在本文中，我们探讨了复杂的网络性质的词搭配网络（Ferret，2002）从四个不同的体裁。每一个特定体裁的文档都被转换成一个以词搭配为边的词网络。我们以图形和统计的方式分析了这些网络的全局属性在不同流派之间以及同一流派中不同网络类型之间的变化。我们的研究结果表明，网络属性的分布在视觉上是相似的，但在统计上不同的流派，和有趣的变化出现时，我们考虑不同的网络类型在一个单一的流派。我们进一步研究了当我们将越来越多的搭配边添加到一个特定类型的图中时，全局属性如何变化，并观察到除了顶点的数量和最大连通分量的大小之外，网络属性通过跳跃和下降而分阶段变化。
In this paper, we explore complex network properties of word collocation networks (Ferret, 2002) from four different genres. Each document of a particular genre was converted into a network of words with word collocations as edges. We analyzed graphically and statistically how the global properties of these networks varied across different genres, and among different network types within the same genre. Our results indicate that the distributions of network properties are visually similar but statistically apart across different genres, and interesting variations emerge when we consider different network types within a single genre. We further investigate how the global properties change as we add more and more collocation edges to the graph of one particular genre, and observe that except for the number of vertices and the size of the largest connected component, network properties change in phases, via jumps and drops.
