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.

Sentiment Analysis

The FinTwitBERT-sentiment model leverages FinTwitBERT for the sentiment analysis of financial tweets, offering nuanced insights into the prevailing market sentiments.

Dataset

FinTwitBERT is pre-trained on several financial tweets datasets, consisting of tweets mentioning stocks and cryptocurrencies:

• StephanAkkerman/crypto-stock-tweets: 8,024,269 tweets
• StephanAkkerman/stock-market-tweets-data: 923,673 tweets
• StephanAkkerman/financial-tweets: 263,119 tweets

Model Details

Based on the FinBERT model and tokenizer, FinTwitBERT includes additional masks (@USER and [URL]) to handle common elements in tweets. The model underwent 10 epochs of pre-training, with early stopping to prevent overfitting.

Usage

Using HuggingFace's transformers library the model and tokenizers can be converted into a pipeline for masked language modeling.

from transformers import pipeline

pipe = pipeline(
    "fill-mask",
    model="StephanAkkerman/FinTwitBERT",
)
print(pipe("Bitcoin is a [MASK] coin."))
