Dear All,

At the turn of 2026 and 2027, the next edition of PolEval, a shared task competition for computational tools for processing Polish, will take place. The aim of the shared task is to improve the quality of existing solutions, test new algorithms and methods, and support the development of computational linguistics.

We are now opening the Call for task proposals for PolEval 2026. Until September 7, 2026, we invite submissions from individuals, teams, and organisations interested in preparing and coordinating shared tasks as part of the competition.

A task proposal should include: task title – a short and unambiguous name; task description – outlining its goal, scope, and main assumptions; motivation and relevance – in particular, information on whether a similar task has already been organised as part of other competitions or benchmarks, e.g. for other languages; if the proposal concerns a new problem or a problem specific to Polish, please highlight its uniqueness and potential importance for the development of natural language processing; task preparation status – in particular, information on the availability and status of training and test data, any licensing restrictions, and the expected date by which the complete dataset will be ready; evaluation procedure – a description of how systems will be evaluated, including the proposed metrics, result submission procedure, etc.; proposed timeline for running the task as part of PolEval 2026 – in particular, the expected dates for data release and completion of the evaluation. Task organisers will be responsible for preparing the task description, data, and evaluation procedure; communicating with participants; coordinating the review process for submitted papers; and publishing a paper summarising the task in the PolEval proceedings in the ACL Anthology https://aclanthology.org/venues/poleval/.

Task proposals should be sent to: lukasz.kobylinski@ipipan.waw.pl mailto:lukasz.kobylinski@ipipan.waw.pl PolEval 2026 schedule Call for task proposals: August 11, 2026 Task submission deadline: September 7, 2026 Notification of task acceptance: September 14, 2026 First call for participation/papers & release of Train and Test A data: October 13, 2026 Second call for participation/papers: November 13, 2026 Release of Test B data: December 1, 2026 Announcement of final results (Test B): December 8, 2026 Paper submission deadline: December 15, 2026 Notification of paper acceptance: January 5, 2027 Camera-ready paper due: January 19, 2027 Presentation of the results and publication of the PolEval proceedings in the ACL Anthology: March 2027 The following tasks have been organised in previous editions of PolEval:

Part of Speech Tagging Sentiment Analysis Dependency Parsing Named Entity Recognition Language Models Recognition and normalization of temporal expressions Lemmatization of proper names and multi-word phrases Entity linking Machine translation Automatic speech recognition Automatic cyberbullying detection Post-editing and rescoring of automatic speech recognition results Morphosyntactic tagging of Middle, New and Modern Polish Word sense disambiguation Information extraction and entity typing from long documents with complex layouts Punctuation restoration from read text Evaluation of translation quality assessment metrics Post-correction of OCR results Question answering challenge Punctuation prediction from conversational language Abbreviation disambiguation Passage retrieval Reading Comprehension Emotion and sentiment recognition Polish Automatic Speech Recognition Challenge Spotting Machine-Generated Text from Language Models for Polish (ŚMIGIEL) Gender-inclusive LLMs for Polish Polish Speech Emotion Recognition Challenge Across these tasks, more than 140 systems have competed, developed by researchers from academia and by private companies. Organising a task is a great opportunity not only to test and compare existing solutions, but also to draw the attention of the research and engineering communities to important challenges in Polish language processing.

More information about the competition is available on: the PolEval website http://poleval.pl/; the PolEval Discord server https://discord.gg/dpn94tUSyT, used for ongoing discussions and information exchange; PolEval on LinkedIn https://www.linkedin.com/company/18152015. We would also greatly appreciate your help in spreading the word about PolEval 2026 among your colleagues, students, PhD students, and others interested in computational linguistics and NLP.

Thank you in advance for your support and involvement. We look forward to receiving interesting proposals for tasks for PolEval 2026!

Best regards, Łukasz Kobyliński Maciej Ogrodniczuk Alina Wróblewska Institute of Computer Science, Polish Academy of Sciences
