摘要:

在加权复杂网络中,拓扑和权密切相关,这反映在它们的模块化结构中。我们提出了一个简单的网络模型,其中的权重是动态生成的,它们塑造了发展中的拓扑结构。通过调整模型参数的权重的重要性,产生的网络经历了一个渐进的结构过渡,从一个模块自由的拓扑结构与社区。该模型还再现了大型社交网络的许多特征,包括“弱链接”属性。

英文摘要:

Topology and weights are closely related in weighted complex networks and this is reflected in their modular structure. We present a simple network model where the weights are generated dynamically and they shape the developing topology. By tuning a model parameter governing the importance of weights, the resulting networks undergo a gradual structural transition from a module free topology to one with communities. The model also reproduces many features of large social networks, including the "weak links" property.
