Teaser: simple word clustering
In the next chapter, we cover some miscellaneous (yet very important) text mining subjects including:
- TDM/DTM weighting
- Dealing with TDM/DTM sparsity
- Capturing metadata
- Simple word clustering for topics
- Analysis on more than one word
For now, let's simply create a new visual called a dendrogram from our coffee_tweets. The next chapter will explain it in detail.
