# CORD: A Consolidated Receipt Dataset for Post-OCR Parsing

CORD dataset is cloned from [clovaai](https://github.com/clovaai/cord) GitHub repo

- Box coordinates are normalized against image width/height
- Labels with very few occurrences are replaced with O:

```
replacing_labels = ['menu.etc', 'menu.itemsubtotal', 
                    'menu.sub_etc', 'menu.sub_unitprice', 
                    'menu.vatyn', 'void_menu.nm', 
                    'void_menu.price', 'sub_total.othersvc_price']
```
