科研合作网络及特性分析

为揭示超网络的某些特性,基于小世界模型和无标度模型,提出和建立两种超网络演化模型,并定义交叉度用于表征超网络节点之间合作关系,最后将超网络演化模型应用于中国原子能科学研究院核技术应用研究所科研合作网的实证分析。研究结果表明:不论是对于超网络理论模型还是实证分析,交叉度都能够优于以往的网络特性用于分析超网络不同层次之间节点的相互合作关系,为从理论上进一步深入分析超网络及其应用打下一定的基础。

The characteristic analysis of scientific collaboration supernetwork

In order to reveal some characteristics of supernetwork,in this paper based on the small -world and scale -free model,we put forward and established two kinds of supernetwork evolving models,and defined cross -degree which was used to quantify the cooperation relationship of supernetwork nodes.Finally we used the supernetwork evolving model to an-alyze scientific collaboration network of our department.The result showed that according to the supernetwork evolving mod-el and the empirical analysis,the cross -degree is better that other network characteristics and can be used to analyze the cooperation relationship of supernetwork nodes in different levels.These results lay a foundation for further analysis of su-pernetwork and its application from the theoretical model.
