A network analysis of the Chinese stock market

Huang, Wei-Qiang; Zhuang, Xin-Tian; Yao, Shuang - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 14, pp. 2956-2964

In many practical important cases, a massive dataset can be represented as a very large network with certain attributes associated with its vertices and edges. Stock markets generate huge amounts of data, which can be use for constructing the network reflecting the market’s behavior. In this...

How community structure influences epidemic spread in social networks

Wu, Xiaoyan; Liu, Zonghua - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 2, pp. 623-630

Two key features of social networks are the community structure and the high clustering coefficient. For understanding … their influences on dynamical processes, we present a model with both an adjustable clustering coefficient and an adjustable … degree of community. This model has an invariant degree distribution when its clustering coefficient is being adjusted. We …

The complexity of Chinese syntactic dependency networks

Liu, Haitao - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 12, pp. 3048-3058

This paper proposes how to build a syntactic network based on syntactic theory and presents some statistical properties of Chinese syntactic dependency networks based on two Chinese treebanks with different genres. The results show that the two syntactic networks are small-world networks, and...

Traffic dynamics based on a traffic awareness routing strategy on scale-free networks

Wang, Dan; Jing, Yuanwei; Zhang, Siying - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 12, pp. 3001-3007

By incorporating local traffic information into the shortest path routing strategy, we numerically investigate the effectiveness of the traffic awareness routing strategy for scale-free networks with different clustering. In order to characterize the efficiency of the packet-delivery process, we...

Clustering coefficients of growing networks

Shi, Dinghua; Zhu, Stuart X.; Liu, Liming - In: Physica A: Statistical Mechanics and its Applications 381 (2007) C, pp. 515-524

In this paper, we develop a general analytical method to compute clustering coefficients of growing networks. This method can be applied to any network as long as we can construct and solve the dynamic equation for the degree of any node. We also verify the accuracy of the method through simulation.
