Abstract: Ranking is a ubiquitous concern in the context of decision making and search. In this talk, I will present the main approaches adopted in data-intensive applications to rank items and select the best options. After a brief historical overview covering a few well-known voting systems, I will move to the classical top-k queries and skyline queries, and discuss their advantages and limitations. I will then explore recent proposals hybridizing and extending these two approaches to get the best of both worlds, while also considering orthogonal aspects relevant for ranking items, such as fairness and diversification.
