Workshop on Online Misinformation- and Harm-Aware Recommender Systems

Co-located with RecSys 2020


September, 25th - Rio de Janeiro, Brazil

Types of submissions

We will consider five different submission types, all following the new single-column format ACM proceedings format (following the LaTeX or Word template): regular (max 14 pages), short (between 4-8 pages), and extended abstracts (max 2 pages), excluding references. Authors of long and short papers will also be asked to present a poster.


  • Research papers (regular or short) should be clearly placed with respect to the state of the art and state the contribution of the proposal in the domain of application, even if presenting preliminary results. Papers should describe the methodology in detail, experiments should be repeatable, and a comparison with the existing approaches in the literature should be made where possible.

  • Position papers (regular or short) should introduce novel points of view in the workshop topics or summarize the experience of a researcher or a group in the field.

  • Practice and experience reports (short) should present in detail the real-world scenarios that present harmaware recommender systems. 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.

  • Dataset descriptions (short) should introduce new public data collections that could be used to explore or develop harm-aware recommender systems.

  • Demo proposals (extended abstract or poster) should present the details of a prototype recommender system, to be demonstrated to the workshop attendees.

Submission will be accepted through Easychair.


Each submitted paper will be refereed by three members of the Program Committee, based on its novelty, technical quality, potential impact, insightfulness, depth, clarity, and reproducibility.

In order to generate a strong outcome of the workshop, all long and short accepted papers will be included in the Workshop proceedings, provided that at least one of the authors attends the workshop to present the work. Proceedings will be published in a volume, indexed on Scopus and DBLP (tentatively, CEUR).
