| # Dataset Card for OCR-Betsug |
|
|
| A line-to-text dataset for Tibetan OCR of the Betsug script. |
|
|
| ## Dataset Details |
|
|
| ### Dataset Description |
| - **Curated by:** Buddhist Digital Resource Center |
| - **Language:** Tibetan |
| - **Total Samples:** 28,318 line images with text transcriptions |
|
|
| ### Dataset Structure |
| - **Features:** |
| - `id`: Image file identifier |
| - `image`: Image file of text |
| - `label`: Text transcription |
|
|
| - **Splits:** |
| - **Train:** 28,318 samples |
|
|
| ## Uses |
|
|
| ### Direct Use |
| - Training and evaluation of Tibetan OCR models |
| - Betsug (or other Ume) script OCR development |
| - Comparative analysis of historical scripts |
| - Large-scale OCR model pretraining |
|
|
| ### Out-of-Scope Use |
| - Not be suitable for printed Tibetan texts or Uchen script |
| - May not suitably represent contemporary digital Tibetan fonts |
|
|
| ## Dataset Creation |
|
|
| ### Curation Rationale and Process |
| This dataset was created from 2 manuscripts to support the development of robust OCR systems for Tibetan literature, including handwritten material. |
|
|
|
|
| ## Usage |
|
|
| ```python |
| from datasets import load_dataset |
| |
| # Load training split |
| dataset = load_dataset("openpecha/OCR-Betsug", split="train") |
| |
| # Example features |
| print(dataset[0]) |
| # {'id': 'I1KG812780077_1', |
| # 'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=2133x52 at 0x7B784AD93860>, |
| # 'label': 'ཀྱི་ཐིག་ལེ་ཏེ་། རྟེན་དང་བརྟེན་པར་བཅས་པ་ཉིད་། རང་ཉིད་གསལ་བར་བྱིན་བརླབས་ན་། ཇི་ལྟར་སྣང་སྲིད་ཆོས་ཐམས་ཅད་། ལྷན་ཅིག་སྐྱེས་པའི་ངོ་བོར་'} |
