(SentenceBERT for Financial News Sentiment Regression)

This repository contains the code for generating three models for Finance News Sentiment Analysis.

The models implemented are:

• A SentenceBERT with simple classifier.
• A BERT with simple classifier.
• A simple Bi-directional Long-Short Term Memory (LSTM) network.
• FinBERT from HuggingFace.
• SentenceBERT from HuggingFace

• FinEAS: https://huggingface.co/LHF/FinEAS (not available)
• FinBERT: https://huggingface.co/LHF/finbert-regressor (not available)

We used three partitions of the datasets from the February 11th, 2021. 6 months previous to that date, 1 year previous to that date and 2 years previous to the date mentioned.

We also evaluated the models 2 weeks later that date; that is to say, we evaluated from February 12th, 2021 to February 26th, 2021.

The table below shows the results:
