# BART-base-ocr
This model is released as part of the paper [Leveraging LLMs for Post-OCR Correction of Historical Newspapers](https://aclanthology.org/2024.lt4hala-1.14/) and designed to correct OCR text. [BART-base](https://huggingface.co/facebook/bart-base) is fine-tuned for post-OCR correction of historical English, using [BLN600](https://aclanthology.org/2024.lrec-main.219/), a parallel corpus of 19th century newspaper machine/human transcription.

## Usage
```python
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM, pipeline

model = AutoModelForSeq2SeqLM.from_pretrained('pykale/bart-base-ocr')
tokenizer = AutoTokenizer.from_pretrained('pykale/bart-base-ocr')
generator = pipeline('text2text-generation', model=model.to('cuda'), tokenizer=tokenizer, device='cuda', max_length=1024)

ocr = "The defendant wits'fined �5 and costs."
pred = generator(ocr)[0]['generated_text']
print(pred)
```
