# roberta-base-ainu-upos

## Model Description

This is a RoBERTa model pre-trained on Ainu texts (in カタカナ, Roman, and Кириллица) for POS-tagging and dependency-parsing, derived from [roberta-base-ainu](https://huggingface.co/KoichiYasuoka/roberta-base-ainu). 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-ainu-upos")
model=AutoModelForTokenClassification.from_pretrained("KoichiYasuoka/roberta-base-ainu-upos")
```

or

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