【摘要】 基于科研论文作者合作方式,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-2006年12月期间发表在《情报科学》期刊上的科研论文进行统计,建立了作者合作网络。对作者合作网络进行数据分析,结果与网络模型结论一致,因此该模型可以很好描述作者合作网络的演化过程。更多还原

【Abstract】 Based on the collaboration ways of the authors,a author collaboration network model is presented.It is validated by the theoretic analysis and computer simulation that 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 period 2001.1 to 2006.12 in Journal of Information Science,and construct a author collaboration network.By analyzing the data of the network,the demonstration results are consistent with that of the model.Therefore,this model can be applied to study the evolvement of the author collaboration network.更多还原
