Research about fractal growth mechanism of Baidu Baike cooperation network
百度百科合作网络的分形生长机制研究*

Based on the theory of complex network, introduced and analyzed the characteristic and growth mechanism of cooperation network of Baidu Baike contributors. From the very beginning, built Baidu Baike cooperation network model on base of the caught data of Baidu Baike. Analyzed corresponding topology indexes to explore the characteristics of the network.Then used an idea of network fractal to analyze the structure of the spectra of this cooperation network, found fractal structure in the spectra and the Hurst exponent H<0.5.Explored the growth mechanism from the perspective of fractal. The growth of Baidu Baike cooperation network tends to have a characteristic that hub links to non-hub.
