Special Issue "Information Diffusion in Social Networks"
Deadline for manuscript submissions: 28 March 2019
Studying social networks is the basis for understanding many complex phenomena in our societies.
When do social networks help the efficiency of economic and social activities, and when do they, instead, slow down the coordination and accruement of welfare? Do social networks provide a general informal answer to problems of integration and coexistence of different cultures, or do they increase polarization and segregation? The theory of complex networks has shown that the networks of human relations have statistical characteristics (as the so called ‘small world’ property) that accelerate the spread of opinions, but what if the behavior itself of people may either reduce this spread or instead incentivize the propagation of fake news? When is it the case that having wrong beliefs about reality does not only harm a single subject and his social neighbors, but may have cascade effects over a non-negligible portion of the overall society? In this respect, is the case of online social networks different from the case of real world acquaintances?
These are some of the questions at the core of this Special Issue.

Abstract: The sudden outbreak of the public crisis is often accompanied by the false information. The large-scale spread of false information will not only cause panic in the crowd, but it may also trigger a public crisis and cause secondary harm to the society,which puts forward higher demands on the government’s governance. Based on the theory of explosive percolation and combined with SI model, this paper proposes an improved false information dissemination model. Through the analysis of such indicators as the the largest cluster, explosive threshold, cluster merging and diffusion rate, explored the explosive mechanism of the emergence of false information. It is found that there is a threshold for the outbreak of the false information, and the outbreak size is almost zero when the threshold is smaller than the threshold. After the threshold is exceeded, the outbreak will occur rapidly in a short time. False information is most infective in the early stage, and gradually weakened with the increase of simulation steps. Based on this mechanism, this paper presents three kinds of false information governance options: random immunization, target-surrounded immunization, and comprehensive science. The rationality of different situations is verified through simulation experiments. Under the circumstance of frequent occurrence of false information and triggering of public crisis, It is of great significance to study the mechanism of its outbreak on the government intervention.
Title: Network Models of Information Diffusion Processes
Affiliation:University of Duisburg-Essen
Abstract:Network analysis is one of the main means for analysing information diffusion processes.
However, as the notion of an "information diffusion process" very much depends on the
application context, network models mapping those processes may differ very much.
Nodes can represent different entitites, for example, individuals, content items, or events. Apart
from the instantiation of nodes, an analyst also has to decide when and how to establish an edge
Furthermore, the strenght of network models to map structural characteristics often comes at a cost
of loosing temporal information about the underlying process since connections between nodes
are aggregated over time. In certain cases, however, information diffusion processes can be
captured in specific network models that bear an inherent notion of time.
This paper reviews and compares approaches of transforming data about information diffusion into
network structures with a special consideration of handling temporal information.
It will be shown by how modelling decisions affect the analysis of information diffusion using
network analysis techniques.
