What is finbert-tone?
FinBERT-tone is a specialized BERT model designed for financial sentiment analysis. It's built upon the FinBERT architecture, which was pre-trained on an extensive corpus of financial texts totaling 4.9B tokens. This particular model has been fine-tuned specifically for tone analysis using 10,000 manually annotated sentences from analyst reports, making it highly accurate for detecting positive, negative, and neutral sentiments in financial contexts.
Implementation Details
The model is implemented using the Transformers library and can be easily integrated into existing NLP pipelines. It's based on the BERT architecture and has been trained on three main types of financial documents: Corporate Reports (2.5B tokens), Earnings Call Transcripts (1.3B tokens), and Analyst Reports (1.1B tokens).
