Abstract

The invention discloses a two-dimensional space-time PDE information propagation model with space factors and a solving method, and belongs to the technical field of online social networks. Accordingto the present invention, a two-dimensional space-time PDE information propagation kinetic model with the space factors is researched and constructed, and the solving method is provided. According tothe information propagation model, the social structure attributes and the geographical structure attributes of the social network users can be effectively combined, so that the purpose of analyzing the characteristics and rules of the information propagation in the space-time dimension in the online social network is better achieved, and a certain basis is provided for guiding the social public opinions, inhibiting rumor propagation, making propaganda strategies and making decisions in market competition.

Description

technical field [0001] The invention belongs to the technical field of online social networks, and in particular relates to a two-dimensional space-time PDE information propagation model with spatial factors and a solution method. Background technique [0002] Social networks (Online Social Network, OSN) such as Twitter and Sina Weibo have become important carriers and methods for people to maintain social relationships and disseminate information. Has a powerful influence. However, social networks are a double-edged sword for human society. While people spread and obtain information conveniently and quickly, they are also troubled by false rumors. Therefore, the study of the law and characteristics of information dissemination in social networks, and how to control information dissemination has important theoretical and practical significance for predicting and channeling public opinion, and is attracting the attention of the society. [0003] Existing information dissemi...
