Reasoning about opinion dynamics in social networks

Journal of Logic and Computation, 2015
AbstractThis article introduces a logic to reason about a well-known model of opinion dynamics in social networks initially developed by Morris DeGroot as well as Keith Lehrer and Carl Wagner. The proposed logic is an extension of Łukasiewicz' fuzzy logic with additional equational expressivity, modal operators, machinery from hybrid logic and dynamic ...

Binary Opinion Models of Influence and Opinion Dynamics in Social Networks

The process of influence and opinion dynamics is predominant in many kinds of real-life situations involving agents’ interactions. This phenomenon is extensively analyzed in different fields and with the help of various methods and tools. Network analysis is particularly suitable for the study of influence and opinion formation.

Steering opinion dynamics through control of social networks

Chaos: An Interdisciplinary Journal of Nonlinear Science
In this paper, we propose a novel control approach for opinion dynamics on evolving networks. The controls modify the strength of connections in the network, rather than influencing opinions directly, with the overall goal of steering the population toward a target opinion.

Opinion Dynamics on Correlated Subjects in Social Networks [PDF]

IEEE Transactions on Network Science and Engineering, 2020
Understanding the evolution of collective beliefs is of critical importance to get insights on the political trends as well as on social tastes and opinions. In particular, it is pivotal to develop analytical models that can predict the beliefs dynamics and capture the interdependence of opinions on different subjects.

Mitigation of adversarial attacks on voter model dynamics by network heterogeneity

Journal of Physics: Complexity, 2023
Voter model dynamics in complex networks are vulnerable to adversarial attacks. In particular, the voting outcome can be inverted by adding extremely small perturbations that are strategically generated in social networks, even when one opinion is ...

Evolution of social power for opinion dynamics networks [PDF]

2017 55th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2017
This article studies the evolution of opinions and interpersonal influence structures in a group of agents as they discuss a sequence of issues, each of which follows an opinion dynamics model. In this work, we propose a general opinion dynamics model and an evolution of interpersonal influence structures based on the model of reflected appraisals ...

Bounded-confidence model of opinion dynamics with heterogeneous node-activity levels

Physical Review Research, 2023
Agent-based models of opinion dynamics allow one to examine the spread of opinions between entities and to study phenomena such as consensus, polarization, and fragmentation.

Dynamics of Public Opinions in an Online and Offline Social Network [PDF]

IEEE Transactions on Big Data, 2021
With the development of the information and Internet technology, the public opinions with big data will rapidly emerge in an online-offline social network, and an inefficient management of public opinions often will lead to the security crisis for either firms or governments.
