Cosine similarity example

The plot of Animal Farm is pretty simple. In the beginning the animals are unhappy with following their human leaders. In the middle they overthrow those leaders, and in the end they become unhappy with the animals that eventually became their new leaders.

If done correctly, cosine similarity can help identify documents (chapters) that are similar to each other. In this exercise, you will identify similar chapters in Animal Farm. Odds are, chapter 1 (the beginning) and chapter 10 (the end) will be similar.
