Recommendable

Recommendable is a recommendation plug-in for the Ruby on Rails web application framework. It uses Redis as backend to provide recommendations based on like/dislike statements by the users. The recommendation model used by Recommendable is user-based kNN, with a variant of the Jaccard coefficient adapted to like/dislike statements as similarity measure.
