Twitter-roBERTa-base for Emotion Recognition

This is a RoBERTa-base model trained on ~58M tweets and finetuned for emotion recognition with the TweetEval benchmark.

• Paper: TweetEval benchmark (Findings of EMNLP 2020).
• Git Repo: Tweeteval official repository.

<b>New!</b> We just released a new emotion recognition model trained with more emotion types and with a newer RoBERTa-based model. See twitter-roberta-base-emotion-multilabel-latest and TweetNLP for more details.
