摘　　要：以Wiki网络百度百科为研究对象,采用实证研究方法,收集百度百科184 470条词条映射为复杂网络。通过计算该网络的节点度分布、平均距离、簇系数,得出以知识主题为节点的知识协作网络具有无标度和小世界特征。与现有复杂网络演化模型以及万维网、Internet、科研协作网的实证研究结果进行对比,初步揭示知识协作网络的演化规律。This paper adopts empirical research method,with Wiki network baidu-baike for research object,184 470 topics are collected and mapped into complex network.By calculating the node degree distribution,the average path length and the clustering coefficient of the network,it is got that the knowledge cooperation network with knowledge topic has the features of scale free and small world.In comparison of the existing evolving mode for complex network with the result demonstrated by empirical research on World Wide Web,Internet and Science collaboration graph,the evolving rule is initially revealed for the knowledge cooperation network.
