...Discounted cumulative gain (DCG): While the aforementioned measures are mainly designed for binary judgments, DCG [65, 66] can leverage the relevance judgment in terms of multiple ordered categories, and has an explicit position discount factor in its definition....

...Then we use the measure nDCG (Normalized Discounted Cumulative Gain, with the value between 0 and 1, the higher the better) [9] to evaluate the quality of a ranking algorithm by comparing its output ranking results with the labeled ones (Table 5)....

...Thus, ARHR decays more slowly than R score but faster than NDCG. Online evaluation of ranking In an online experiment designed to evaluate the ranking of the recommendation list, we can look at the interactions of users with the system....

...A measure closely related to R-score and NDCG is Average Reciprocal Hit Rank (ARHR) [14] which is an un-normalized measure that assigns a utility 1/k to a successful recommendation at position k....
