This covers most of the existing evaluation metrics for recommender systems. Actually it covers not only evaluation metrics related to recommendation correctness like precision, recall and F-measure but also those related to users’ discovery like novelty, serendipity and diversity. I recommend this article not only for recommender systems researcher but also for researchers on information retrieval, pattern recognition and machine learning.
