Tonality & Sentiment Analysis

Description

The language of incoming messages is detected automatically. Based on the result appropriate Natural Language Processing is applied to determine the tonality (sentiment) of each message. Besides other methods we apply Naïve Bayes classification and word vectors. The step of automatic text analysis is particularly adapted and optimized for the domain of financial markets. For example, the word “long” has a very unique (positive) meaning in the context of financial markets whereas it might mean something negative in a different context, e.g. if a user review in Amazon writes about a “long” focusing time of a digital camera.
