Dataset Viewer
The dataset could not be loaded because the splits use different data file formats, which is not supported. Read more about the splits configuration. Click for more details.
Couldn't infer the same data file format for all splits. Got {NamedSplit('train'): ('csv', {}), NamedSplit('validation'): (None, {}), NamedSplit('test'): (None, {})}
Error code:   FileFormatMismatchBetweenSplitsError

GloSL — CE-CSL (Chinese Continuous Sign Language) → Chinese

Part of GloSL, a set of continuous sign language translation corpora in one format.

  • Sign language: Chinese Sign Language (csl)
  • Spoken language: Chinese (Mandarin) (zh)
  • Domain: daily-life sentences, recorded (in-the-wild backgrounds)
  • Samples: 5,988 (10.51 h) — splits {'train': 4973, 'dev': 515, 'test': 500}
  • Split policy: CE-CSL official train/dev/test (arXiv:2409.11960)
  • License: none stated (TFNet repo and mirror carry no licence; all rights reserved by default) — public; source: https://huggingface.co/datasets/freshlittlelemon/CE-CSL
  • Access: Poses published by GloSL on 27 Oct 2026, pending the authors' answer to a permission request of 7 Oct 2026. The repository is made private if the corpus's authors ask.
  • Cite: CE-CSL, arXiv:2409.11960 (2024)

Files

annotations.csv, card.json, poses/<NNNN>/<id>.pose. card.json holds the full provenance.

annotations.csv columns (same in every GloSL dataset; empty when not applicable): id, split, text, gloss, gloss_type, signer, start, end, fps, n_frames, video_ref, pose_file, video_file.

Poses

mediapipe-holistic, 543 points (POSE_LANDMARKS 33, FACE_LANDMARKS 468, LEFT_HAND_LANDMARKS 21, RIGHT_HAND_LANDMARKS 21), 3D. Coordinates: pixels of the frame the pose refers to (header width x height, depth 0); z raw. Confidence: body = MediaPipe visibility (1.0 where the source shipped none); face/hands 1 when detected; missing point = (0,0,0) with confidence 0. Frame rate: native, per file (also in annotations.csv). Normalization (glosl-norm-v1) is applied at load time, not stored. Note: MediaPipe Holistic from single-signer studio clips (no YOLO crop); native fps; normalization applied at LOAD time (KB/05).
