无标度网络的出现
Emergence of Scale-Free Syntax Networks
摘要：
人类语言的进化使非遗传信息得以有效传播，从而创造了一种新的进化变化形式。儿童的语言发展提供了探索这种复杂的交际系统的机会，并为理解从原始语言到语言的过渡提供了一个窗口。在这里，我们提出了第一个分析的出现语法的复杂网络。一个以前没有报道过的，急剧的转变发生在大约两年的年龄从（前语法）树状结构的无标度，小世界的语法网络。这种过渡的性质支持存在一种内在的成分，这种成分弥漫在完整句法的出现中。这一观察结果很难用任何简单的网络增长模型来解释，因此表明某种内在的，也许是天生的成分在起作用。我们探索这个问题，使用一个最小的模型，能够捕捉到几个统计特征。我们的研究结果为适应性特征提供了证据，但它也表明，句法的一些关键特征实际上可能对应于非适应性现象。
英文摘要：
The evolution of human language allowed the efficient propagation of nongenetic information, thus creating a new form of evolutionary change. Language development in children offers the opportunity of exploring the emergence of such complex communication system and provides a window to understanding the transition from protolanguage to language. Here we present the first analysis of the emergence of syntax in terms of complex networks. A previously unreported, sharp transition is shown to occur around two years of age from a (pre-syntactic) tree-like structure to a scale-free, small world syntax network. The nature of such transition supports the presence of an innate component pervading the emergence of full syntax. This observation is difficult to interpret in terms of any simple model of network growth, thus suggesting that some internal, perhaps innate component was at work. We explore this problem by using a minimal model that is able to capture several statistical traits. Our results provide evidence for adaptive traits, but it also indicates that some key features of syntax might actually correspond to non-adaptive phenomena.
