Output-sensitive Evaluation of Prioritized Skyline Queries
Niccolò Meneghetti, Denis Mindolin, Paolo Ciaccia, Jan Chomicki · 2015
Skylines assume that all attributes are equally important, as each dimension can always be traded off for another. Prioritized skylines (p-skylines) take into account non-compensatory preferences, where some dimensions are deemed more important than others, and trade-offs are constrained by the relative importance of the attributes involved.
