{"url":"/dataset/bukva","name":"Bukva","full_name":"Bukva: Russian Sign Language Alphabet","description_markdown":"We introduce a video dataset **Bukva** for Russian Dactyl Recognition task. Bukva dataset size is about **27 GB**, and it contains **3757** RGB videos with more than 101 samples for each RSL alphabet sign, including dynamic ones. The dataset is divided into training set and test set by subject `user_id`. The training set includes 3097 videos, and the test set includes 660 videos. The total video recording time is ~4 hours. About 17% of the videos are recorded in HD format, and 70% of the videos are in FullHD resolution.","description_withheld":null,"homepage":"https://github.com/ai-forever/bukva","introduced_date":"2024-10-11","introduced_date_note":null,"introduced_by":{"paper":"/paper/bukva-russian-sign-language-alphabet","title":"Bukva: Russian Sign Language Alphabet","first_author":"Karina Kvanchiani","url":null},"license":{"name":"CC BY-SA 4.0","url":"https://github.com/ai-forever/bukva/tree/main/license"},"modalities":[{"name":"Videos","url":"/datasets/modality/videos"},{"name":"RGB Video","url":"/datasets/modality/rgb-video"}],"tasks":[{"name":"Sign Language Recognition","url":"/task/sign-language-recognition","datasets_with_task":"/datasets/task/sign-language-recognition"},{"name":"Video Classification","url":"/task/video-classification","datasets_with_task":"/datasets/task/video-classification"}],"languages":[{"name":"Russian","url":"/datasets/language/russian"}],"variants":["Bukva"],"data_loaders":[],"num_papers_in_archive":1,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[{"leaderboard":"/sota/sign-language-recognition-on-bukva","task":"Sign Language Recognition","dataset_variant":"Bukva","rows":1,"metrics":["Accuracy (Top-1)"],"first_row_in_archive_order":{"model":"MobileNetV2_TSM","paper":"/paper/bukva-russian-sign-language-alphabet","metrics":{"Accuracy (Top-1)":"83.6"},"code_links":[{"title":"ai-forever/bukva","url":"https://github.com/ai-forever/bukva"}]},"note":"rows are the archive's own order at snapshot; nothing here re-ranks them"}],"papers_with_a_benchmark_row":[{"paper":"/paper/bukva-russian-sign-language-alphabet","title":"Bukva: Russian Sign Language Alphabet","date":"2024-10-11","rows_on_this_dataset":1,"code_links":1,"syntology":null}],"syntology_totals":{"read_at":"2026-09-25T09:33:49+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
