Finding character name frequency in books using Mathematica?

Posted 3 years ago

Hello! How might I find out how often a character's name appears in a book compared to another character? For example, if I wanted to see how often the name "Daisy" appears in the Great Gatsby as compared to the name "Gatsby"? I have tried WordCount but that doesn't work so far. Thanks for any help!

Take a look at this post: *400th anniversary of Shakespeare's death* https://community.wolfram.com/groups/-/m/t/842698 I recommend searching this forum, documentation, Wolfram blogs and other sites. There is a lot of useful information already published.

Start with StringPosition and work from there. Take a look at the first half of https://blog.wolfram.com/2017/12/07/tracking-a-descent-to-savagery-with-the-wolfram-language-plotting-sentiment-analysis-in-lord-of-the-flies/ where I did this with Lord of the Flies.

Try `WordCounts` instead of `WordCount`. For instance, if `myGatsby` is the variable holding the text of the book as a string, then you could use WordCounts[DeleteStopwords[myGatsby]] which produces an association whose keys are the words and whose values are their frequencies. In the copy I downloaded from Project Gutenberg Gatsby appears 199 times and Daisy 150 times.
