Skyline Diagram: Efficient Space Partitioning for Skyline Queries [PDF]
IEEE Transactions on Knowledge and Data Engineering, 2021 Skyline 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.

Skyline Queries with Noisy Comparisons [PDF]
Proceedings of the 34th ACM SIGMOD-SIGACT-SIGAI Symposium on Principles of Database Systems, 2015 We study in this paper the computation of skyline queries-a popular tool for multicriteria data analysis-in the presence of noisy input. Motivated by crowdsourcing applications, we present the first algorithms for skyline evaluation in a computation model where the input data items can only be compared through noisy comparisons.

CoRR, 2022 Skyline and ranking queries are two of the most used tools to manage large data sets. The former is based on non-dominance, while the latter on a scoring function. Despite their effectiveness, they have some drawbacks like the result size or the need for a utility function that must be taken into account.
