tweet-topic-base-multilingual

This model is based on cardiffnlp/twitter-xlm-roberta-base language model trained rained on ~198M multilingual tweets and finetuned for multi-label topic classification in English, Spanish, Japanese, and Greek.

The models is trained using TweetTopic and X-Topic datasets (see main EMNLP 2024 reference paper).
