# BERT-base-multilingual-cased finetuned for Part-of-Speech tagging

This is a multilingual BERT model fine tuned for part-of-speech tagging for English. It is trained using the Penn TreeBank (Marcus et al., 1993) and achieves an F1-score of 96.69.

## Usage
A *transformers* pipeline can be used to run the model:

```python
from transformers import AutoTokenizer, AutoModelForTokenClassification, TokenClassificationPipeline

model_name = "QCRI/bert-base-multilingual-cased-pos-english"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForTokenClassification.from_pretrained(model_name)

pipeline = TokenClassificationPipeline(model=model, tokenizer=tokenizer)
outputs = pipeline("A test example")
print(outputs)
```


## Citation
