Problems solved by technology

However, in the dissemination of topics on real social networks, many users participate in it and discuss the topic from different angles and perspectives. Therefore, at the same time point, hundreds or thousands of new messages may be generated. mutual influence
However, this phenomenon of multi-message propagation under the same topic has been largely ignored in previous studies

Embodiment

[0053] Numerical simulation and empirical results

[0054] In the simulation stage, this embodiment constructs a message network containing 20 nodes, and the social network is a BA network containing N=1000 nodes. Each time a node joins the network, the newly increased number of connected edges is m=6, and the average degree =5.989.

[0055] (1) In the initial stage, a message network with 20 nodes and a social network with 1,000 nodes were constructed. 20 nodes were randomly selected from the social network, and each node propagated a different message. In the network, these 20 messages Simultaneous transmission.

[0056] (2) During the dissemination period, the user reads the 20 messages in the network with probability λ, and for the read messages, the user adopts the probability

[0057] to propagate.

[0058] (3) During the update period of the message network, the forwarding situation of all users at this time is counted. When the same user forwards differen...

Abstract

The invention discloses a modeling method of a multi-information dissemination model of a social network. The method: on the basis of a single-message dissemination model, expands it into multiple messages, and introduces different associations between each message and user memory attenuation, The final evolutionary stable state of information dissemination is obtained. The present invention combines the mutual influence among multiple messages, and is closer to the actual situation of the joint transmission of multiple messages in the social network. The present invention models and demonstrates the phenomenon of multi-information dissemination in social networks based on the social-message network framework. The invention improves the accuracy of multi-information dissemination prediction in the network, and provides effective model support for different aspects such as topic prediction, public opinion control, disease control, network marketing, and publicity strategies for products or advertisements launched by multiple enterprises.

Description

technical field [0001] The invention belongs to the technical field of information dissemination models, and in particular relates to a modeling method of a social network multi-information dissemination model. Background technique [0002] With the rapid development of Internet technology and the emergence of online social networks, the speed of information dissemination is faster, the scope of influence is wider, and the amount of information is also larger. Researchers have extensively used complex networks to describe the real-world communication dynamics, and information dissemination in the network is also a complex dynamic process, which is interactively affected by many factors, such as the topology of the network, the influence of information publishers, and the influence of users. interest preferences, the characteristics of the information itself, and so on. Understanding the dissemination process in complex networks is a core issue in the field of network scienc...
