Ranking a Set of Objects using Heterogeneous Workers: QUITE an Easy Problem

no code implementations3 Oct 2023 Alessandro Nordio, Alberto Tarable, Emilio Leonardi

We focus on the problem of ranking $N$ objects starting from a set of noisy pairwise comparisons provided by a crowd of unequal workers, each worker being characterized by a specific degree of reliability, which reflects her ability to rank pairs of objects.

Ranking a set of objects: a graph based least-square approach

no code implementations26 Feb 2020 Evgenia Christoforou, Alessandro Nordio, Alberto Tarable, Emilio Leonardi

We propose a class of non-adaptive ranking algorithms that rely on a least-squares optimization criterion for the estimation of qualities.

no code implementations23 Dec 2015 Alessandro Nordio, Alberto Tarable, Emilio Leonardi, Marco Ajmone Marsan

We investigate crowdsourcing algorithms for finding the top-quality item within a large collection of objects with unknown intrinsic quality values.
