Workshop on Automata, Formal and Natural Languages 2025 (WAFNL 2025)

WAFNL is an international workshop focused on Automata, Formal Languages, Natural Language Processing and Computational Linguistics. Its main aim is to encourage cooperation among formal language researches, NLP researchers, linguist in Middle Europe, and between their students.

The workshop will consist of a regular papers track, an overview and work-in-progress papers track and an open session. The workshop is part of the ITAT conference, which takes place in Hotel Telgárt, Nízké Tatry, Slovakia from September 26th to September 30th. The workshop itself is supposed to hold on September 28th and September 29th.

Regular Papers

Regular papers should present new scientific results.

• It must be written in English and present new results not published elsewhere.
• If you cross-submit your paper to multiple conferences/journals and it gets accepted and published elsewhere, you must withdraw it from WAFNL before submitting the camera-ready version at the latest.
• Each paper will be reviewed by 2 reviewers.
• Accepted papers will be published in the proceedings of ITAT (CEUR proceedings, indexed in Scopus).
• The final version of a paper should comprise 5-15 pages including references, in two columns (latex style).
• The papers must be submitted through EasyChair.

Overview and Work-In-Progress Papers

Overview papers summarize research of the author(s) from a higher level of perspective and work-in-progress papers with preliminary results. Even negative results papers are welcome here.

• They will be presented during a separate track.
• The aim is to present the authors' research to a more general audience than just formal languages/NLP specialists – specialists in other branches of Computer Science
• Overview papers need not to include novel content; however, they should properly cite previous publications describing the work presented in the overview paper.
• Work-in-progress papers present ongoing research.
• The format for overview papers is the same as for regular papers.
• Accepted papers will not be included in the CEUR proceedings but a separate volume.

Open Session

To further encourage cooperation and sharing of information among automata and NLP researchers, we offer an opportunity for anyone to present her/his work, without writing a paper:

• Presentation of any own work, including already published work, work in progress, or research ideas, and review/overview presentations:
  • Bachelor, master and dissertation theses can also be presented
  • We accept any presentation matching the topic of the workshop (automata theory, formal languages computational linguistics and natural language processing)
• The presentation will NOT be accompanied by an entry in the conference proceedings
  • The title and the abstract of the presentation will only be posted on the workshop website
• Each submission will be presented as a poster at WAFNL including a short (5 minutes) oral presentation; the presenting author needs to register for the workshop until 20th August 2025
• Please submit here through EasyChair.
