We present a corpus professionally annotated for grammatical error correction (GEC) and fluency edits in the Ukrainian language.We have built two versions of the corpus -GEC+Fluency and GEC-only -to differentiate the corpus application.We collected texts with errors (33,735 sentences) from a diverse pool of contributors, including both native and non-native speakers.The data cover a wide variety of writing domains, from text chats and essays to formal writing.Professional proofreaders corrected and annotated the corpus for errors relating to fluency, grammar, punctuation, and spelling.This corpus can be used for developing and evaluating GEC systems in Ukrainian.More generally, it can be used for researching multilingual and low-resource NLP, morphologically rich languages, document-level GEC, and fluency correction.To test the effectiveness of our corpus, we trained a basic but reasonable baseline model.The corpus is publicly available at https://github.com/grammarly/ua-gec.
