摘要本文采用基于主体的建模方法，模拟了模因在社交媒体网络中的空间扩散过程。与其他研究不同的是，本文考察了空间和距离对模因传播的影响。模拟进行了仿真，并允许评估不同水平的效率，模因传播的空间和时间。分析的网络结构包括随机网络和偏好连接网络。模因扩散的模拟空间过程包括独立级联模型和线性阈值模型。在分析中使用了模拟和真实世界的社交网络。研究结果表明，信息源和意见领袖的数量影响模因的扩散过程。此外，地理仍然是重要的空间传播过程中的模因在社会媒体网络。
ABSTRACT This article reports the findings from simulating the spatial diffusion processes of memes over social media networks by using the approach of agent-based modeling. Different from other studies, this article examines how space and distance affect the diffusion of memes. Simulations were carried out to emulate and to allow assessment of the different levels of efficiency that memes spread spatially and temporally. Analyzed network structures include random networks and preferential attachment networks. Simulated spatial processes for meme diffusion include independent cascade models and linear threshold models. Both simulated and real-world social networks were used in the analysis. Findings indicate that the numbers of information sources and opinion leaders affect the processes of meme diffusion. In addition, geography is still important in the processes of spatial diffusion of memes over social media networks.
