STIL 2025

The Symposium in Information and Human Language Technology (STIL) is the most important event in Brazil for researchers interested in publishing significant and novel results related to Natural Language Processing (NLP) in general (not only applied to Portuguese). Since 2023, STIL has been held as an annual event supported by the Brazilian Computer Society (SBC) and the Brazilian Special Interest Group on Natural Language Processing (CE-PLN).

In 2025, STIL will be held in Fortaleza, Ceará, Brazil, collocated with BRACIS 2025 (The 35th Brazilian Conference on Intelligent Systems), ENIAC 2025 (The 21th National Meeting on Artificial and Computational Intelligence), SBBD 2025 (40th Brazilian Symposiom on Databases) and KDMILE 2025 (The 13th Symposium on Knowledge Discovery, Mining and Learning).

STIL 2025 is composed of a main event and two sub-events, namely the X Portuguese Description Conference (JDP 2025) and the X Scientific Initiation Workshop in Information Technology and Human Language (TILic 2025).

The multidisciplinary conference covers a broad spectrum of disciplines related to Human Language Technology, such as Linguistics, Computer Science, Psycholinguistics, and Information Science. It aims to bring together academic and industrial participants working in those areas.

Guidelines for paper submission

STIL 2025 accepts submissions of long and short papers. Long papers should describe finished, original, unpublished work with significant results, and will be presented orally. Short papers may report work in progress, negative results, opinion papers, or applications/demos, and will be presented as posters.

Language

All papers submitted to STIL must be written in Portuguese, English or Spanish.

Length

Long papers may have up to ten (10) pages of content (including tables and figures), and unlimited pages of references. Short papers should have up to six (6) pages of content and unlimited pages of references. Authors will be asked whether they agree to have their long paper relocated as a poster if reviewers recommend it.

Format

Paper formatting must follow the SBC guidelines available at the SBC website and also in Overleaf .

Reviewing process

All papers submitted to STIL will be reviewed by 3 experts in the field. The reviewing process will be double-blind, and therefore, papers should not contain any information regarding their authorship in the header or body of the text. Self-references that reveal the author’s identities must be avoided. For example, instead of “As we previously showed (Silva, 2005) …” authors should use “Silva (2005) previously showed …”.

Submission policy

By submitting papers to STIL 2025, all authors agree that at least one of them will register for the conference and present the paper in case of acceptance. This registration must take place before the deadline for the camera-ready version of the paper and must be made in the category established by the organization.

Anonymity Period

The following rules and guidelines are intended to protect the integrity of the double-blind review and ensure that submissions are reviewed fairly. The rules refer to the period of anonymity, which goes from 1 month before the submission deadline until the date your work is accepted or rejected. Works withdrawn during this period will no longer be subject to these rules.

During the anonymity period, you may not make a non-anonymous version of your paper available online to the general community (eg, via a pre-print server). Versions include papers with essentially the same scientific content but possibly differ in minor details (including title and structure) and/or length.
You may submit an anonymous version to the conference if you published a non-anonymous version of your paper online before the anonymity period began. The submitted version must not refer to the non-anonymous version, and you must inform the program chairs that there is a non-anonymous version.
You may not update the non-anonymous version during the anonymity period and we ask that you do not advertise it on social media or take other actions that further compromise the double-blind review during the anonymity period.
You can make an anonymous version of your article available (for example, on OpenReview or ArXiv), even during the anonymity period.

Please note that while you are not prohibited from making a non-anonymous version available online prior to the start of the anonymity period, this makes the double-blind review more difficult to maintain and therefore we encourage you to wait until the end of the anonymity period.

Important dates

(all deadlines are 11:59 p.m. UTC-12:00 – anywhere on Earth!)

Deadline for long and short paper submission: June 01, 2025
Notification to authors: August 01, 2025
Camera-ready versions due: August 15, 2025

Submission system

Long and short papers should be submitted as PDF files via the JEMS system (https://jems3.sbc.org.br/events/346) by the deadline indicated above.
