crisis_emotion_roberta
This emotion classification model is a fine-tuned version of 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):
- Anger (0.83)
- Sadness (0.67)
- Joy (0.69)
- Sympathy (0.80)
- Sarcasm (0.44)
- Neutral (0.64)
