Small-world patterns in Chinese phrase networks

Recently, the structure and function of complex networks have become one of the hottest topics in statistical physics and interdisciplinary sciences. Studies have shown that real networks containing a huge mount of nodes do not form and evolve in a random way as expected, but they display peculiar features. The most surprising one is the small-world effect, which is commonly shared by food webs, the web of human sexual contacts, word networks, etc. Moreover, the scale-free property of degree distributions also emerges on Internet and protein networks.
