社会经济网络动力学的唯象模型

Phenomenological Models of Socio-Economic Network Dynamics

George C. M. A. Ehrhardt, Matteo Marsili, Fernando Vega-Redondo

摘要:

我们研究了社会网络演化和动态的一般模型。该模型由网络上的动态和网络的演化组成。链接优先在“相似”节点之间形成,其中相似性由网络上发生的特定过程定义。两个过程之间的相互作用产生相变和滞后,如使用三个特定过程的数值模拟所示。我们得到的分析结果,使用平均场近似,并为一个特定的情况下,我们推导出一个精确的解决方案的网络。与现实世界的社交网络一样,我们发现高连接和低连接阶段以及历史依赖性共存。

英文摘要:

We study a general set of models of social network evolution and dynamics. The models consist of both a dynamics on the network and evolution of the network. Links are formed preferentially between 'similar' nodes, where the similarity is defined by the particular process taking place on the network. The interplay between the two processes produces phase transitions and hysteresis, as seen using numerical simulations for three specific processes. We obtain analytic results using mean field approximations, and for a particular case we derive an exact solution for the network. In common with real-world social networks, we find coexistence of high and low connectivity phases and history dependence.
