本文对合作网络描述的几个实际系统进行了实证研究,并提出了一个模型来理解所得结果。我们研究了四个非社会系统,分别是北京和扬州的公交线路网络、中国的旅游线路网络、中国烹饪的淮扬食谱,以及一个社会系统,即好莱坞演员的合作网络。为了解释与程度分布、行为-程度分布和行为-大小分布相关的结果(特别是关于程度分布,可能更适合使用拉伸指数分布(SED)),我们提出了一个简单的模型来显示这种网络出现的可能的进化机制。模型的解析和数值计算结果与实证结果吻合较好。
In this paper we present an empirical study of a few practical systems described by cooperation networks, and propose a model to understand the results obtained. We study four non-social systems, which are the Bus Route Networks of Beijing and Yangzhou, the Travel Route Network of China, Huai-Yang recipes of Chinese cooked food, and a social system, which is the Collaboration Network of Hollywood Actors. In order to explain the results related to the degree distribution, act-degree distribution and act-size distribution (especially about the degree distribution, which may be better fitted using a stretched exponential distribution (SED)), we suggest a simple model to show a possible evolutionary mechanism for the emergence of such networks. The analytic and numerical results obtained from the model are in good agreement with the empirical results.
