JRuby Mahout Movies

This is a demo project for the Jruby Mahout gem. JRuby Mahout Movies is a website where users can vote for movies, receive recommendations based on their tastes and see similar movies.

This project is currently a work in progress. I am planning to release it and write an article in my blog by January 25, 2013.
