高阶网络中的超链接社区

Hyperlink communities in higher-order networks

AI总结:

本文将链接社区扩展为超图中的超链接社区,通过超边层次聚类揭示高阶网络的层次与多尺度结构,并支持节点重叠归属及结构角色分类。

摘要:

许多网络都可以通过社区的存在来刻画,社区是由紧密相连的单元组成的群体。识别这些社区对于理解系统的整体功能可能至关重要。近年来,超图已成为对相互作用不限于成对、而可能涉及任意数量节点的系统进行建模的基础工具。在本研究中,我们采用一种对偶的社区检测方法,并将链接社区的概念扩展到超图。这一扩展使我们能够提取高度相关的超边所构成的信息丰富的簇。我们分析了在多种真实世界数据上对超边之间的距离矩阵应用层次聚类所得的树状图,结果表明超链接社区自然地凸显了高阶网络的层次化和多尺度结构。此外,超链接社区使我们能够提取节点的重叠成员身份,克服传统硬聚类方法的局限。最后,我们引入高阶网络制图法,作为一种实用工具,根据节点的相互作用模式和社区参与情况,将节点划分为不同的结构角色。该方法有助于在多种真实社会系统中识别不同类型的个体。我们的工作有助于更好地理解真实世界高阶系统的结构组织。

英文摘要:

Many networks can be characterised by the presence of communities, which are groups of units that are closely linked. Identifying these communities can be crucial for understanding the system's overall function. Recently, hypergraphs have emerged as a fundamental tool for modelling systems where interactions are not limited to pairs but may involve an arbitrary number of nodes. In this study, we adopt a dual approach to community detection and extend the concept of link communities to hypergraphs. This extension allows us to extract informative clusters of highly related hyperedges. We analyze the dendrograms obtained by applying hierarchical clustering to distance matrices among hyperedges across a variety of real-world data, showing that hyperlink communities naturally highlight the hierarchical and multiscale structure of higher-order networks. Moreover, hyperlink communities enable us to extract overlapping memberships from nodes, overcoming limitations of traditional hard clustering methods. Finally, we introduce higher-order network cartography as a practical tool for categorizing nodes into different structural roles based on their interaction patterns and community participation. This approach aids in identifying different types of individuals in a variety of real-world social systems. Our work contributes to a better understanding of the structural organization of real-world higher-order systems.
