基于情报学期刊科研论文信息,建立了一个作者科研合作网络模型。通过理论分析和仿真验证,网络模型节点的度分布(作者合作人数)符合幂率分布,该网络是一种无尺度网络模型。为了说明作者合作网络模型的有效性,对2001年1月至2006年12月期间发表在《情报学报》、《情报科学》、《现代图书情报技术》、《图书情报工作》期刊上的科研论文进行统计,分别建立了作者合作网络。根据实际数据计算出网络模型的参数设置,网络模型的计算机仿真和理论结果与实证统计数据结论一致。
Based on the scientific articles from the informatics journals, a author collaboration network model is presented By the theoretic analysis and computer simulation, the degree distribution of the network nodes is a power law and this network is a scale-free network. In order to make sure the validity of the network model, we gather the articles during the year 2001-2006 from four Journals of the Informatics, and construct the author collaboration networks. By setting the parameters of the network model, the demonstration results are consistent with that of the network simulation and the theoretic calculation of the model.
