# roberta-base-english-upos

## Model Description

This is a RoBERTa model pre-trained with [UD_English-EWT](https://github.com/UniversalDependencies/UD_English-EWT) for POS-tagging and dependency-parsing, derived from [roberta-base](https://huggingface.co/roberta-base). Every word is tagged by [UPOS](https://universaldependencies.org/u/pos/) (Universal Part-Of-Speech).

## How to Use

```py
from transformers import AutoTokenizer,AutoModelForTokenClassification
tokenizer=AutoTokenizer.from_pretrained("KoichiYasuoka/roberta-base-english-upos")
model=AutoModelForTokenClassification.from_pretrained("KoichiYasuoka/roberta-base-english-upos")
```

or

```py
import esupar
nlp=esupar.load("KoichiYasuoka/roberta-base-english-upos")
```
