中文摘要：

基于复杂网络理论,引入和研究百度百科贡献者的合作网络的网络特性和生长机制。根据网页抓取的百度百科数据建立贡献者的百度百科合作网络,并对网络的相应拓扑指标进行分析,揭示网络的特点。用网络分形的思想对百度百科合作网络的网络谱的结构进行分析,结果发现百度百科合作网络的网络谱具有单分形的结构特性并且Hurst指数小于0.5。从分形的角度探讨网络的生长机制,百度百科合作网络的生长方式具有倾向于hub节点与非hub节点相连的特性。

英文摘要：

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.
