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 …

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 …

A wide variety of formal frameworks have been proposed in the literature to both perform
and analyse collective decision making. Here several agents report an individual view and …

Egalitarian considerations play a central role in many areas of social choice theory.
Applications of egalitarian principles range from ensuring everyone gets an equal share of a …

In many settings, a collective decision has to be made over a set of alternatives that has a
combinatorial structure: important examples are multi-winner elections, participatory …

Judgment aggregation (JA) studies how to aggregate truth valuations on logically related
issues. Computing the outcome of aggregation procedures is notoriously computationally …

Opinion diffusion models the spread of information among agents whose connections are
given by a social network. We study opinion diffusion via Boolean networks, in which agents …

Abstract Description logics (DLs) are knowledge representation languages that are used in
the field of artificial intelligence (AI). A common technique is to query DL knowledge bases …

Judgment Aggregation (JA) is the task of aggregating individual judgments over logical
formulas into a collective judgment set. The doctrinal paradox by Kornhauser and Sager [13] …
