基于密度的社交网络聚类

Density-based clustering of social networks

Giovanna Menardi, Domenico De Stefano

摘要:

基于密度的聚类的模态公式的基本思想是将组与数据的概率密度函数的模态周围的区域相关联。在这里利用集群和密集区域的样本空间之间的对应关系来讨论这种方法的扩展到社交网络的分析。这种扩展似乎特别有吸引力:从概念上讲,高密度集群的概念非常适合网络中的社区,被视为在其邻域中具有密集本地联系的个体的集合。网络中密度的概率概念的缺乏变成了所提出的方法的主要优势,其中量化演员的角色和位置的节点措施可用于获得不同的社区配置。该方法允许识别聚类的层次结构,其可以捕获聚类结构的不同程度的分辨率。这一特征很好地符合社交网络的性质,解开了社会聚合中个体的不同参与。

英文摘要:

The idea underlying the modal formulation of density-based clustering is to associate groups with the regions around the modes of the probability density function underlying the data. This correspondence between clusters and dense regions in the sample space is here exploited to discuss an extension of this approach to the analysis of social networks. Such extension seems particularly appealing: conceptually, the notion of high-density cluster fits well the one of community in a network, regarded to as a collection of individuals with dense local ties in its neighbourhood. The lack of a probabilistic notion of density in networks is turned into a major strength of the proposed method, where node-wise measures that quantify the role and position of actors may be used to derive different community configurations. The approach allows for the identification of a hierarchical structure of clusters, which may catch different degrees of resolution of the clustering structure. This feature well fits the nature of social networks, disentangling a different involvement of individuals in social aggregations.
