Judgment aggregation is a mathematical theory of collective decision-making. It concerns
the methods whereby individual opinions about logically interconnected issues of interest …

Nowadays, online social networks, such as “Facebook” and “WeChat,” facilitate the
expression, diffusion, and interactions of individuals' opinions regarding various issues. In …

We present a formal model of opinion diffusion and formation which combines notions from
social network analysis together with concepts and techniques from judgment aggregation …

Collective decision making is concerned with aggregating information reported by a number
of individuals into a collective decision appropriately capturing the individual views as a …

We introduce a new approach for designing rules for participatory budgeting (PB), the
problem of deciding on the use of public funds based directly on the views expressed by the …

Graph aggregation is the process of computing a single output graph that constitutes a good
compromise between several input graphs, each provided by a different source. One needs …

We provide a comprehensive analysis of the computational complexity of the outcome
determination problem for the most important aggregation rules proposed in the literature on …

Abstract Endriss et al.(2012) initiated the complexity-theoretic study of problems related to
judgment aggregation. We extend their results on the manipulation of two specific judgment …
