Algorithms for range-skyline queries
Proceedings of the 20th International Conference on Advances in Geographic Information Systems, 2012Let S be a set of n points in Rd where each point has t ≥ 1 real-valued attributes called features. A range-skyline query on S takes as input a query box q e Rd and returns the skyline of the points of q ∩ S, computed w.r.t. their features (not their coordinates in Rd).

Skyline Diagram: Finding the Voronoi Counterpart for Skyline Queries
2018 IEEE 34th International Conference on Data Engineering (ICDE), 2018Skyline queries are important in many application domains. In this paper, we propose a novel structure Skyline Diagram, which given a set of points, partitions the plane into a set of regions, referred to as skyline polyominos. All query points in the same skyline polyomino have the same skyline query results.

Exception-Tolerant Skyline Queries
2014This paper presents an approach aimed at reducing the impact of exceptional points/outliers when computing skyline queries. The phenomenon that one wants to avoid is that noisy or suspect elements “hide” some more interesting answers just because they dominate them in the sense of Pareto.

Fuzzy Dominance Skyline Queries
2007Skyline is an important and recent proposal for expressing user preferences. While no one best row exists, Skyline discards rows which are worse on all criteria than some other and retrieves non-dominated or the best ones that match user preferences. Nevertheless, some dominated rows could be interesting to user requirement, but they will be rejected ...

U-Skyline: A New Skyline Query for Uncertain Databases
IEEE Transactions on Knowledge and Data Engineering, 2013The skyline query, aiming at identifying a set of skyline tuples that are not dominated by any other tuple, is particularly useful for multicriteria data analysis and decision making. For uncertain databases, a probabilistic skyline query, called P-Skyline, has been developed to return skyline tuples by specifying a probability threshold.

Skyline queries help users make intelligent decisions over complex data, when different and often conflicting criteria are considered. Such queries return a set of data points that are not dominated by any other point on all dimensions. Skyline queries have been studied in centralized systems and more recently in distributed environments, such as web ...
