# BERT for Sentiment Analysis of Japanese Twitter

This model was finetuned from [BERT for Japanese Twitter](https://huggingface.co/LoneWolfgang/bert-for-japanese-twitter), which was adapted from Japanese BERT by Tohoku NLP by continuing MLM on a Twitter corpus.

It used [Japanese Twitter Sentiment 1k (JTS1k)](https://huggingface.co/datasets/LoneWolfgang/japanese-twitter-sentiment) for finetuning, omitting the mixed examples.

## Labels
0 -> Negative; 
1 -> Neutral; 
2 -> Positive

## Example Pipeline
```python
from transformers import pipeline
sentiment = pipeline("sentiment-analysis", model="LoneWolfgang/bert-for-japanese-twitter-sentiment")
sentiment ("こちらのカフェ、サービスが残念でした。二度と行かないかな…😞 #がっかり")
```
```
[{'label': 'negative', 'score': 0.8242}]
