ANALYSIS OF RUMOR PROPAGATION DYNAMICS IN COMPLEX NETWORKS

Advances in Complex Systems
Considering that rumors propagation is affected by many factors in real life, based on the SIRS infectious disease model in complex networks, an extended ISRI rumor propagation model is proposed by using the probability function to define the influence mechanisms such as trust mechanism, and suspicion mechanism.

Rumor propagation in the framework of evolutionary game analysis

Chaos: An Interdisciplinary Journal of Nonlinear Science
With the ubiquity of social networks, rumors spread easily, leading to increasing attention on their dissemination. In this context, the spread of rumors is influenced not only by the content of the information itself but also by the behavior of various actors over social networks.

Detecting Emerging Rumors by Embedding Propagation Graphs

2020
In this paper, we propose a propagation-driven approach to discover newly emerging rumors which are spreading on social media. Firstly, posts and their responsive ones (i.e., comments, sharing) are modeled as graphs. These graphs will be embedded using their structure and node’s attributes.

A study on propagation and refutation of rumors

2012
This dissertation looks into rumor propagation mechanisms, and the mechanisms by which rumor refutations are processed. Prior research that associate the factors with rumor propagation are: the importance of the rumor content, rumor target's identification with the rumor object, belief congruence, degree of belief in the rumor, rumor valence and ...

Research on Model of Network Rumor Propagation

2018 5th International Conference on Information Science and Control Engineering (ICISCE), 2018
In the era of vigorous development network media, rumors propagation procedure becomes more complex, faster, and more dangerous. The identification and control of Internet rumors is important to related net-check departments. This paper establish an index system to evaluate the level of internet rumors and rumor credibility index system according to ...

Role of affect in marketplace rumor propagation

Marketing Intelligence & Planning, 2019
PurposeRumors about products and brands are common occurrence in the marketplace. Often these rumors are shared among consumers using the word of mouth channel. The spread of these rumors is fast and can lead to significant consequences to products and brands.

Dynamic Analysis of a Reaction–Diffusion Rumor Propagation Model

International Journal of Bifurcation and Chaos, 2016
The rapid development of the Internet, especially the emergence of the social networks, leads rumor propagation into a new media era. Rumor propagation in social networks has brought new challenges to network security and social stability. This paper, based on partial differential equations (PDEs), proposes a new SIS rumor propagation model by ...

Influence of network structure on rumor propagation

Physics Letters A, 2007
Abstract Rumor propagation in complex networks is studied analytically and numerically by using the SIR model. Analytically, a mean-field theory is worked out by considering the influence of network topological structure and the unequal footings of neighbors of an infected node in propagating the rumor.

Modeling the Bifurcation Dynamics of Rumor Propagation in the Spatial Environment

International Journal of Bifurcation and Chaos
The harm caused by rumors is immeasurable. Studying the dynamic characteristics of rumors can help control their spread. In this paper, we propose a nonsmooth rumor model with a nonlinear propagation rate. First, we utilize the positive invariant regions to prove the boundedness of solutions.
