A Construction Method of Microblog User Relationship Network Evolution Model Based on Network Science

Abstract

The invention discloses a microblog user relationship network evolution model construction method based on network science. The method comprises a network initialization stage and a network evolution generation stage, wherein the amount of initial nodes and the topological structure of an initial network are set in the network initialization stage, and the network evolution generation stage respectively adopts four mechanisms, i.e. stochastic growth, preferential attachment, stochastic attachment and reverse attachment. The invention fully considers a key evaluation mechanism in a microblog user relationship network formation process, can truly reflect the topological characteristics of the microblog user relationship network, has simple structure, is free from the restriction of network size, is suitable for analyzing various topological characteristics of a real microblog user relationship network and researching a transmission mechanism of various pieces of information in the microblog user relationship network, is favorable for optimizing the topological structure of a real network so as to improve the propagation efficiency of useful information, and is favorable for preventing and controlling network rumor propagation to lower harm brought by network rumors.

Description

technical field [0001] The invention belongs to the interdisciplinary field of computer, communication and network technology, etc., and specifically relates to a network evolution model structure for information networks, especially a network evolution model that can be used to describe the topological characteristics of various real microblog user relationship networks. method. Background technique [0002] With the rapid development of the Internet, rumors spread among the crowd with the help of social media. The speed of spread and the wide range of influence not only directly endanger the healthy development of the Internet, but also bring real or potential threats to the normal social order of the country. For example, in 2014, "rumors of missing Malaysia Airlines passenger plane", "rumours of terrorist attack in Kunming", "rumours of bombs on planes" and "rumours of H7N9 epidemic" in 2013. Governments all over the world, including my country, have paid close attentio...
