Characterizing Controversiality of Topics Utilizing Eccentricity of Opinions
Northeast Journal of Complex Systems, 2023 Access to abundant biased information in echo chambers and social bubbles often intensifies opinions to the extremes. The extremization of opinions results in several topics becoming controversial.

Dynamics of opinion expression [PDF]
Physical Review E, 2020 Modeling efforts in opinion dynamics have to a large extent ignored that opinion exchange between individuals can also have an effect on how willing they are to express their opinion publicly. Here, we introduce a model of public opinion expression.

Dynamical affinity in opinion dynamics modeling [PDF]
Physical Review E, 2007 We here propose a model to simulate the process of opinion formation, which accounts for the mutual affinity between interacting agents. Opinion and affinity evolve self-consistently, manifesting a highly non trivial interplay. A continuous transition is found between single and multiple opinion states.

Dynamics of Opinion Polarization
IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2023 An evident peculiarity in real-life debates is polarization, which produces the push of people s opinions to extreme positions. It is a fundamental task to understand if opinion dynamics models built to understand the opinion formation processes can reproduce them.

Opinion dynamics on tie-decay networks
Physical Review Research, 2021 In social networks, interaction patterns typically change over time. We study opinion dynamics on tie-decay networks in which tie strength increases instantaneously when there is an interaction and decays exponentially between interactions. Specifically,

Opinion dynamics in finance and business: a literature review and research opportunities
Financial Innovation, 2021 Opinion dynamics is an opinion evolution process of a group of agents, where the final opinion distribution tends to three stable states: consensus, polarization, and fragmentation. At present, the opinion dynamics models have been extensively studied in

Opinion Dynamics on Discourse Sheaves [PDF]
SIAM Journal on Applied Mathematics, 2021 We introduce a novel class of Laplacians and diffusion dynamics on discourse sheaves as a model for network dynamics, with application to opinion dynamics on social networks. These sheaves are algebraic data structures tethered to a network (or more general space) that can represent various modes of communication, including selective opinion modulation

Opinion dynamics: public and private
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2022 We study here the dynamics of opinion formation in a society where we take into account the internally held beliefs and externally expressed opinions of the individuals, which are not necessarily the same at all times. While these two components can influence one another, their difference, both in dynamics and in the steady state, poses interesting ...

Social Depolarization and Diversity of Opinions—Unified ABM Framework
Entropy, 2023 Most sociophysics opinion dynamics simulations assume that contacts between agents lead to greater similarity of opinions, and that there is a tendency for agents having similar opinions to group together. These mechanisms result, in many types of models,

Noisy continuous-opinion dynamics [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2009 We study the Deffuant et al. model for continuous--opinion dynamics under the influence of noise. In the original version of this model, individuals meet in random pairwise encounters after which they compromise or not depending of a confidence parameter.
