# FinTwitBERT

FinTwitBERT is a language model specifically pre-trained on a large dataset of financial tweets. This specialized BERT model aims to capture the unique jargon and communication style found in the financial Twitter sphere, making it an ideal tool for sentiment analysis, trend prediction, and other financial NLP tasks.

## Dataset
FinTwitBERT is pre-trained on Taborda et al.'s [Stock Market Tweets Data](https://ieee-dataport.org/open-access/stock-market-tweets-data) consisting of 943,672 tweets, including 1,300 labeled tweets. All labeled tweets are used for evaluation of the pre-trained model, using perplexity as a measurement. The other tweets are used for pre-training with 10% being used for model validation.

## Model details
We use the [FinBERT](https://huggingface.co/ProsusAI/finbert) model and tokenizer from ProsusAI as our base. We added two masks to the tokenizer: `@USER` for user mentions and `[URL]` for URLs in tweets. The model is then pre-trained for 10 epochs using loss at the metric for the best model. We apply early stopping to prevent overfitting the model.

The latest pre-trained model and tokenizer can be found here on huggingface: https://huggingface.co/StephanAkkerman/FinTwitBERT.
