STIL
17th Symposium on Information Technology and Human Language
ABOUT
The Symposium on Information Technology and Human Language (STIL) is the most important event in Brazil for researchers interested in publishing significant and innovative results related to Natural Language Processing (NLP), in general (and not only in Portuguese). Since 2023, STIL has been held annually with the support of the Brazilian Computer Society (SBC) and the Special Interest Group on NLP (CE-PLN). In 2026, the 17th STIL will be held in Cuiabá, MT, Brazil, jointly with BRACIS 2026 (36th Brazilian Conference on Intelligent Systems), ENIAC 2026 (22nd National Meeting on Artificial and Computational Intelligence), and KDMILE 2026 (14th Symposium on Knowledge Discovery, Mining and Learning).
STIL 2026 consists of a main event and two sub-events: the XI Workshop on the Description of Portuguese (JDP 2026) and the XI Undergraduate Research Workshop on Information Technology and Human Language (TILic 2026). The symposium is multidisciplinary and covers several areas related to human language technology, such as Linguistics, Computer Science, Psycholinguistics, and Information Science, bringing together participants from academia and industry.

PAPER SUBMISSION GUIDELINES
Paper Types
STIL 2026 accepts submissions of long and short papers, as follows:
Long papers
Should describe completed, original, and unpublished work with significant results and will be presented orally.
Short papers
May report work in progress, negative results, opinion papers, or applications/demonstrations, and will be presented as posters.
Language
Papers may be written either in Portuguese, English, or Spanish.
Length
The length of the papers is defined as follows:
Long papers
Up to 10 pages of content (including tables and figures), with unlimited references.
Short papers
Up to 6 pages of content, with unlimited references.
Authors should indicate whether they accept that a long paper be presented as a poster, if so recommended by the reviewers. Submissions must include a Limitations section, Ethics Statement, and a disclosure of generative AI usage (extra page allowed).
Format
Papers must follow the SBC format, available on the SBC website and also on Overleaf.
Publication
Accepted papers will be published in the SBC Digital Library (SOL – SBC OpenLib) and in the ACL Anthology, and indexed in DBLP, ensuring wide visibility and international dissemination of the scientific production presented at the event.
Review
All papers submitted to STIL will be evaluated by at least two experts in the field
The review process will be double-blinded, therefore papers must not contain any information revealing the identity of the authors, either in the header or in the body of the text.
Self-citations that may reveal the authors' identity should be avoided. For example, instead of writing "As we previously showed (Silva, 2005)…", authors should write "Silva (2005) showed that …".
Review Policy
All authors of each submitted paper MUST serve as reviewers, IF they meet at least one of the following criteria:
- Hold a PhD degree or equivalent.
- Have at least three published papers in the NLP area.
- Have previously published in STIL.
Submission Policy
By submitting a paper to STIL 2026, the authors agree that at least one of them will register for the conference and present the work if it is accepted.
Registration must be completed before the camera-ready deadline and in the category defined by the organization.
Authors cannot be added to a paper after it has been accepted. The list of authors provided at the time of submission must be considered final. In exceptional cases where a paper includes more than 10 authors, authors are requested to contact the Program Chairs via email at the time of submission, as JEMS does not support more than 10 authors.
Anonymity Period
The following rules and guidelines aim to protect the integrity of the double-blinded review process and ensure fair evaluation of submissions.
The rules refer to the anonymity period, which runs from one month before the submission deadline until the acceptance or rejection notification.
Papers withdrawn during this period are no longer subject to these rules.
- During the anonymity period, it is not allowed to publicly release a non-anonymous version of the paper (for example, on preprint servers). Versions include papers with essentially the same scientific content, even if with minor differences (title, structure, or length).
- You may submit an anonymous version to the conference if a non-anonymous version was published online before the start of the anonymity period. The submitted version must not reference the non-anonymous version, and the program chairs must be informed of its existence.
- The non-anonymous version must not be updated during the anonymity period, and authors are asked not to promote it on social media or take other actions that could compromise the double-blinded review process.
- It is allowed to make an anonymous version of the paper publicly available (for example, on OpenReview or arXiv), even during the anonymity period.
Note: Although it is not forbidden to publish a non-anonymous version before the anonymity period begins, doing so makes maintaining double-blinded review more difficult. For this reason, it is recommended to wait until the end of the anonymity period before making it public.
Submission System
Long and short papers must be submitted in PDF format through the JEMS system https://jems3.sbc.org.br/stil2026/ up to the defined deadlines.
