Skyline Queries with Noisy Comparisons [PDF]

open access: yesProceedings 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.

I/O-Efficient Planar Range Skyline and Attrition Priority Queues [PDF]

open access: yes, 2013
In the planar range skyline reporting problem, we store a set P of n 2D points in a structure such that, given a query rectangle Q = [a_1, a_2] x [b_1, b_2], the maxima (a.k.a. skyline) of P \cap Q can be reported efficiently.
