Elicitation and aggregation of multimodal estimates improve wisdom of crowd effects on ordering tasks
SCIENTIFIC REPORTS, 14(1).
TL;DR:
It is found that using multiple modalities of estimates from one group yields better collective estimates compared to mixing numerical estimates from one group with the ordinal estimates from a different group.

Derivations of large classes of facet defining inequalities of the weak order polytope using ranking structures
JOURNAL OF COMBINATORIAL OPTIMIZATION, 46(3).
author keywords: Order polyhedra; Weak orders; Rankings
TL;DR:
This paper derives five new large classes of FDIs by utilizing the equivalent representations of a weak order as a ranking of n alternatives that allows ties; this connection simplifies the construction of valid inequalities, and it enables groupings of characteristic vectors into useful structures.

A New Binary Programming Formulation and Social Choice Property for Kemeny Rank Aggregation
Decision Analysis, 18(4), 296–320.
TL;DR:
This work introduces a binary programming formulation for the generalized Kemeny rank aggregation problem—whose ranking inputs may be complete and incomplete, with and without ties—and develops a new social choice property, the nonstrict extended Condorcet criterion, which can be regarded as a natural extension of the well-known Condorcets.

A Comparison of Axiomatic Distance-Based Collective Intelligence Methods for Wireless Sensor Network State Estimation in the Presence of Information Injection
IEEE World Forum on Internet of Things, WF-IoT 2020 - Symposium Proceedings.
TL;DR:
This work proposes and compares methods based on collective intelligence ideas, namely consensus ranking and rating models, which are founded on axiomatic distances and intuitive social choice properties to assess a transmitted signal's strength with varying quantity and quality of incompleteness in the network’s readings.

Contributors: Y. Zhang *, M. Bansal * & *
TL;DR:
Two-stage stochastic models are introduced to deal with uncertainty in generation and demand encountered during the recovery process, and one of them incorporates conditional value-at-risk to measure the risk level of unrecovered load shed.
