More Sentiment Comparisons

Here, the window was 10% of the total sentence count, which was approximately 700 overall. I entered the following in Python:

my_file = "/Users/john/Code/texts/sentiment/mdg.txt"
smooth_plots(my_file, 70)

And here is the graph:

The entire script is available as a [gist]gh.
