The Program Committee of the 17th Symposium in Information and Human Language Technology (STIL) invites submissions of original research papers for the STIL conference to be held in Cuiabá, Mato Grosso, Brazil, from October 19th to 22nd, 2026.
STIL is the most important event in Brazil, gathering researchers interested in publishing significant and novel results pertaining to Natural Language Processing (NLP) in general (not restricted to the processing of the Portuguese language). Since 2023, STIL has been held annually, supported by the Brazilian Computer Society (SBC) and the Brazilian Special Interest Group on Natural Language Processing (CE-PLN).
Relevant topics for STIL 2026 include, but are not limited to:
General topics such as:
Tools and Resources for NLP
LLMs, Neural and Vector Representation Spaces applied to NLP
Multilingualism and Cross-Lingual Methods in NLP
Evaluation methodology and empirical methods for NLP research
Corpus Linguistics
Knowledge Representation and Ontologies
NLP resources applied to Digital Humanities research
Psycholinguistics, Cognitive Modeling, and Linguistic Theories applied to NLP
Speech Processing
Multimodality and NLP
Ethics and sociotechnical aspects of NLP systems
Interpretability and Analysis of Models for NLP
Low-resource and Low-compute Approaches for NLP
Environmental impacts of NLP research and green NLP
NLP applications such as:
Morphological analysis, Part-of-Speech tagging, Text preprocessing
Phonetics and Phonology applied to NLP
Syntactic Representations and Parsing
Semantic representations and Semantic processing
Discourse and Pragmatics
Dialog and Interactive Systems
Information Retrieval, Extraction, and Classification
Machine Translation
Natural Language Generation and Summarization
Question Answering
Sentiment Analysis, Opinion Mining, and Argument Mining
Terminology, Terminography, Lexicology, Lexicography, Phraseology, Lexical Semantics
Textual Inference
Automatic Speech Recognition, Text to Speech and Speaker Identification / Diarization
Guidelines for paper submission
STIL 2026 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 Long papers should describe finished, original, unpublished work with significant results, and will be presented orally.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, present negative results, offer opinion papers, or showcase 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.
Starting this year, submissions must include a Limitations section, an Ethics Statement, and a description of how Generative AI was used in preparing the paper. Authors are allowed one additional page beyond the 10/6-page limit exclusively for these sections. If the paper is accepted, this additional page may also be used to include the acknowledgments.
Format
Paper formatting must follow the SBC guidelines, available on the SBC website and in Overleaf.
Reviewing process
All papers submitted to STIL will be reviewed by at least two experts in the field. The reviewing process will be double-anonymous; therefore, papers should not include any information about 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 ...”.
Reviewing Policy
All eligible authors of a submitted paper must serve as a reviewer, provided they meet at least one of the following criteria:
Hold a PhD degree or equivalent;
Have at least three published papers in the field of NLP; or
Have previously published in STIL.
Only authors who satisfy one or more of these requirements will be eligible to review submissions.
Submission policy
By submitting papers to STIL 2026, all authors agree that at least one of them will register for the conference and present the paper, should it be accepted. This registration must be completed before the camera-ready version deadline and submitted in the category established 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 are designed to maintain the integrity of the double-anonymous review process and ensure that submissions are evaluated 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 a non-anonymous version exists.
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-anonymous 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 before the start of the anonymity period, doing so makes it more difficult to maintain the double-anonymous review. Therefore, we encourage you to wait until the end of the anonymity period.
