The idea of Sentdex is to quantify the qualitative.

Sentdex is a sentiment analysis algorithm, termed by the meshing of "sentiment" and "index."

It understands the emotions people use in their online communication and translates them to computer language. This data can be used to gain a deeper understanding of the world, by showing you how people across the world feel about various topics, such as companies, politics, war and much more.
