Embodiment Construction

[0037] Preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the principles of the present invention.

[0038] According to a specific embodiment of the present invention, a social network information propagation tracking method based on a latent propagation set is disclosed, such as figure 1 As shown, it specifically includes the following steps:

[0039] Step S1, adding potential propagation nodes PS class nodes into the traditional SIR model, and establishing an SIR model based on potential propagation sets;

[0040] Definition 1. The nodes on the social network are divided into three categories: the spreading node I with the ability to spread information, the healthy node S who has never heard of the news, and the immune node R who is not in...

Abstract

The invention relates to a social network information propagation tracking method based on latent propagation set. The social network information propagation tracking method comprises the following steps: setting up a SIR(selective information retrieval) model based on latent propagation set a latent propagation set; acquiring network information from social network, clustering and grouping, and setting up a classified database of hot spot messages; selecting the network hot spot from the classification database, sampling the social network and acquiring propagation parameters; acquiring new network hotspot messages, comparing the new network hotspot messages with the classified database of network hotspot messages, selecting the closest network hotspot message type and extracting the propagation parameters as the reference propagation parameters of the new network hot spot messages; adjusting the reference propagation parameters to further predict the propagation of the network hot spot messages and to do manual intervention. The social network information propagation tracking method is capable of being used in a different scale of artificial networks and real networks, the S, I, R three kinds of curve generated by the SIPR equations agree well with three kinds of simulation conditions and all shown a good result.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method for tracking social network information propagation based on latent propagation sets. Background technique [0002] In recent years, with the rapid development of the Internet, online social services (SNS) such as Weibo, Twitter and Facebook have penetrated into every aspect of people's daily life and become an important way for modern people to obtain and disseminate fresh information. Due to the ease and speed with which information is released and received on these platforms, many hot issues will spread rapidly at an "explosive" speed, reaching the level of "everyone knows" in a short period of time. In today's society, public opinion has become an invisible force that cannot be underestimated. They can influence the evolution of hot events to a certain extent, and have a certain impact on the response, refereeing and handling of events by relevant departments. Ther...
