We are pleased to invite you to contribute to the 14th ACM Conference on Recommender Systems (RecSys 2020), the premier venue for research and applications of recommendation technologies. The upcoming RecSys conference will be held online, from September 22nd to September 26th, 2020. 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 invite submissions on all aspects of recommender systems, 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 human and economic impact of these systems as we care about their underlying algorithms.
Topics of interest for RecSys 2020 include but are not limited to (alphabetically ordered):
Algorithm scalability, performance, and implementations
Bias, fairness, bubbles and ethics of recommender systems
Case studies of real-world implementations
Context-aware recommender systems
Conversational recommender systems (e.g., conversational interaction, spoken language interfaces, dialogue systems)
Cross-domain recommendation
Economic models and consequences of recommender systems
Evaluation metrics and studies
Explanations and evidence
Innovative/New applications
Interfaces for recommender systems
Novel machine learning approaches to recommendation algorithms
Preference elicitation
Privacy and security
Social recommenders
User modelling
User studies
Voice, VR, and other novel interaction paradigms
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.
Submission Guidelines
All submissions and reviews will be handled electronically. Papers must be submitted to PCS by 23:59, AoE (Anywhere on Earth) on May 4th, 2020June 1st, 2020.
Formatting
Updated instructions for preparing camera-ready versions of accepted papers can be found here.
ACM is changing the archive format of its publications to separate content from presentation in the new Digital Library, enhance accessibility, and improve the flexibility and resiliency of our publications. Following the new 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 Master 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.
A document with some frequently asked questions can be found here.
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.
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 double-blind (i.e. anonymized). This means that all submissions must not include information identifying the authors or their organization. Specifically, do not include the authors’ names and affiliations, anonymize citations to your previous work and avoid providing any other information that would allow to identify the authors, such as acknowledgments and funding. 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.
Originality
Each paper should not be previously published or accepted to any peer-reviewed journal or conference/workshop, nor currently under review elsewhere (including as another paper submission for RecSys 2020). We generally discourage authors to submit the same paper to institutional or other preprint repositories such as arXiv.org before the reviewing process is complete, because it will place anonymity at risk. Please refer to the ACM Publishing License Agreement and Authorship Policy for further details.
Plagiarism
Plagiarized papers will not be accepted for RecSys 2020. Our committees will be checking the plagiarism level of all submitted papers to ensure content originality using an automated tool. Hence, authors are advised in their own interest to use a similar tool (e.g., iThenticate, Turnitin, Viper, PlagScan, etc.) to check the plagiarism level of their manuscripts before submission. The originality report generated by the tool may also be submitted at the time of paper submission.
Papers violating any of the above guidelines are subject to rejection without review.
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.
Paper Submission Categories
Long papers should report on substantial contributions of lasting value. The maximum length is 14 pages (excluding references) in the new single-column format. 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 rate for full papers in the past few years was about 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 into 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 7 pages (excluding references) in the new single-column format. 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 may be invited as oral presentations. Note that rejected long paper submissions will not be considered as short papers.
SIGCHI Submitter Agreement
RecSys 2020 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 2020 implicitly confirms the following statements:
I confirm that this submission is the work of myself and my co-authors.
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.
I confirm that any research reported in this submission involving human subjects has gone through the appropriate approval process at my institution.
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.
Important Dates
Abstract submission deadline: April 27th, 2020May 25th, 2020
Paper submission deadline: May 4th, 2020June 1st, 2020
Author notification: July 6th, 2020July 22nd, 2020
Camera-ready version deadline: July 27th, 2020August 10th, 2020
Deadlines refer to 23:59 (11:59pm) in the AoE (Anywhere on Earth) time zone.

Call for Reproducibility Papers
RecSys also strongly encourages the submission of algorithmic papers that repeat and analyze prior work. We distinguish between:
replicability papers, which repeat prior experiments using the original source code and datasets to show how, why, and when the methods work (or not); and
reproducibility papers, which repeat prior experiments, preferably using the original source code, in new contexts (e.g., different application domains and datasets, different evaluation methodologies and metrics) to further generalize and validate (or not) previous work.
Submissions regarding replicability or reproducibility papers are welcome in all areas related to recommender systems (see the main track Call for Papers for a list of topics).
In both replicability and reproducibility papers, we expect authors to provide all materials required for repeating the tests performed, including code, data, and clear instructions on how to run the experiments. Submissions from the same authors of the reproduced experiments will not be accepted.
Each accepted paper will be included in the conference proceedings and presented in a plenary session as part of the main conference program. Each accepted paper will also be allocated a presentation slot in a poster session to encourage discussion and follow-up between authors and attendees.
Review Criteria
Both replicability and reproducibility papers will be evaluated along the following criteria:
Novelty
What is new about the reproduced experiments?
Was the original work not supported from the theoretical point of view?
Were the original experiments not clear about important points or lacking confirmation for some of the original claims?
(Reproducibility papers only): Do the reproduced experiments bring more solid conclusions, with new datasets and metrics, with unbiased evaluation setups?
(Reproducibility papers only): Are there new experiments that allow for a better understanding of the impact of previous results?
Impact
How important is the reproduction of the experiments to the community?
How obvious are the conclusions achieved?
Do the reproduced prior works, if validated, advance a central topic to recommender systems (a topic with a broad applicability or focused on a hot research area)?
Reliability
Is the evaluation methodology in line with the research challenges addressed by the reproduced experiment?
Are the selected baselines representative of the several algorithm types and techniques available?
Is the hyperparameter tuning strategy properly described?
Are algorithms and baselines properly tuned?
Availability
Are the code and datasets used to reproduce the experiments available to the reviewers at the time of review?
Is the shared material released in a permanent repository for easy access by researchers?
Are the reproduced experiments well documented, with all the details required for other researchers to reproduce the experiments, as well?
Are there discrepancies between what is described in the paper and what is available in the shared material?
Is the shared material complete with everything you need to exactly replicate the experiments?

RecSys 2020 is pleased to 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. Tutorials focus on specific topics including, but not limited to:
Introductions to specific recommender systems techniques (e.g., deep learning, feature engineering, tensorflow)
Evaluation of recommender systems (e.g., system-centric and user-centric evaluation, experimentation)
Context-aware (including location-based) recommender systems
Designing user experiences and interactions (e.g., virtual assistants, chatbots, etc.)
Using different types of data (semantic web, graphs) and media (text, images, video, speech) for building recommendations
Ethical and legal aspects of recommender systems (e.g., privacy, fairness, accountability, transparency, and control of bias)
Recommender systems facing real-world challenges (e.g., large-scale recommender systems or stream-based recommendation)
Building and deploying recommender systems in specific domains (e.g., music, tourism, education, TV/video, jobs, enterprise, health, fashion)
Recommender systems supporting decision making
Recommendation for groups, tasks, or situations, including intent-aware recommender systems
Eliciting and learning user preferences
Recommender systems that take users’ emotional state, physical state, personality, trust, level of expertise, and/or cognitive readiness into account
Sensors and recommender systems (including mobile recommender systems and wearables)
Intersections of recommender systems with other domains (e.g., information retrieval, machine learning, human computer interaction, or databases)
Recommender systems in new domains, such as e-government, smart cities and energy
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 may work with accepted tutorial presenters to adjust the length of the tutorial, considering that tutorials may use up to two 90-minute slots, i.e. the length of the tutorials will be either 90 or 180 minutes.
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.
Submission Guidelines
All submissions and reviews will be handled electronically. Tutorial proposals must be submitted to PCS by 23:59, AoE (Anywhere on Earth) on May 25th, 2020June 8th, 2020.

Call for Workshop Proposals
RecSys 2020 is pleased to invite proposals for workshops to be held in conjunction with the conference. The goal of the workshops is to provide additional venues for discussing novel ideas as well as recent results of research in progress.
In 2020 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 in advance 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. Please contact us at least three weeks before the deadline.
We actively encourage both researchers and industry practitioners to submit workshop proposals.
Submission Guidelines
All submissions and reviews will be handled electronically. Workshop proposals must be submitted to PCS by 23:59, AoE (Anywhere on Earth) on March 2nd, 2020.

The ACM RecSys 2020 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 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:
Provide a supportive setting for feedback on students’ current research and guidance on future research directions.
Offer each student comments and fresh perspectives on their work from faculty and students outside their own institution.
Promote the development of a supportive community of scholars and a spirit of collaborative research.
Contribute to the conference goals through interaction with other researchers and conference events.
Student participants will have their extended abstracts published 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 ACM RecSys 2020 conference.
The format of the symposium will be primarily student presentations supplemented by one or two panel sessions to provide advice and Q&A opportunities with senior researchers in the field. Student presentations will be structured to provide maximum feedback. In particular:
Presentations will be limited to 15 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:
An extended abstract (see below).
A curriculum vitae.
A one-paragraph statement of expected benefits of participation, including questions regarding your dissertation that you would like to ask your symposium mentors.
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 PCS by 23:59, AoE (Anywhere on Earth) on May 18th, 2020June 15th, 2020.
Extended Abstract
Your extended abstract will be evaluated with regard to:
Originality of the work with respect to current concepts and techniques (provide relevant citations).
Importance of the work with respect to fundamental issues in recommender systems (clearly identify the problems you are trying to solve).
Rigor and validity of claims, argumentation, methodology, results, and interpretations.
Clarity and persuasiveness of expression.
Please write your extended abstract to the same quality standards as a regular RecSys submission.
Formatting
Updated instructions for preparing camera-ready versions of accepted papers can be found here.
ACM is changing the archive format of its publications to separate content from presentation in the new Digital Library, enhance accessibility, and improve the flexibility and resiliency of our publications.

Accepted extended abstracts will be later submitted to ACM’s new production platform where authors will be able to review PDF and HTML output formats before publication.
Confidentiality
Confidentiality of submissions is maintained during the review process. 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
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.
Application Checklist
Well in advance of the deadline:
Write an extended abstract according to the formatting instructions above. The maximum length for extended abstracts is 7 pages (excluding 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.
Write a curriculum vitae.
Write a one-paragraph statement of expected benefits of participation.
Obtain a letter of recommendation from your advisor.
By the deadline (May 18th, 2020, June 15th, 2020, 23:59 AoE):
Submit items 1-4 above in a single PDF file to PCS.

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 developers from small start-ups to large industries to present new recommender ideas and get valuable feedback from the recommender systems community.
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 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
Accepted demonstrations will be published in the conference proceedings. Authors will also be required to present a poster of their work at the conference.
Submission Guidelines
All submissions and reviews will be handled electronically. Demonstrations must be submitted to PCS by 23:59, AoE (Anywhere on Earth) on June 8thJune 22nd, 2020.

ACM is changing the archive format of its publications to separate content from presentation in the new Digital Library, enhance accessibility, and improve the flexibility and resiliency of our publications. Following the new ACM publication workflow, all authors should submit manuscripts for review in a single-column format. The maximum length for extended abstracts is 3 pages (excluding references) in the new single-column format. Instructions for Word and LaTeX authors are given below:
Microsoft Word: Write your submission 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 Master 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.
Should you have any questions or issues going through the instructions above, please contact support at for both LaTeX and Microsoft Word inquiries.
Accepted demonstrations 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
The description of the 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. (This section will be removed for the camera-ready version of accepted contributions.)
Anonymity
All submissions will be single-blind peer reviewed. This means that submissions should include information identifying the authors and their organization.
Originality
Demos must not be under review in any other conference at the time of submission and must contain novel contributions.
Important Dates
Demo submission deadline: June 8th, 2020June 22nd, 2020

Call for Late-Breaking Results
The Late-Breaking Results (LBR) track of RecSys offers an opportunity for presenting new, preliminary results and speculative or innovative work in progress, having the topics of interest of the regular call for papers as a main reference. 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 full-length research paper at a refereed conference, but the preliminary results are already interesting.
Accepted submissions will be published in the conference proceedings. Authors will also be required to present a poster of their work at the conference.
Submission Guidelines
All submissions and reviews will be handled electronically. LBR contributions must be submitted to PCS by 23:59, AoE (Anywhere on Earth) on July 13th, 2020July 27th, 2020.
