Embodiment Construction

[0040] The method of the present invention will be described in detail below with reference to the drawings and embodiments.

[0041] Such as figure 2 Shown is a network structure diagram of 10 nodes in the embodiment of the present invention.

[0042] A method for constructing a rumor propagation model that integrates personal behavior and social interaction, comprising the following steps:

[0043] 1. Input the social network graph G(V,E,C), the user node in the social network is V={v 1 ,v 2 ,...,v 10}, a weighted directed edge set describing the relationship between users and contains each user's curiosity about rumors A i (t i ), individual education level β i , Personal memory forgetting factor ω i individual characteristics of C i ={A i ,β i ,ω i}. Network structure such as figure 1 As shown, the relevant data are shown in Table 1 and Table 2. The rumor was started by user v 1 start to propagate, that is, v 1 is the propagation source node, record v 1...

Abstract

The invention provides a rumor propagation model construction method integrating personal behavior and social interaction, belonging to the technical field of social network modeling and analysis. Firstly, a set of related user nodes is created to record the rumor propagation process, and the set is initialized; a collection of associated user nodes is created and initialized and used to record rumor propagation; depending on how the rumor continues to spread, the group of communicators of users who are still spreading the rumor on social networks is updated on a time-by-time basis until the rumor ceases to exist on social networks. The method of the invention introduces the oscillator simple harmonic motion model to carry out overall modeling on the education level of the individual user,the individual memory forgetting factor, and the probability of the individual receiving and spreading rumors, which not only integrates the important influencing factors in the existing model, but also highlights the role of the rumor duration time.

Description

technical field [0001] The invention relates to a method for constructing a social network rumor propagation model, in particular to a method for constructing a rumor propagation model that integrates personal and social interactions in a social network, and belongs to the technical field of social network modeling and analysis. Background technique [0002] With the gradual deepening of the Internet age, numerous online social networks have emerged, such as Twitter, Facebook, and Weibo. Almost everyone uses social networks to make friends or spread information every day. Due to the rapid development of online social networks, a large number of rumors spread in social networks, causing great harm. [0003] Since the spread of rumors in social networks is very similar to the spread of viruses, the existing rumor spread models are mainly based on the infectious disease model series, which consider the influence of human factors on rumor spread. Among them, human factors such ...
