## Openrice Review Classification dataset

From [github.com/Christainx/Dataset_Cantonese_Openrice](https://github.com/Christainx/Dataset_Cantonese_Openrice).

The dataset includes 60k instances from Cantonese reviews in Openrice.

The rating ranks from 1-star (very negative) to 5-star (very positive). The instances are shuffled in order to disperse reviews of same restaurant.

### Code for the splits creation

```
import datasets

def load_openrice():
    # https://github.com/Christainx/Dataset_Cantonese_Openrice/blob/master/Openrice_Cantonese.7z
    with open('Openrice_Cantonese.txt') as file:
        for i, line in enumerate(file):
            label = int(line[0])
            text = line[1:].strip()
            yield {'text': text, 'label': label}


ds = datasets.Dataset.from_generator(load_openrice)
print(ds)
dsd = ds.train_test_split(0.1, seed=42)
dsd['test'].to_json('data/test.jsonl', orient='records', force_ascii=False)
dsd['train'].to_json('data/train.jsonl', orient='records', force_ascii=False)
print(dsd)
```
