Chapter 6. Social Media Insight Using Naive Bayes

Text-based datasets contain a lot of information, whether they are books, historical documents, social media, e-mail, or any of the other ways we communicate via writing. Extracting features from text-based datasets and using them for classification is a difficult problem. There are, however, some common patterns for text mining.

We look at disambiguating terms in social media using the Naive Bayes algorithm, which is a powerful and surprisingly simple algorithm. Naive Bayes takes a few shortcuts to properly compute the probabilities for classification, hence the term naive in the name. It can also be extended to other types of datasets quite easily and doesn't rely on numerical features. The model in this chapter is a baseline for text mining studies, as the process can work reasonably well for a variety of datasets.

We will cover the following topics in this chapter:

  • Downloading data from social network APIs
  • Transformers for...
