协作网络中的社会惰性

Social inertia in collaboration networks

Jose J. Ramasco, Steven A. Morris

摘要:

本文研究了协作网络的性质,采用加权图的形式表示它们的单模投影。边的权重直接是伙伴关系重复的次数。这种表现使我们能够定义“社会惯性”的概念,衡量作者继续与以前的合作伙伴合作的趋势。我们使用一组经验数据集来分析社会惯性的几个方面:1)它的概率分布,2)它与其他属性的相关性,以及3)网络中邻居之间惯性的相关性。我们还将这些实证结果与最近提出的合作网络增长理论模型的预测进行了对比。

英文摘要:

This work is a study of the properties of collaboration networks employing the formalism of weighted graphs to represent their one-mode projection. The weight of the edges is directly the number of times that a partnership has been repeated. This representation allows us to define the concept of "social inertia" that measures the tendency of authors to keep on collaborating with previous partners. We use a collection of empirical datasets to analyze several aspects of the social inertia: 1) its probability distribution, 2) its correlation with other properties, and 3) the correlations of the inertia between neighbors in the network. We also contrast these empirical results with the predictions of a recently proposed theoretical model for the growth of collaboration networks.
