We are pleased to invite you to contribute to the Eleventh ACM Conference on Recommender Systems (RecSys 2017), the premier venue for research and applications of recommendation technologies. The upcoming RecSys conference will be held in Como, Italy, from August, 27th to August 31st, 2017. The conference will continue RecSys’ practice of connecting the research and practitioner communities to exchange ideas, frame problems, and share solutions. All the accepted papers will be published by ACM.
We construe recommender systems broadly, including applications ranging from e-commerce to social networking, platforms from web to mobile and beyond, and a wide variety of technologies ranging from collaborative filtering to knowledge-based reasoning. Topics of interest for RecSys 2017 include (but are not limited to):
Algorithm scalability
Case studies of real-world implementations
Conversational recommender systems
Context-aware recommenders
Evaluation metrics and studies
Explanations and evidence
Field and user studies
Group recommenders
Innovative/New applications
Machine learning for recommendation
Mobile and multi-channel recommendations
Novel paradigms
Personalisation
Preference elicitation
Privacy and Security
Recommendation algorithms
Social recommenders
Semantic technologies for recommendation
Trust and reputation
Theoretical foundations
User interaction and interfaces
User modelling
The authors will be asked to indicate whether their paper is primarily Algorithm or Application focussed. Algorithm papers should discuss novel algorithmic approaches to recommendation challenges, with appropriate evaluations and comparisons to baseline works. Application papers should discuss new domains or large-scale applications of recommenders or focus on user experience, interface, or impact. This will allow the PC Chairs to better assign reviewers and to balance the program.
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. We expect the review process to be highly selective: the acceptance rates for full papers in the past three years were 20-24%.
SHORT PAPERS typically discuss exciting new work that is not yet mature enough for a long paper. 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 plenary session as part of the main conference. The presentation may include a system demonstration. Note that rejected long paper submissions will not be considered as short papers.
SIGCHI Submitter Agreement
RecSys 2017 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 2017 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.
Paper Format and Submission
All submissions and reviews will be handled electronically. RecSys 2017 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 EasyChair by 23:59, AoE (Anywhere on Earth) on April 3rd, 2017. 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.

RecSys 2017 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 are 90-minute intensive instructional sessions that focus on specific topics including, but not limited to:
Introductions to recommender systems or to specific techniques (e.g., collaborative filtering, visual/audio content analysis, or deep learning),
Evaluation of recommender systems (system-centric or user-centric evaluation),
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, and/or well-being),
Designing user experiences,
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),
Ethical and legal aspects of recommender systems, including fairness, accountability, transparency and control of bias,
Intersections of recommender systems with other domains (e.g., information retrieval, machine learning, human computer interaction, or databases).
We actively encourage both researchers and industry practitioners to submit tutorial proposals that target different levels of expertise and different interests.
Proposal Format and Submission
The tutorial proposal should be a PDF document no more than 2 pages long, submitted by e-mail to and organized as follows:
Tutorial title.
Name, email address, and affiliation of tutorial instructor(s). Each listed presenter 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.
Importance of the topic for the RecSys community.
Teaching experiences and history of prior tutorials by the presenter(s).
List of relevant publications by the presenter(s).
The following elements are not mandatory for the proposal, but encouraged:

Call for Workshop Proposals
RecSys 2017 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 2017 our goal is to have a balanced workshop program which comprises workshop formats of different types and a combination of emerging and established topics. Different full-day and half-day workshop formats are possible, for example:
Novel interactive workshop formats with a correspondingly 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. Particular priority will be given to these formats which require the active involvement of the participants.
Traditional mini-conferences on specialized topics; such workshops typically have their own paper submission and review processes. Proposals for continuations of existing workshop series are welcome; a brief statement on the development of the workshop series, e.g., in terms of topics, number of paper submissions and participants or post-workshop publications over the years should be provided.
Mini-competitions or challenges around selected topics with individual or team participation are also highly welcome.
We encourage you to contact us 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.
We encourage both researchers and industry practitioners to submit proposals.
Proposal Format and Submission
The workshop proposal should be a PDF document no more than 4 pages long, submitted by e-mail to and organized as follows:
Workshop title
A short description of workshop including the rationale for the workshop and how and why it fits the audience of RecSys. This description should include also the topic, format, and details about what type of submission is requested from prospective attendees.
Name, email address, and affiliation for workshop chair(s) and a brief description of their experience in organizing such events.
Requested duration (half day or full day), and expected number of participants.
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 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.
History of prior workshops on this topic, if any.

The ACM Recommender Systems 2017 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 they would benefit from this kind of feedback on their work to apply for this unique opportunity to share their work with students in a similar situation as well as senior researchers in the field. The strongest candidates will be those have made some progress, but who are not so far along their research that they can no longer make changes. 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 (4 pages excluding references) published in the conference proceedings. They will also have the opportunity to present a poster of their work during the poster session at the main conference.
Doctoral symposium participants will be provided complimentary registration for the symposium and will receive additional travel support for the 2017 ACM Summer School on Recommender Systems and the ACM RecSys 2017 conference directly from the ACM.
Symposium Format and Participation Expectations
The doctoral symposium will be operated in conjunction with the 2017 ACM Summer School on Recommender Systems held at the Free University of Bozen-Bolzano, Bozen-Bolzano, Italy. The symposium will run all day on Friday, August 25th, culminating with a group dinner.
Itinerary
August 21st-25th, 2017: Summer school (Bozen-Bolzano, Italy)
August 25th, 2017: Doctoral symposium (Bozen-Bolzano, Italy)
August 26th, 2017: Travel day
August 27th-31st, 2017: RecSys conference (Como, Italy)
At the Symposium
Participants are expected to attend the entire symposium, including the dinner, and are also expected to attend the ACM RecSys 2017 conference. Symposium participants will be welcome to participate in the 2017 ACM Summer School on Recommender Systems, however they need to register. Accepted participants will receive travel support for the 2017 ACM Summer School on Recommender Systems and the RecSys 2017 conference directly from the ACM.
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 20 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, you will also present your 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.
Application Format and Submission
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.
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.
Submit these three items in a single PDF file to . Your contribution should be named lastname_ds.pdf, where lastname is your family name. The file must be no larger than 5 Mbytes.
A brief letter of recommendation from your doctoral advisor or mentor focused on how your participation in the doctoral symposium will benefit your dissertation research.
Your doctoral advisor should send this letter directly to us at .
Extended Abstract
Prepare a four-page (excluding references) extended abstract of your thesis work in the two-column ACM SIG Proceedings Format. The 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. The accepted extended abstracts will be published in the conference proceedings and available in the ACM Digital library, where they will remain accessible to thousands of researchers and practitioners worldwide.
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 to no more than 8 doctoral students. 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.

The demo session provides an exciting way for researchers and developers to present new recommender ideas, show off their work, and get valuable feedback from the recommender systems community.
We invite demonstrations of developments in 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 experiments (showing something new to RecSys attendees could be a valuable source of data on user interaction with your recommender concept)
Recommendation platforms
RecSys demos provide innovators and researchers a unique opportunity to get feedback from the recommender systems community on their ideas. RecSys has an excellent history of being well-attended by industry representatives — past conferences have had attendees and presenters from Netflix, Amazon, Google, Facebook, LinkedIn, Criteo, Pandora, Twitter, Ebay, IBM, etc. The blend of industry and academic attention provides an excellent environment to demonstrate and discuss your latest invention or idea. Taking advantage of this environment, the demo track is particularly useful for several groups:
Researchers wanting to allow attendees to interact with their work, not just see it presented, and possibly gather usage data for feedback
Deployed recommender systems available to interact with
Early stage start-ups looking to showcase their ideas and gain feedback and exposure
Submissions
Demos should be submitted in a single PDF file through the EasyChair system and must include the following, in order:
A two-page demo summary that includes a link to a narrated screen capture of your system in action (ideally a video). This two-page summary of accepted demos will be published in the conference proceedings. For a formatting template, please see here.
A one-page description of the demonstrated system and 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. The description should also provide information about the presenter(s), including their relationship to the project.
Note: At least one of the authors of each accepted demo is required to attend the conference.
Important Dates
Demo submission deadline: May 31st, 2017
Demo notification: June 16th, 2017
Camera-ready demo summary deadline: July 7th, 2017
Deadlines refer to 23:59 (11:59pm) in the AoE (Anywhere on Earth) time zone.
The poster session offers an opportunity for presenting late-breaking research results and speculative or innovative work in progress. The informal setting of the poster session 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.
Submissions
Posters should be submitted in PDF format through the EasyChair system. The submission shall consist of a two-page poster summary describing the late-breaking research. For a formatting template, please see here. The two-page summary of accepted posters will be included in separate CEUR proceedings (see proceedings for Recsys 2016 and RecSys 2015 Posters).
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 own previous work and avoid providing any other information that would allow to identify the authors, such as acknowledgments and funding.
In addition to the two-page submission, accepted poster authors will be asked to create a poster to be displayed at the conference in a dedicated poster area, and present their work during the poster session.
Note: At least one of the authors of each accepted poster is required to attend the conference.
Important Dates
Poster submission deadline: June 19th, 2017
