Call for Papers

29th ACM International Conference on User Modeling, Adaptation and Personalization
Theme: “Re-Evaluating Evaluation in Personalization Research”
Hybrid: Utrecht (The Netherlands) and Online
June 21-25th (tentative), 2021

Abstracts due: January 17, 2021 (mandatory)
Full paper due: January 24, 2021


ACM UMAP – User Modeling, Adaptation and Personalization – is the premier international conference for researchers and practitioners working on systems that adapt to individual users or to groups of users, and that collect, represent, and model user information. ACM UMAP is sponsored by ACM SIGCHI and SIGWEB, and organized with User Modeling Inc. as the core Steering Committee, extended with past years’ chairs. The proceedings are published by ACM and will be part of the ACM Digital Library.

ACM UMAP covers a wide variety of research areas where personalization and adaptation may be applied. This includes a number of domains in which researchers are engendering significant innovations based on advances in user modeling and adaptation, recommender systems, adaptive educational systems, intelligent user interfaces, e-commerce, advertising, digital humanities, social networks, personalized health, entertainment, and many more.

We welcome submissions related to user modeling, personalization and adaptation; the conference web site provides a detailed list. Below we present a short (but not proscriptive) list of topics of importance to the conference. As the theme for UMAP 2021 is “Re-Evaluating Evaluation” we encourage submissions in all areas that offer a critical analysis of evaluations of personalized systems. We particularly want to acknowledge that some of the research might be influenced by Covid-19 related constraints (e.g., difficulty of running lab studies), and welcome submissions which introduce novel methodologies arising from a need to conduct research in new ways.


We welcome submissions related to user modeling, personalization and adaptation in any area. The topics listed below are not intended to limit possible contributions.
Final decisions will be made on the basis of suitability for, and fit to, the overall conference (not for specific tracks). Additionally, there is no quota for the maximal number of accepted papers per track. Topics include (but are not limited to):

  • Personalized Recommender Systems
    Track chairs: Alejandro Bellogin, Sole Pera, Ludovico Boratto
  • Adaptive Hypermedia and the Semantic Web
    Track chairs: Maria Bielikova, Panagiotis Germanakos, Ben Steichen
  • Intelligent User Interfaces
    Track chairs: Katrien Verbert, Dennis Parra
  • Personalized Social Web
    Track chairs: Julita Vassileva, Jie Zhang
  • Technology-Enhanced Adaptive Learning
    Track chairs: Ella Haig, Manolis Mavrikis
  • Fairness, Transparency, Accountability, and Privacy
    Track chairs: Christine Bauer, Michael Ekstrand
  • Personalization for Persuasive and Behavior Change Systems
    Track chairs: Jaap Ham, Rita Orji


Papers will be submitted through EasyChair:

Long (8 pages + references) and Short (4 pages + references) papers in ACM style. Original research papers addressing the theory and/or practice of UMAP, and papers showcasing innovative use of UMAP and exploring the benefits and challenges of applying UMAP technology in real-life applications and contexts are welcome.

  • LONG PAPERS should present original reports of substantive new research techniques, findings, and applications of UMAP. They should place the work within the field and clearly indicate its innovative aspects. Research procedures and technical methods should be presented in sufficient detail to ensure scrutiny and reproducibility. Results should be clearly communicated and implications of the contributions/findings for UMAP and beyond should be explicitly discussed.
  • SHORT PAPERS should present original and highly promising research or applications. Merit will be assessed in terms of originality and importance rather than maturity, extensive technical validation, and user studies. Separation of long and short papers will be strictly enforced so papers will not compete across categories, but only within each category.

Papers must be formatted using the ACM SIG Standard (SIGCONF) proceedings template:

UMAP uses a double blind review process. Authors must omit their names and affiliations from submissions, and avoid obvious identifying statements. For instance, citations to the authors’ own prior work should be made in the third-person.

All accepted papers will be published by ACM and will be available via the ACM Digital Library. To be included in the Proceedings, at least one author of each accepted paper must register for the conference and present the paper there. Student registration fee is allowed for students who present a student paper.
