Text Measures
Previously, we explored a model that exploits the links between the entities to help
us find the key players in the data. Here, we will focus on the Tweet's text to better
understand what the users are talking about. We move away from the network model
we've used previously and discuss other methods for text analysis. We first explore
topic modeling, an approach that finds natural topics within the text. We then move
on to sentiment analysis, the practice of associating a document with a sentiment
score.
