万维网的指数增长已经将其转变为一种知识生态，其中高度多样化的信息以极其复杂和任意的方式联系在一起。但即便如此，正如我们在这里所展示的，网络中隐藏着秩序。我们发现网页在网站之间的分布遵循一个普遍的幂律：许多网站只有几个页面，而很少有网站有几十万个页面。这种普遍分布可以用一个简单的随机动态增长模型来解释。
The exponential growth of the World-Wide Web has transformed it into an ecology of knowledge in which highly diverse information is linked in an extremely complex and arbitrary manner. But even so, as we show here, there is order hidden in the web. We find that web pages are distributed among sites according to a universal power law: many sites have only a few pages, whereas very few sites have hundreds of thousands of pages. This universal distribution can be explained by using a simple stochastic dynamical growth model.
