In this paper, we propose new metrics to accurately measure the concentration reinforcement of recommender systems and the enhancement of the “long tail”. We also conduct a comparative analysis of various RS algorithms illustrating the usefulness of the proposed metrics. Keywords Dispersion; Diversity; Long Tail; Popularity Reinforcement
