### Model description
- This model was trained on **ZH, JA, KO**'s Wikipedia (5 epochs).

### How to use
```python
from transformers import AutoTokenizer, AutoModelForMaskedLM
tokenizer = AutoTokenizer.from_pretrained("conan1024hao/cjkbert-small")
model = AutoModelForMaskedLM.from_pretrained("conan1024hao/cjkbert-small")
```
- Before you fine-tune downstream tasks, you don't need any text segmentation.
- (Though you may obtain better results if you applied morphological analysis to the data before fine-tuning)

### Morphological analysis tools
- ZH: For Chinese, we use [LTP](https://github.com/HIT-SCIR/ltp).
- JA: For Japanese, we use [Juman++](https://github.com/ku-nlp/jumanpp).
- KO: For Korean, we use [KoNLPy](https://github.com/konlpy/konlpy)(Kkma class).

### Tokenization
- We use character-based tokenization with **whole-word-masking** strategy.

### Model size

- num_hidden_layers: 4
- hidden_size: 512
