复杂网络与人类语言

Complex networks and human language

Jinyun KE

摘要:

本文介绍了如何利用网络理论的最新发展来研究人类语言。有两个探索方向。一是研究语言系统中存在的网络。不同的词汇网络可以根据词汇之间的不同关系来构建,无论是语义还是句法。最近的研究表明,这些词汇网络具有小世界和无标度的特征。另一个探索方向是研究语言使用者的网络(即语言社区中人们的社交网络)及其在语言进化中的作用。社交网络还表现出小世界和无标度的特征,这是随机或规则网络模型无法捕捉的。在过去,语言变化和语言出现的计算模型通常假设人口具有随机或规则结构,并且很少讨论网络结构如何影响动态。在文章的第二部分,一系列的语言创新扩散的模拟模型被用来说明选择的人口结构的现实条件的语言变化建模的重要性。四种类型的社交网络进行了比较,表现出两类扩散动力学。虽然关于哪种类型的网络更适合建模的问题仍然存在,我们给出了一些初步的建议,选择类型的社交网络建模。

英文摘要:

This paper introduces how human languages can be studied in light of recent development of network theories. There are two directions of exploration. One is to study networks existing in the language system. Various lexical networks can be built based on different relationships between words, being semantic or syntactic. Recent studies have shown that these lexical networks exhibit small-world and scale-free features. The other direction of exploration is to study networks of language users (i.e. social networks of people in the linguistic community), and their role in language evolution. Social networks also show small-world and scale-free features, which cannot be captured by random or regular network models. In the past, computational models of language change and language emergence often assume a population to have a random or regular structure, and there has been little discussion how network structures may affect the dynamics. In the second part of the paper, a series of simulation models of diffusion of linguistic innovation are used to illustrate the importance of choosing realistic conditions of population structure for modeling language change. Four types of social networks are compared, which exhibit two categories of diffusion dynamics. While the questions about which type of networks are more appropriate for modeling still remains, we give some preliminary suggestions for choosing the type of social networks for modeling.
