PROPOR 2026: 17th International Conference on Computational Processing of Portuguese.
Salvador - Bahia April 13th to 16th 2026

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 the automated language processing, promoting the development of methodologies, resources, and projects that can be shared among researchers and practitioners in the field.

We call for papers describing work on any topic related to computational language and speech 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 including Portuguese/Galician

PROPOR 2026 will be held from April 13th to April 16th at Salvador - BA, Brazil, the place of contact between the Portuguese language with both indigenous languages of Brazil and the African languages brought to Brazil with the enslaved people coming from Africa, a contact that deeply influenced Brazilian Portuguese and culture.

PROPOR 2026 will be the 17th edition of the biannual PROPOR conference, hosted alternately in Brazil and Portugal. 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 (2024)

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. That is, they should not contain the authors' names and affiliations. 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. Submissions should be written in English. 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
• MS Word stylesheet

The URL for paper submission will be announced soon
