students could apply for Gary Marsden Travel Awards (GMTA) established by SIGCHI to get support for attending the conference. Eligible members can be undergraduate and graduate students, early-career researchers (such as those who are ≤ 5 years post-graduation), and those suffering from financial hardship or lacking institutional support. You can apply even before having an accepted submission. (Still, GMTA “will prioritize first-time attendees and presenters”.) You can find detailed information on the Travel Grants page.

SIGCHI Submitter Agreement

RecSys 2023 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 2023 implicitly confirms the following statements:

1. I confirm that this submission is the work of myself.
2. I confirm that I 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 present the paper 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.

Call for Demonstrations

We are pleased to invite you to contribute to the 17th ACM Conference on Recommender Systems (RecSys 2023), the premier venue for research on the foundations and applications of recommendation technologies. The upcoming RecSys conference will be held from September 18–22, 2023 in Singapore, with an inclusive format that accommodates remote attendance. Each accepted contribution is expected to be presented in person. The conference will continue RecSys’ practice of connecting researchers, practitioners, and students to exchange ideas, frame problems, and share solutions across a range of specialties concerned with recommendation. All accepted papers will be published by ACM.

Demos show implementations of novel, interesting, and important recommender systems’ concepts or applications. Allowing potential users to see and use a demo of a research work makes them excited about it – it makes the work real and tangible. Demos also allow researchers from academia and developers from small start-ups to large industries to present new recommender ideas and get valuable feedback from the recommender systems community.

We welcome new demonstrations of recommendation technologies coming from diverse communities ranging from psychology to mathematics. In particular, we care as much about the human and economic impact of these systems as we care about their underlying algorithms.

The conference will continue RecSys’ practice of connecting the research and practitioner communities to exchange ideas, frame problems, and share solutions. RecSys has an excellent history of being well-attended by industry representatives — past conferences have had attendees and presenters from Netflix, Amazon, Booking, Google, Facebook, LinkedIn, Criteo, Pandora, Spotify, etc. The blend of industry and academic attention provides an excellent environment to demonstrate and discuss the latest inventions or ideas.

We invite demonstrations relevant to all aspects of recommender systems, including, but not limited to:

• Interaction techniques (preference elicitation interfaces, recommendation presentation, explanations, and more);
• Tools for development and analysis of recommender systems (design tools, evaluation systems, analytics tools);
• Innovative applications of recommender systems;
• Recommender user experiments;
• Recommender platforms;
• New code libraries for recommender systems.

Accepted demonstrations will be published in the conference proceedings as an extended abstract. Authors will also be required to present a poster of their work at the conference.

Reviewing Process

Reviewers will evaluate demos based on their significance, originality, and contribution to the field. In view of the RecSys conference goal of advancing the field, reviewers are also asked to consider the replicability of the reported research. Sharing of data sets and code is encouraged and will be part of the review process. Given the mixed conference format, the audio and video quality of the accompanying screencast will be evaluated.
Submissions that are out of scope, incomplete, or lack sufficient evidence to support the basic claims, may be rejected without full review.

Submission Guidelines

The description of a demo must include the following:

• An overview of the algorithm or system that is the core of the demo, including citations to any publications that support the work.
• A discussion of the purpose and the novelty of the demo.
• A description of the required setup. If the system will feature an installable component (e.g., mobile app) or website for users to use throughout or after the conference, please mention this.
• A link to a narrated screen capture of your system in action, ideally a video. The maximum duration of screen capture is 10 minutes. (This section will be removed for the camera-ready version of accepted contributions but might be included in the virtual platform used to host the online part of the conference.)
• We also highly encourage any external material related to the demo (e.g., shared code on GitHub). Please, provide a link to the shared code in the extended abstract accompanying the demo.

A demo submission should report on a description of the demo. The maximum length is 4 pages (excluding references) in the new single-column format.

All submissions and reviews will be handled electronically. Submissions must be submitted to easychair by 23:59, AoE (Anywhere on Earth) by July 3rd, 2023.

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.

Call for Late-Breaking Results

We are pleased to invite you to contribute to the 17th ACM Conference on Recommender Systems (RecSys 2023), the premier venue for research on the foundations and applications of recommendation technologies. The upcoming RecSys conference will be held from September 18–22, 2023 in Singapore, with an inclusive format that accommodates remote attendance. Each accepted contribution is expected to be presented in person. The conference will continue RecSys’ practice of connecting researchers, practitioners, and students to exchange ideas, frame problems, and share solutions across a range of specialties concerned with recommendation. All accepted papers will be published by ACM.

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 2023 conference proceedings.

Submission Guidelines

Submissions should report on new and preliminary contributions. 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 easychair by 23:59, AoE (Anywhere on Earth) by July 3rd, 2023.

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.

Call for Industry Talk Proposals

We are pleased to invite you to contribute to the 17th ACM Conference on Recommender Systems (RecSys 2023), the premier venue for research and applications of recommendation technologies. The upcoming RecSys conference will be held on September 18–22, 2023 in Singapore, with an inclusive format that accommodates remote attendance. The conference will continue RecSys’ practice of connecting researchers, practitioners, and students to exchange ideas, frame problems, and share solutions across a range of specialties concerned with recommendation.

Industry practitioners are invited to submit proposals to the RecSys industry track for a conference presentation. Although attendance to the conference may be remote, we expect presenters to be there in person. The industry track is focused on challenges and practical solutions to significant real-world issues faced by industry practitioners. We encourage submissions that describe substantial real-world challenges and novel deployed systems that power recommendations in commercial settings. This includes design and interaction aspects of recommender systems. We also recognize that diverse speaker backgrounds and topics facilitate richer discussions at the conference, therefore we especially encourage colleagues from backgrounds that are under-represented in the conference series to submit talk proposals.

All submissions will be reviewed for relevance to real-world challenges, novelty, and contribution to the community. Shared data sets and code are encouraged, as are insights into quantitative and/or qualitative evaluation results. However, industry-track submissions can focus on real-world, industry data and results, and as such the level of detail and evaluation is not required to be as deep as the main research track. Real-world impact and ethical considerations of the systems described will also be taken into account. Note that proposals consisting of sales pitches for products will not be considered.

Examples of talk topics include, but are not limited to:

• Lessons learned from real-world deployment of recommender systems including case studies, retrospectives, and user studies.
• Societal impact, fairness and bias of recommender systems in the real world.
• Novel recommender system applications.
• Novel techniques that solve significant issues in production deployment.
• Online and offline metrics used to evaluate recommender systems and studies of their interaction in production settings.
• Design and interaction aspects of recommender systems.
• Holistic overviews or component deep dives of recommender system pipelines including ETL, candidate generation, research and production training, feature stores and inference.
• Privacy preserving recommendation systems in production, e.g. using federated learning
• System and algorithm scalability and performance
• Challenges faced by practitioners that are under-studied in the research community or novel to particular recommendation applications.

Authors of the selected proposals will give an oral presentation in the Industry Track and be invited to present a poster at the conference poster sessions. Extended abstracts will also be published in the conference proceedings.

Submission Guidelines

All submissions and reviews will be handled electronically. Papers must be submitted to EasyChair by 23:59, AoE (Anywhere on Earth) on June 1st, 2023.
To allow for preparation of the conference’s online presence, we might request audiovisual material, such as a recording of the talk, two weeks before the conference start date.

Formatting

ACM’s archival publication format separates content from presentation in the Digital Library to enhance accessibility and improve the flexibility and resiliency of our publications. Following the ACM publication workflow, all authors should submit manuscripts for review in a single-column format. The maximum length for extended abstracts is 4 pages (including bios and excluding references) in the single-column format. Instructions for Word and LaTeX authors are given below:

• Microsoft Word: Write your proposal using the Submission Template (Review Submission Format). Follow the embedded instructions to apply the paragraph styles to your various text elements. The text is in single-column format at this stage and no additional formatting is required at this point.
• LaTeX: Please use the latest version of the Primary Article Template – LaTeX to create your submission. You must use the “manuscript” option with the \documentclass[manuscript]{acmart} command to generate the output in a single-column format which is required for review. Please see the LaTeX documentation and ACM’s LaTeX best practices guide for further instructions. To ensure 100% compatibility with The ACM Publishing System (TAPS), please restrict the use of packages to the whitelist of approved LaTeX packages.

Authors are strongly encouraged to provide “alt text” (alternative text) for floats (images, tables, etc.) in their content so that readers with disabilities can be given descriptive information for these floats that are important to the work. The descriptive text will be displayed in place of a float if the float cannot be loaded. This benefits the author as well as it broadens the reader base for the author’s work. Moreover, the alt text provides in-depth float descriptions to search engine crawlers, which helps to properly index these floats. Additionally, authors should follow the ACM Accessibility Recommendations for Publishing in Color and SIG ACCESS guidelines on describing figures.

Should you have any questions or issues going through the instructions above, please contact support at for both LaTeX and Microsoft Word inquiries.

Accepted proposals will be later submitted to ACM’s new production platform where authors will be able to review PDF and HTML output formats before publication.

Contents

Industry talk proposals must include the following:

• Title and abstract of the proposal presentation
• Short CV of the presenter(s) (up to 300 words)
