Embodiment

[0037] Such as figure 1 As shown, an embodiment of the present invention is based on a multi-agent simulation method for information dissemination and public opinion evolution, and simulates information dissemination and public opinion evolution.

[0038] 1) The construction process of BA scale-free network is as follows:

[0039] A) initial generation m 0 random network of nodes.

[0040] B) Add a node every time, and connect with known m nodes, m0 , the probability of connection is proportional to the degree of the node.

[0041] C) Repeat the above steps until the stop condition is met.

[0042] A network of 200 nodes built according to this method is as follows figure 2 shown.

[0043] 2) Construction of information dissemination model

[0044] In the process of information dissemination, we use informed to indicate whether each node in the network is informed, and spread to indicate the node's propagation status. At the initial moment when the message enters the n...

Abstract

The invention discloses a simulation method for information dissemination and public opinion evolution based on multi-agents, which comprises the following steps: selecting a scale-free network as a simulation medium; constructing a negative index model of the individual netizen's willingness to spread; defining the attributes of netizen and the netizen Interaction rules between groups, based on the interaction rules to build a continuous opinion evolution model of netizens; information dissemination is combined with the evolution process of netizens’ public opinion opinions to simulate information dissemination and opinion evolution, and the model stops at a preset time step. By introducing information dissemination, netizen interaction rules and various attribute definitions, the present invention can better reflect the law of public opinion and information dissemination together in the real society, reflect the differences among netizens, and discover the relationship between information dissemination and public opinion evolution law.

Description

technical field [0001] The invention relates to a simulation method, in particular to a multi-agent-based information dissemination and public opinion evolution simulation method. Background technique [0002] With the continuous development of social networks, the threat of public opinion information disseminated through social networks is also increasing. Public opinion dissemination refers to the behavior of disseminating public opinion information through social networks. It has the characteristics of fast dissemination, wide dissemination range, and difficulty in restraint. Its dissemination is difficult to effectively control through artificial means. At the same time, due to the limitations of network management and the virtuality of network users, it provides a breeding ground for the spread of public opinion on social networks, and the spread of negative public opinion has become one of the major hidden dangers affecting social stability and the development of peopl...
