论文摘要
我们使用基于中性模型的生态方法来研究在线社交网络中关注的竞争。这种新颖的方法使我们能够分析一些生态模式，这些模式在信息生态系统的背景下也具有有见地的含义。具体而言，我们专注于研究与网络中模因的持久性以及系统能够维持共存模因的能力相关的模式的研究。我们不仅能够以近似的连续限制进行此类分析，而且还可以获得有限尺寸的离散系统的确切结果。
We used an ecological approach based on a neutral model to study the competition for attention in an online social network. This novel approach allow us to analyze some ecological patterns that has also an insightful meaning in the context of information ecosystem. Specifically, we focus on the study of patterns related with the persistence of a meme within the network and the capacity of the system to sustain coexisting memes. Not only are we able of doing such analysis in an approximated continuum limit, but also we get exact results of the finite-size discrete system.
