collaborative filtering in rails [closed]
I'm looking for a solution for collaborative filtering in rails or even possible examples. So far I have only found acts_as_recommendable which looks useful but I noticed it hasn't had any updates in the last 2 years.
Does anyone know of any other solutions and/or examples?
Have you evaluated Apache Mahout? It is a Java based solution, with HTTP access to recommendation engine.
Reference:
Introducing Mahout
This pertains to the examples part of your question, as both the libraries mentioned below are in Java.
The article referenced in above answer, written by Apache Mahout-Taste library author, has neat examples, source code of the examples( using 2.5GB wikipedia data) , and an excellent packaging to run
and see those examples in action, in a few minutes.

Here is another open source recommendation engine. easyrec
In 2013, there's the ActiveRecord Reputation System gem by Twitter. There's also a free RailsCast on the topic.
here is a 50 line recommendation system in Ruby: http://www.igvita.com/2007/01/15/svd-recommendation-system-in-ruby/
