****************************** PROPOR 2026: 17th International Conference on Computational Processing of Portuguese
Salvador - BA, Brazil
April 13th to 16th 2026
CALL FOR PAPERS
******************************
The International Conference on 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 very 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 call for papers 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 Sao Tome and Principe) -
Multilingual studies, methods, applications, and resources, Portuguese and/or Galician
PROPOR 2026 will take place from April 13th to 16th in Salvador - BA (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 from Africa. This linguistic and cultural contact profoundly shaped 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).
Submissions
Submissions should describe original, unpublished work. Authors are invited to submit two kinds of papers:
-
Full papers reporting substantial and completed work, especially those that may contribute in a significant way to the advancement of the area. Wherever appropriate, concrete evaluation results should be included. Full papers can have up to 8 content pages + 2 pages for references.
-
Short papers reporting small, focused contributions such as ongoing work, position papers, potential ideas to be discussed, 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 reviewing will be double-blind, submitted papers must be anonymized. Submissions should not include the 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 …”. Separate author identification information will be required as part of 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 final versions, authors of accepted papers will be given 1 extra content page to incorporate 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 conform to the ACL style guidelines and use the LaTeX or MS Word stylesheets below:
LaTeX stylesheet https://github.com/acl-org/acl-style-files/tree/master/latex
MS Word stylesheet https://github.com/acl-org/acl-style-files/tree/master/word
Papers should be submitted via the following URL https://cmt3.research.microsoft.com/PROPOR2026 by either selecting the track
PROPOR2026 Long and short papers.
Multiple-submission policy
For submissions that have been or will be submitted to other meetings or publications, this information must be provided at submission time. If a submission is accepted, authors must notify the program chairs, indicating which meeting they choose for presentation of their work. Papers that will be (or have been) published elsewhere cannot be accepted for publication or presentation.
Mandatory Reviewing Workload
As the pace of research in the field continues to increase, we need to strengthen the commitment to reviewing for each paper submission. During the submission process, authors will be required to specify which co-authors are committing to cover reviewing in the event.
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:
