Korean Sign Language Keypoint Dataset
Dataset Summary
This dataset contains the project keypoint cache used for Korean Sign Language isolated-word model training/evaluation experiments.
The keypoints were extracted with MediaPipe Holistic from a subset of the AI-Hub sign-language video dataset.
Source/reference: https://aihub.or.kr/aihubdata/data/view.do?srchOptnCnd=OPTNCND001&currMenu=115&topMenu=100&searchKeyword=%EC%88%98%EC%96%B4&aihubDataSe=data&dataSetSn=103
Contents
keypoint_cache.zip: compressed archive of the localkeypoint_cache/folder- Extracted archive structure:
keypoint_cache/1.Training/keypoint_cache/2.Validation/
- Keypoint files: 269518
.npyfiles in the local source folder - Local uncompressed folder size before upload: 27.4 GB
- Uploaded archive size: 20.2 GB
source_metadata.txt: local source metadata copied from/home/moon/metadata.txt
The archive is used instead of uploading hundreds of thousands of individual
.npy files so that the dataset can be downloaded and reproduced more reliably.

Usage
Download and extract:
unzip keypoint_cache.zip
The extracted folder should contain keypoint_cache/1.Training and
keypoint_cache/2.Validation.
Source And Licensing Notes
The raw videos originated from AI-Hub sign-language data. This repository contains derived keypoint cache files, not the original raw AI-Hub videos. Users should review and follow AI-Hub access/license terms for any downstream use.
AI Tools Used
AI tool used: Codex. Codex was used to package/upload the dataset and draft this dataset card. Codex was not used to create the source AI-Hub videos, keypoint labels, or original data split.
