Word frequency list for "A Hadoop-powered book recommendation system"

Word frequency list for the "A Hadoop-powered book recommendation system" experiment on the "Run My Experiment on GENI" blog: https://witestlab.poly.edu/blog/a-hadoop-powered-book-recommendation-system/
We generated a word frequency list from the entire Project Gutenberg corpus (a one-time step that makes subsequent queries much faster). We downloaded all of the available Project Gutenberg books over a period of a couple of days, storing them on a GENI VM. Once we had the books (~36,000 books at 17GB), we created a word frequency list (~ 3.6GB), where every line contained a stemmed word, a particular book ID, the total number of words in that book, and the number of times the stemmed word appeared.
