KcBERT is Korean Comments BERT pretrained on this Corpus set.  
(You can use it via Huggingface's Transformers library!)

This Kaggle Dataset contains **CLEANED** dataset preprocessed with the code below.

```python
import re
import emoji
from soynlp.normalizer import repeat_normalize

emojis = ''.join(emoji.UNICODE_EMOJI.keys())
pattern = re.compile(f'[^ .,?!/@$%~％·∼()\x00-\x7Fㄱ-힣{emojis}]+')
url_pattern = re.compile(
    r'https?:\/\/(www\.)?[-a-zA-Z0-9@:%._\+~#=]{1,256}\.[a-zA-Z0-9()]{1,6}\b([-a-zA-Z0-9()@:%_\+.~#?&//=]*)')

def clean(x):
    x = pattern.sub(' ', x)
    x = url_pattern.sub('', x)
    x = x.strip()
    x = repeat_normalize(x, num_repeats=2)
    return x
