'Arianna Novaro'] Many important collective decision-making problems can be seen as multiagent versions of discrete optimisation problems. Participatory budgeting, for instance, is the collective version of the knapsack problem; other examples include collective scheduling, and collective spanning trees. Rather than…

Judgment aggregation studies how to combine individual judgments on logically related propositions into a collective judgment. Classical impossibility results show that sufficiently strong logical interconnections force dictatorship under natural aggregation axioms. In this paper, we ask whether such impossibility can…

Ranking Prediction Authors: ['Yixuan Even Xu' 'Hanrui Zhang' 'Yu Cheng' 'Vincent Conitzer'] Quantitative Relative Judgment Aggregation (QRJA) is a new research topic in (computational) social choice. In the QRJA model, agents provide judgments on the relative quality of different candidates, and the goal is to…

Aggregation with Simple Formulas Authors: ['Robert Bredereck' 'Junjie Luo'] Judgment aggregation is a framework to aggregate individual opinions on multiple, logically connected issues into a collective outcome. These opinions are cast by judges, which can be for example referees, experts, advisors or jurors, depending…

judgments Authors: ['Patrick Stinson' 'Jasper van den Bosch' 'Trenton A. Jerde' 'Nikolaus Kriegeskorte'] Every day, we judge the probability of propositions. When we communicate graded confidence (e.g. "I am 90% sure"), we enable others to gauge how much weight to attach to our judgment. Ideally, people should share…

'Elana Souza Carrapateira' 'Bruna Cristine Scarduelli Pacheco' 'Márcio Teixeira Oliveira' 'Guilherme Botega Torsoni' 'Jiyan Yari'] The Analytic Hierarchy Process (AHP) is a multi-criteria decision support method and is widely applied in many areas. The original AHP method proposed by Thomas L. Saaty in the 1970s…

This paper evaluates the performance of different voting and probability aggregation methods using a dataset of 451,200 probability judgments from 376 participants on 1200 general knowledge claims. We investigate the Condorcet Jury Hypothesis, according to which majority voting tends to yield outcomes more accurate…

Valuable information for decision-making can be obtained by collecting and analyzing opinions from diverse stakeholder or respondent groups, which usually have different backgrounds and are variously affected by the topics under survey. For this to succeed, it is necessary to manage the uncertainty of respondents’…

Collective decision making is often a customary action taken in government crowdsourcing. Through ensemble of opinions (popularly known as judgment analysis), governments can satisfy majority of the people who provided opinions. This has various real-world applications like urban planning or participatory budgeting…

'Mark Malinowski'] Title: Abstract An intelligence information system (IIS) is a particular kind of information systems (IS) devoted to the analysis of intelligence relevant to national security. Professional and military intelligence analysts play a key role in this, but their judgments can be inconsistent, mainly due…

'Rajagopalan Srinivasan'] We compare the traditional risk and opportunity assessment method, which relies on fixed values for impacts (or potentials) and probabilities, with a graphical approach that incorporates the representation of uncertainties. To date, this graphical risk assessment method, in combination with…

The aim of a recommender system is to suggest to the user certain products or services that most likely will interest them. Within the context of personalized recommender systems, a number of algorithms have been suggested to generate a ranking of items tailored to individual user preferences. However, these algorithms…

Protein aggregation is a common and complex phenomenon in biological processes, yet a robust analysis of this aggregation process remains elusive. The commonly used methods such as center-of-mass to center-of-mass (COM–COM) distance, the radius of gyration (R_g_), hydrogen bonding (HB) and solvent accessible surface…

Condensates in living cells can exhibit a complex rheology including viscoelastic and glassy behaviour. This rheological behavior of condensates was suggested to regulate polymerisation of cytoskeletal filaments and aggregation of amyloid fibrils. Here, we theoretically investigate how the rheological properties of…
