DBLP科研合作网络的建模与拓扑特征分析

使用DBLP(databasesystemsandlogicprogramming)提供的文献索引作为原始数据，对计算机及其相关领域合作发表论文形成的科研合作网络进行了研究.通过解析xml元数据，构建DBLP科研合作网络拓扑并计算其网络拓扑常规参数，分析了若干参数的统计特征，发现DBLP科研合作网络是小世界网络，但无标度特性不明显；该科研合作网络的中心与边缘拓扑反映不同的科研合作模式；DBLP复杂网络的k核与科学家的h-指数并无强相关性.最后使用观察结果讨论了复杂网络的研究发展及本实验室在计算机相关领域的学术定位情况.

Modeling and Topological Features Analysis of DBLP Coauthor Network

Using the DBLP computer science bibliography as raw data， the coauthor network of the computer and related fields was studied. By parsing the extracted xml metadata， the coauthor network topology was constructed， and the general parameters of the network topology were calculated. In addition， the statistical characteristics of a number of parameters were analyzed， which could be found that the DBLP coauthor network is a typical small world network yet with no obvious scale free property. Different research cooperation modes were reflected by the topologies of center and bordering of the network， and there is no strong correlation of the k core of the network with the scientist’s h index. The development of complex network and the positioning of our lab in the computer related field at the academic level were finally discussed.
