One approach to natural language processing that has gained tremendous traction recently is the vecotrization of words to represent their representation in a complex context. Deep Learning based sentiment analysis and general classifiers help improve the accuracy compared to results achieved with “classical” text analysis approaches. Tools like Word2Vec or GloVe are based on trained vectorized learning models that help in building commodity NLP available to a broad range of audience.
