Embodiment Construction

[0060] The drawings are for illustrative purposes only, and should not be construed as limitations on this patent; in order to better illustrate this embodiment, some parts in the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product;

[0061] For those skilled in the art, it is understandable that some well-known structures and descriptions thereof may be omitted in the drawings. The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0062] Such as figure 1 As shown, when a susceptible node is in contact with a node capable of spreading (including an infected node and a part of latent nodes) with a probability of β, the susceptible node will be transformed into a latent node. The latent node will be transformed into an infected node with the probability of κ, and transformed into an immune node with the probability of δ. Infected nod...

Abstract

The present invention discloses a social network based message propagation model, which is a method, based on the special line of the crowd in the network and the average degree of the nodes in the social network, for carrying out modeling analysis on message propagation in the social network and proposing a node importance based rumor immune strategy. The dynamic equations of the <k> SLIR message propagation model are established in the small-world network; by virtue of the method disclosed by the present invention, influences of nodes in various states in the social network, on message propagation can be realistically taken into consideration; and according to the node importance based improved rumor immune strategy proposed by the present invention, propagation of rumors in social network can be better inhibited.

Description

technical field [0001] The present invention relates to the field of Internet social network modeling and analysis, in particular to a social network-based message dissemination model, which is to analyze the social network by modeling the message dissemination in the social network and data fitting, and propose a model-based rumor immunity model. Strategy. Background technique [0002] With the rapid development of social networks, more and more users use social networks such as Facebook, Twitter and Weibo to make friends and disseminate information. Since the structure of the social network is close to a scale-free network, there will be some nodes connected to a large number of other nodes, called "hub nodes". speed of propagation. Research on social networks has a SIR rumor propagation model based on the spread of infectious diseases, but these studies have not considered the implicit ability of some users to spread rumors. Contents of the invention [0003] The pre...
