| # Tibetan OCR — Stok |
|
|
| <!-- DRAFT. Open-access subset of the OPTranskribus alignment set. Numbers measured 2026-08-18. --> |
|
|
| **806 page images of Tibetan Kangyur manuscripts (uchen) with page-level Unicode |
| transcriptions.** The transcriptions were produced by **[OpenPecha](https://openpecha.org/)** |
| with the [Transkribus](https://www.transkribus.org/) handwritten-text-recognition |
| platform over **BDRC** manuscript scans of the **Stog Palace Kangyur** (`MW22083`) |
|
|
| Used in the **BDRC Tibetan OCR** effort; see the model |
| [`BDRC/tibetan-ocr`](https://huggingface.co/BDRC/tibetan-ocr) and the |
| [evaluation benchmark](https://huggingface.co/datasets/BDRC/tibetan-ocr-benchmark). |
