Instructions for Camera-Ready Papers

Disclaimer

ACM is revising its Publication Workflow and Article Templates for the article submission and publication process. As part of this process, ACM is switching to a single-column manuscript and a camera-ready version format. The purpose of the updated process is to increase the accessibility of articles published in the ACM Digital Library.

The following instructions will help you in formatting the camera-ready version of your RecSys paper. Please, read all of them carefully before submitting it. This flowchart summarizes all steps required to complete this process.

1. General Tips
  1. Have you completed the ACM eRights review form for your submission? As RecSys 2020 will be online only, we remind the authors that the location information on the copyright block text should be defined as “Virtual Event, Brazil”. Additionally, we emphasize that authors should agree to videotaping in the eRights form to attend virtually the conference. If you have not received an email from until a week before your camera-ready submission deadline, check the contact author(s)’s junk or spam email folders and complete the form promptly. If the eRights review form can not be located, email with your Paper ID number, title, and correct contact author’s valid email address.
  2. All submissions must comply with the ACM SIG proceedings templates and formatting.
  3. Be sure that all 3rd party material is properly documented. Please review the copyright policy.
  4. If you have questions or problems, please contact the proceedings co-chairs at the following email address:
  5. After completing the eRights form, you will receive an email from with a link through which you can access TAPS. Have you received this email? If not, check the contact author(s)’s junk or spam email folders. If the access link can not be located, email with your Paper ID number, title, and correct contact author’s valid email address.
  6. Submit your paper to The ACM Publishing System (TAPS) using the link sent to you by email.
2. Submission Deadlines

The submission deadlines for the production of the proceedings are:

  • Long Paper: August 10th

1. ACM Templates

Your camera-ready submission must be formatted according to the new standard ACM SIG proceedings format. The new format is available here. Further, the authors are required to include a proper classification for the paper according to the ACM Classification System (CCS). Additional information on how to use it is available here.

3.1 Word Template
3.2 LaTeX instructions
4. Page Limits

The following page limits refer to the single-column format required for camera-ready versions:

  • Long Paper: 14 pages plus 2 extra pages for references
  • Short Paper: 7 pages plus 2 extra pages for references
  • Reproducibility: 14 pages plus 2 extra pages for references
  • Doctoral Symposium: 7 pages plus 2 extra pages for references
  • Demo Papers: 3 pages plus 1 extra page for references
  • Tutorial Summaries: 4 pages plus 1 extra page for references
  • Workshop Summaries: 7 pages plus 2 extra pages for references
  • Challenge Summaries: 7 pages plus 2 extra pages for references
  • Industry Talks: 2 pages plus 1 extra page for references
  • Late-breaking results: 7 pages plus 2 extra pages for references
5. Paper Metadata
  • Double-check that your title and abstract fields in the TAPS submission page match the text in your paper.
  • Be sure that the title is in Initial Caps. Initial Caps Meaning First Letter of the Main Words Should be Made Capital Letters. Capitalize the First Letter of Main Words in the Title (Most Nouns), except a, an, the, conjunctions (and, but, or, for, …), and prepositions (of, to, in, on, …)
  • Double-check the author’s name, affiliation, and email in the paper.
6. Camera-Ready Submission

You should submit a single ZIP file containing ALL your source files (e.g., *.tex, *.bib, *.sty, and all figures for Latex Users or the .docx file for Word users). In order to upload these files into TAPS, follow the instructions presented in the ‘Final Submission and TAPS Author Workflow’ video tutorial.

The contact author will receive the ‘Notification to upload your paper to the ACM TAPS’ email from TAPS, in which the system will ask you to submit your source files and provide a unique link through which you can access TAPS (your specific author dashboard). In the top of your author dashboard TAPS provides the information about “Proceeding Acronym”, “Paper ID” and “Title of Paper”. You can upload a zip file in TAPS for further processing and the ZIP file naming should be like .zip. It is important to follow strictly all the instructions of file structure and naming of the zip file that should be uploaded on TAPS.

The publishing system produces automatically the traditional PDF output as well as ACM’s new responsive HTML5 design. Within 24 hours after submitting the .zip file, the contact author will receive the ‘PDF and HTML Proofs: available for review’ email notifying that the proofs for the published versions of your paper (both PDF and HTML5 versions) are available for your review and approval. Note that TAPS will generate the output PDF using the double-column format, which follows the “sigconf” proceedings template. TAPS receives the information from ACM’s system regarding which composition layout needs to be followed for the papers in your proceedings (i.e., “sigconf” in this case) and applies the required style internally.

If you are satisfied with the proofs for the published versions, please notify us of your approval within The ACM Publishing System (TAPS). If you find that the PDF and/or HTML file(s) did not convert correctly, follow the instructions presented in the author dashboard.

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

7. Page Limits for PDF Proof of Published Versions

After submitting your source files to TAPS, it will send to you HTML and PDF proofs for the published version, which should be approved by you. The PDF proof will be formatted in double-column, following the sigconf style. As one of the steps for approval, you should check whether the total number of pages of this PDF is in conformance with the page limits listed below, which refer to the double-column format produced by TAPS. It is expected that TAPS will automatically generate a version fitting these page limits. In case your final version ends up slightly over the limit, please work on figure flotation or on the usage of ‘vspace’ directives in Latex versions. In case of issues going through this process, please contact the proceedings co-chairs at the email address: .

  • Long Paper: 10 pages, including references
  • Short Paper: 6 pages, including references
  • Reproducibility: 10 pages, including references
  • Doctoral Symposium: 6 pages, including references
  • Demo Papers: 3 pages, including references
  • Tutorial Summaries: 3 pages, including references
  • Workshop Summaries: 6 pages, including references
  • Challenge Summaries: 6 pages, including references
  • Industry Talks: 2 pages, including references
  • Late-breaking results: 6 pages, including references
8. Publication in the Proceedings

In order to include your paper in the proceedings of the 14th RecSys and to schedule your presentation in the conference program, at least one of the authors MUST register for the conference by the firm deadline of August 20th. Further, at least one author MUST attend the conference to present the work. Make sure to use your institutional email address when registering (the same email address used in your paper). This will help us showcase speaker profiles alongside their paper in the conference platform.
