Call for Papers
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)
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.
Ethics Policy
Authors are advised to follow the ACL Ethics Policy for submission, which can be found here
Authors are also strongly advised to follow the ACL guidelines for generative AI assistance in authorship, which can be found here
Important Dates
- Full and short paper submission deadline: Dec 7th (23:59 GMT-12)
Nov 16th, 2025 (23:59 GMT-12) - Notification of paper acceptance or rejection: Feb 02nd, 2026
- Camera-ready papers due: Mar 27th, 2026

- 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. 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.
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.

CALL FOR WORKSHOP PROPOSALS
The overall purpose of a workshop is to provide participants with the opportunity to present and discuss novel research ideas on active and emerging topics of computational processing of Portuguese, Galician and their variants.
Workshops can take on several forms including (but not limited to) being organized around emerging research areas, challenge problems and industrial applications. The organizers of approved workshops are required to announce the workshop and call for papers, gather submissions, conduct the reviewing process and decide upon the final workshop program. They must also prepare a set of workshop proceedings in an electronic version. They may choose to form organizing or program committees for assistance in these tasks.
The workshop organizers are responsible for:
- Creating and distributing call-for-papers, call-for-participation and any other relevant advertising. The calls should make it clear that at least one author of any accepted paper must attend the event and that papers will be withdrawn if no such participation is secured with the payment of the workshop dues. The call should clearly describe the review and selection process. Finally, the calls must be framed to encourage as broad a participation as possible.
- Creating and publishing (on time) a website with all the relevant information about the workshop.
- Provide an extended abstract for the conference program.
- Review (at least two independent reviewers) and select the submitted papers.
- Schedule the presentations within the workshop.
- It should be noted that the conference organization does not budget for free registration, accommodation, or travel expenses for the workshop organizers or their invited speakers. The workshop organizers should therefore secure any source of funding/sponsorship deemed necessary for their invited speakers.
- Prepare electronic proceedings volumes by March 27 2026.
- Attend the workshop and select any required session chairs.

Salvador
Salvador, also known as São Salvador da Bahia de Todos os Santos (English: Savior; Saint Savior from the Bay of All Saints) is the capital of the Brazilian state of Bahia. With 2.9 million people (2017), it is the largest city proper in the Northeast Region and the 4th largest city proper in the country, after São Paulo, Rio de Janeiro and Brasília.
Founded by the Portuguese in 1549 as the first capital of Brazil, Salvador is one of the oldest colonial cities in the Americas. A sharp escarpment divides its Lower Town (Cidade Baixa) from its Upper Town (Cidade Alta) by some 85 meters (279 ft). The Elevador Lacerda, Brazil's first elevator, has connected the two since 1873. The Pelourinho district of the upper town, still home to many examples of Portuguese colonial architecture and historical monuments, was named a World Heritage Site by UNESCO in 1985.
Salvador was the first slave port in the Americas and the African influence of the slaves' descendants in many cultural aspects of the city makes it a center of Afro-Brazilian (negro) culture. The city is noted for its cuisine, music, dance and architecture. Porto da Barra Beach in Barra has been named one of the best beaches in the world. Itaipava Arena Fonte Nova was the site of the city's games during the 2014 Brazilian World Cup and 2013 Confederations Cup.
Salvador forms the heart of the Recôncavo, Bahia's rich agricultural and industrial maritime district, and continues to be a major Brazilian port. Its metropolitan area, housing 3 899 533 people (2018) forms the wealthiest one in Brazil's Northeast Region (2015).
The Deputado Luís Eduardo Magalhães Airport connects Salvador with all major Brazilian cities and also operates several international flights.
Conference Location
PROPOR 2026 will be held at Mercure Hotel located at Rio Vermelho, which is one of the most famous neighborhood in Salvador (Bahia - Brazil). Besides its wonderful beaches (Paciência and Buracão), this place is known by a high number of pubs and restaurants, making you comfortable to try the traditional cuisine and local culture from Salvador.
