Microblog user relationship network evolution model construction method 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 present invention belongs to the interdisciplinary field of computer, communication and network technology, and is specifically a network evolution model construction for information network, especially a network topology feature that can be used to describe various real microblog user relationship networks method. Background technique [0002] With the rapid development of the Internet, rumors spread among the people with the help of social media. The rapid spread and wide range of influence not only directly endanger the healthy development of the Internet, but even bring actual or potential threats to the normal social order of the country. , For example, in 2014, there were "Rumors of the missing Malaysia Airlines plane", "Rumors of Kunming Terrorist Attack", "Rumors of Bombs on the Plane" and "Rumors of H7N9 Epidemic" in 2013. Governments all over the world, including my country, pay close attention to the harm caused by the spread of Interne...
