# crisis_emotion_roberta

This emotion classification model is a fine-tuned version of [finiteautomata/bertweet-base-sentiment-analysis](https://huggingface.co/finiteautomata/bertweet-base-sentiment-analysis) on a dataset of 9,300 tweets in the Flint Water Crisis (Wu, Wong, Zhao, & Liu, 2021). It achieves the following results on the testing set:
0.75 accuracy, 0.74 weighted accuracy, and 0.68 macro accuracy. 

## Classify the primary emotion of a crisis tweet into one of the following 6 categories (The F-1 score for each emotion):
0. Anger (0.83)
1. Sadness (0.67)
2. Joy (0.69)
3. Sympathy (0.80)
4. Sarcasm (0.44)
5. Neutral (0.64)

## Intended uses & limitations

For classifying the emotion of English tweets during crises & disasters

## Training and evaluation data

Dataset: 9,300 tweets in the Flint water crisis. 
Each tweet was labeled by trained & qualified crowdsourcing workers for 3-5 times.
