<h2> Description </h2>
Twitter is a social media network on which users post and interact with messages known as "tweets". It allows an user to post, like, and retweet tweets.
Twitter is also known by the excessive negativity or criticism by a great part of its users. Considering that, this application intends to classify a tweet according to its positivity. The positivity is measured in five categories:
- Extremely negative
- Negative
- Neutral
- Positive
- Extremely positive
The application is based on a BERT model fine tuned on the [Coronavirus tweets NLP dataset](https://www.kaggle.com/datasets/datatattle/covid-19-nlp-text-classification).
