TLDR
These findings show that coupling the detection and anti-rumor strategy by embedding agents in the network, the authors call them beacons, is an effective means of fighting the spread of rumor, even if these beacons do not share information.Abstract:
In this paper we study and evaluate rumor-like methods for combating the spread of rumors on a social network. We model rumor spread as a diffusion process on a network and suggest the use of an "anti-rumor" process similar to the rumor process. We study two natural models by which these anti-rumors may arise. The main metrics we study are the belief time, i.e., the duration for which a person believes the rumor to be true and point of decline, i.e., point after which anti-rumor process dominates the rumor process. We evaluate our methods by simulating rumor spread and anti-rumor spread on a data set derived from the social networking site Twitter and on a synthetic network generated according to the Watts and Strogatz model. We find that the lifetime of a rumor increases if the delay in detecting it increases, and the relationship is at least linear. Further our findings show that coupling the detection and anti-rumor strategy by embedding agents in the network, we call them beacons, is an effective means of fighting the spread of rumor, even if these beacons do not share information.read more

The spread of true and false news online
TL;DR: A large-scale analysis of tweets reveals that false rumors spread further and faster than the truth, and false news was more novel than true news, which suggests that people were more likely to share novel information.

Cost-Efficient Strategies for Restraining Rumor Spreading in Mobile Social Networks
TL;DR: A heterogeneous-network-based epidemic model that incorporates the two kinds of methods to describe rumor spreading in MSNs is proposed that can restrain rumors in a continuous or periodical manner and guarantee cost efficiency.

Collective dynamics of small-world networks
TL;DR: Simple models of networks that can be tuned through this middle ground: regular networks ‘rewired’ to introduce increasing amounts of disorder are explored, finding that these systems can be highly clustered, like regular lattices, yet have small characteristic path lengths, like random graphs.

Maximizing the spread of influence through a social network
TL;DR: An analysis framework based on submodular functions shows that a natural greedy strategy obtains a solution that is provably within 63% of optimal for several classes of models, and suggests a general approach for reasoning about the performance guarantees of algorithms for these types of influence problems in social networks.

Incomplete ordering of the voter model on small-world networks
TL;DR: It is shown that the voter model on small-world networks does not display the emergence of complete order in the thermodynamic limit, and the nontrivial connectivity pattern leads to the counterintuitive conclusion that long-range connections inhibit the ordering process.
