# BERT BASE (cased) finetuned on Bulgarian part-of-speech data

Pretrained model on Bulgarian language using a masked language modeling (MLM) objective. It was introduced in
[this paper](https://arxiv.org/abs/1810.04805) and first released in
[this repository](https://github.com/google-research/bert). This model is cased: it does make a difference
between bulgarian and Bulgarian. The training data is Bulgarian text from [OSCAR](https://oscar-corpus.com/post/oscar-2019/), [Chitanka](https://chitanka.info/) and [Wikipedia](https://bg.wikipedia.org/).

It was finetuned on public part-of-speech Bulgarian data.

Then, it was compressed via [progressive module replacing](https://arxiv.org/abs/2002.02925).

### How to use

Here is how to use this model in PyTorch:

```python
>>> from transformers import pipeline
>>> 
>>> model = pipeline(
>>>     'token-classification',
>>>     model='rmihaylov/bert-base-pos-theseus-bg',
>>>     tokenizer='rmihaylov/bert-base-pos-theseus-bg',
>>>     device=0,
>>>     revision=None)
>>> output = model('Здравей, аз се казвам Иван.')
>>> print(output)
