# SMM4H-2024 Task 2 Japanese RE

## Overview

This is a relation extraction model created by fine-tuning [daisaku-s/medtxt_ner_roberta](https://huggingface.co/daisaku-s/medtxt_ner_roberta) on [SMM4H 2024 Task 2b](https://healthlanguageprocessing.org/smm4h-2024/) corpus.

Tag set:
* CAUSED
* TREATMENT_FOR

## Usage

```python
from transformers import AutoModelForSequenceClassification, AutoTokenizer
import torch

text = "サンプルテキスト"
model_name = "yseop/SMM4H2024_Task2b_ja"
id2label = ['O', 'CAUSED', 'TREATMENT_FOR']

with torch.inference_mode():
    model = AutoModelForSequenceClassification.from_pretrained(model_name).eval()
    tokenizer = AutoTokenizer.from_pretrained(model_name)
    encoded_input = tokenizer(text, return_tensors='pt', max_length=512)
    output = re_model(**encoded_input).logits
    class_id = output.argmax().item()
    print(id2label[class_id])
```
