Recommendable

Recommendable is an engine to provide a recommender system for the Ruby on Rails web application framework. It uses Redis as backend to provide recommendations based on like/dislike statements by the users. Recommendable employs a user-based kNN model for collaborative filtering with a variant of the Jaccard similarity coefficient adapted to like/dislike statements as a similarity measure.
