Build and host a Sentiment Analysis Model based on Naive Bayes on Azure

The dataset used for training the model consists of public tweets which are already labelled -- positive or negative. There are lots of npm package that implement the Naive Bayes algorithm out there and most of them are very similar in the way they implement Bayes theorem. Some packages are a bundle of NLP algorithms. The package used in the demo is this. After initializing the bayes classifier in your node application, it is very easy to train the model and use it for real world applications.
