Remember from above that the AFINN lexicon measures sentiment with a
numeric score between -5 and 5, while the other two lexicons categorize
words in a binary fashion, either positive or negative. To find a
sentiment score in chunks of text throughout the novel, we will need to
use a different pattern for the AFINN lexicon than for the other two.
