  • ABSTRACT: This document reports on a set of widely used evaluation measures for recommender systems. The measures described in this document are well known by recommender system scientific community. In particular, all the first four measures reported, Precision and Recall, and MAE and ROC, assume to know which are the \"good\" results and which are the \"bad\" ones. This is done without looking at the real content of the involved objects. These measures are useful (and are used) to evaluate recommender systems that try to mimic the user behavior by estimating or predicting his future choices. By using them, we can only give a binary evaluation of recommendations (good/not good), without knowing the real quality of both recommended and not recommended results. In order to overcome this limitation, a series of other approaches have been proposed. Some of them give a quality measure based on the content of the objects. They compare the content of recommended items against the desired content (literal)
