Recommender API -- README The goal of the project is to provide easy-to-understand, easy-to-use, fully-documented APIs for developers to write cool Drupal modules based on recommender algorithms. The module provides several core algorithms in the API framework. But in order to use those algorithms in Drupal, you need to write your own modules using the APIs, or use existing modules such as the User-to-user Recommendation module. Module developers: Please refer to README.html, or visit the project homepage at: http://drupal.org/project/recommender
