PROPOR 2026: 17th International Conference on Computational Processing of Portuguese
Salvador - BA, Brazil
April 13th to 16th 2026
FINAL CALL FOR PAPERS (deadline extension: January 9)
********************************************************
The International Conference on the Computational Processing of Portuguese (PROPOR) is the main event in the area of human language processing that is focused on theoretical and technological issues of written and spoken Portuguese and Galician. The meeting has been a rich forum for the exchange of ideas and partnerships for the research and industry communities dedicated to automated language processing, promoting the development of methodologies, resources, and projects.
We invite submissions describing work on any topic related to the computational processing of Portuguese and Galician by researchers in industry or academia. Topics of interest include, but are not limited to:
-
Natural language processing tasks (e.g., parsing, word sense disambiguation, coreference resolution) -
Natural language processing applications (e.g., question answering, subtitling, summarization, sentiment analysis) -
Natural language generation -
Information extraction and information retrieval -
Speech technologies (e.g., spoken language generation, speech and speaker recognition, spoken language understanding) -
Speech applications (e.g., spoken language interfaces, dialogue systems, speech-to-speech translation) -
Resources, standardization, and evaluation (e.g., corpora, ontologies, lexicons, grammars) -
NLP-oriented linguistic description or theoretical analysis -
Distributional semantics and language modeling -
Portuguese language varieties and dialect processing (including the language varieties of Angola, Brazil, Cape Verde, East Timor, Galicia, Guinea-Bissau, Macau, Mozambique, Portugal, and São Tomé and Príncipe) -
Multilingual studies, methods, applications, and resources, Portuguese and/or Galician
PROPOR 2026 will take place from April 13-16th in Salvador, Bahia (Brazil), a city that stands as a historical meeting point between the Portuguese language, the Indigenous languages of Brazil, and the African languages brought by enslaved peoples.These long-standing linguistic and cultural interactions have been instrumental in shaping the evolution of Brazilian Portuguese and Brazilian culture.
PROPOR 2026 will be the 17th edition of the biannual PROPOR conference, hosted alternately in Brazil and Portugal, and more recently also in Galiza. Past meetings were held in Lisbon, PT (1993); Curitiba, BR (1996); Porto Alegre, BR (1998); Évora, PT (1999); Atibaia, BR (2000); Faro, PT (2003); Itatiaia, BR (2006); Aveiro, PT (2008); Porto Alegre, BR (2010); Coimbra, PT (2012); São Carlos, BR (2014); Tomar, PT (2016); Canela, BR (2018); Évora, PT (2020); Fortaleza, BR (2022); and Santiago de Compostela, GZ (2026).
*Important dates*
- Full and short paper submission deadline: *09/01/2026 * - Notification of paper acceptance or rejection: 11/02/2026 - Camera-ready papers due: 15/03/2026 - Conference: 13-16/04/2026
Submissions
Submissions should describe original and unpublished work. Authors are invited to submit two types of papers:
-
Full papers reporting substantial and completed research, particularly work that contributes significantly to the advancement of the field. Where appropriate, submissions should include concrete evaluation results. Full papers may be up to 8 pages of content + 2 additional pages for references. -
Short papers reporting small, focused contributions such as ongoing research, position papers, promising ideas for discussion, negative results, or an interesting application nugget. Short papers can have up to 4 content pages + 1 page for references.
Each submission will be evaluated by at least two reviewers. As the review process is double-blind, submitted papers must be fully anonymized. Submissions must not include authors’ names, affiliations, or any other information that could be used to identify them. Authors must avoid self-references that reveal identity, like “We previously showed (Freitas, 1991) …”. Instead, they should prefer citations such as “Freitas (1991) previously showed …”. Author information will be collected separately during the submission process.
While recent editions have only accepted submissions in English, this year we are pleased to also accept papers written in Portuguese, reaffirming our commitment to promoting scientific exchange in our language.
At submission time, only PDF format is accepted. For the camera-ready version, authors of accepted papers will be given 1 additional content page to address the reviews’ suggestions. Authors of accepted papers will be requested to send the source files for the production of the proceedings. All submitted papers must adhere to the ACL style guidelines and use the LaTeX template below:
- LaTeX stylesheet https://github.com/acl-org/acl-style-files/archive/refs/heads/master.zip - Overleaf Template https://www.overleaf.com/latex/templates/association-for-computational-linguistics-acl-conference/jvxskxpnznfj - Paper Formatting Guidelines https://acl-org.github.io/ACLPUB/formatting.html
Papers should be submitted via the following URL https://cmt3.research.microsoft.com/PROPOR2026 by selecting the track PROPOR2026 Long and short papers.
Multiple-submission policy
For work that has been or will be submitted to other venues, this information must be clearly indicated at submission time. If a paper is accepted, the authors must inform the Program Chairs of their final decision regarding the venue at which the work will be presented. Papers that are published (or scheduled for publication) elsewhere cannot be accepted for publication or presentation at PROPOR 2026.
*Mandatory Reviewing Workload *As the pace of research in the field continues to accelerate, it is essential to reinforce our collective commitment to the review process. Accordingly, during submission, authors will be required to indicate which co-authors commit to serving as reviewers for the conference.
Publication
The proceedings of PROPOR 2026 will be published in the ACL Anthology. They will be available online. To ensure publication, at least one author of each accepted paper must complete a full registration for PROPOR 2026 by the early registration deadline.
Ethics Policy
Authors are advised to follow the ACL Ethics Policy for submission, which can be found at: https://aclrollingreview.org/cfp#ethics-policy
Authors are also strongly advised to follow the ACL guidelines for generative AI assistance in authorship, which can be found at:
