| # Licensed image search corpus |
|
|
| A public, reproducible image-search dataset built from Wikimedia Commons. Each |
| WebDataset sample contains a 384px WebP derivative and JSON source metadata. |
| Images are selected using their source copyright-license metadata: CC0/public |
| domain, CC BY, and CC BY-SA; NC and ND are excluded. There is no single blanket |
| license for the images. Consult each sample's license, license_url, creator, |
| and source_url before reuse. Source metadata does not establish other rights. |
|
|
| Fields include image_id, title, creator, license, source_url, full_url, width, |
| height, description, tags, and source SHA-1. The retrieval model is |
| ViT-B-16-SigLIP pretrained on webli, producing normalized 768-dimensional vectors. |
| Archives preserve alpha where available; embedding composites transparency onto |
| white. The originals remain at their source URLs. |
| |
| Build code: https://github.com/Zahide4/imgsearch/blob/main/cloud_corpus.py |
| The pipeline uses sequential API requests per worker, bounded filename ranges, |
| API-generated thumbnails, retry backoff, and saved restart cursors. |
|
|
| The corpus is a prototype, has uneven subject coverage, and has not been |
| comprehensively reviewed for content quality or suitability for any specific use. |
