Oct 15, 2019 � For a given multi-dimensional data set, a group skyline query returns the optimal groups not dominated by any other group of equal size.
Mar 21, 2017 � ABSTRACT. The top-k skyline groups query (k-SGQ) returns k skyline groups that dominate the maximum number of points in a given data set.
Feb 20, 2022 � Top-k and skylines are two important techniques that can be used to extract the best objects from a set. Both the approaches have well-known�...
