Sentiment analysis is a form of Natural Language Processing (NLP) that identifies and quantifies text data emotional states and subjective information of the topics, persons and entities within it. Traditionally performed using algorithms such as Naïve Bayes or Support Vector Machines. It's also historically been a supervised task, using labeled datasets to train algorithms, requiring large datasets that are carefully selected, categorized and labeled manually by humans. Today, the consensus is clear, Deep Learning methods achieve better accuracy on most NLP tasks than other methods. And right now the undisputed Kings of NLP are large pre-trained models called Transformers. Their architecture aim to solve sequence-to-sequence tasks while handling long-range input and output dependencies with attention and recurrence.
The devil is in the details, we need lots of data and label finance data is hard to come by, thus we are going to build a large dataset based on a small sample of Financial Articles, which we will subsequently be used to build a Sentiment Analysis model that can measure 'sentiment' of financial data.
