Abstract: Skyline queries have been proposed to express user’s preferences. Since the size of Skyline set increases as the number of criteria augments, it is necessary to rank high dimensional Skyline queries. In this work, we propose a new metric to rank high dimensional Skylines which allows to identify the k most interesting objects from the Skyline set (Top-k Skyline). We have empirically studied the variability and performance of our metric. Our initial experimental results show that the metric is able to speed up the computation of the Top-k Skyline in up to two orders of magnitude w.r.t. the state-of-the-art metric: Skyline Frequency.
