## Introduction |
|
|
This is a validation set split off from the historical dataset included in [BUT-LCC](https://huggingface.co/datasets/BUT-FIT/BUT-LCC) corpus. |
|
|
Furthermore, to avoid direct contamination from BUT-LCC, this set is filtered against the historical dataset from BUT-LCC by our fuzzy deduplication pipeline. |

## Legal Information & Data Origin |
|
|
This dataset consists of OCR'd documents since 1850, publicly available from the [Czech Digital Library](https://www.digitalniknihovna.cz/). We use [PeroOCR](https://pero-ocr.fit.vutbr.cz/) for optical character recognition (OCR). CZLC members do not own the distributed documents. |
