Promoted by the Brazilian Computer Society (SBC), the Brazilian Symposium on Multimedia and Web (WebMedia) is the main event of the theme in Brazil and an excellent opportunity for scientific and technical exchange among students, researchers and professionals in the areas of Multimedia, Hypermedia and Web. This year we will be celebrating the 27th edition of WebMedia, which will be held on November 5th and 8th to 12th, 2021, organized by the Federal University of Minas Gerais and the Federal University of São João Del Rey. Like the 2020 edition, WebMedia 2021 will be held online, with interaction among participants using tools and web platforms.

We invite the research community to share research experiences and results by submitting technical papers that describe solutions to advance the state-of-the-art in multimedia, hypermedia and the Web. Submitted papers will be evaluated in terms of originality, technical quality, relevance, presentation (organization, style, and clarity) and adequacy of references to works in the state-of-the-art of the approached themes.

Each paper (full or short) will be revised by a minimum of three members of the Program Committee and invited specialists. The presentation of each accepted paper will be made using tools and platforms that allow interaction between the presenter and the WebMedia community by videoconference.


Authors may submit full or short papers. Full papers (up to 8 pages) shall report substantial research based on complete results. Short papers (up to 4 pages) may describe ongoing works, containing partial results.

Papers must present their main contribution in the areas of multimedia, hypermedia and the Web, and may be related, among others, to the following topics of interest:

– Accessibility
– Affective Computing
– AI, Machine Learning and Deep Learning
– Application Test and Validation
– Authoring and Annotation
– Content Adaptation and Personalization
– Content Characterization, Analysis, Search and Retrieval
– Context Awareness
– Crowdsourcing
– Data Mining
– Digital Health and Assistive Technologies

– Ontologies, Metadata and Semantic Web
– Security, Privacy, Fairness & Interpretability
– Standards and Technical Recommendations
– Recommender Systems
– Social Networks and Social Media
– Ubiquitous and Pervasive Computing
– User Experience and QoE
– Web Engineering

The papers can be written in Portuguese or English. Papers written in Portuguese should have both the title and abstract in English and, optionally, the abstract in Portuguese. This is a requirement of ACM, so even if it is an article in Portuguese, it must have a title and abstract in English.

Papers should be written to allow double-blind review. Thus authors’ identifications must be replaced by “removed for double-blind review” both at the beginning of the article and in any references to their previous work.

Authors are encouraged to review previous WebMedia publications to see if their theme fits the symposium’s lines of interest. Also, consider the pertinence of including references to related works presented in previous editions of WebMedia, to assist the reviewers in evaluating the contribution, in particular, in the scope of WebMedia.

The event proceedings, containing full and short articles, will be published in the ACM Digital Library. Only those articles whose authors comply with the deadlines established for submitting the final version to the publisher responsible for the proceedings will be published by ACM. Besides, this publication will be conditioned to the registration of at least one of its authors in the event.


Submissions should be made in PDF, following the standard ACM format that is available at ( Authors should use the LaTeX template for ACM conferences using the acmart class in the sigconf format.

All papers must be submitted electronically by the JEMS System


Submission dates can be found on the important dates page.
