摘要:

识别网络化系统中最具影响力的节点对于优化其功能和控制至关重要。已经提出了几个标量度量,但最近的重点转向网络结构,超越了一个简单的集合的二元相互作用,使他们无效的性能保证。本文引入了一种新的节点中心性度量,它不再是一个标量值,而是一个比超图中最高交互阶低一维的向量。这种向量测度与只包含二元交互的网络的特征向量中心性有关,但在所有其他高阶交互的情况下,它具有显著的附加值。特别是,它能够揭示不同的角色,可以由同一个节点在不同的互动顺序-信息,否则是不可能通过单一的标量措施检索。我们证明了我们的措施与应用程序的合成网络和三个现实世界的超图的有效性,并将我们的结果与文献中提出的中心性的其他标量措施所获得的结果进行比较。

英文摘要:

Identifying the most influential nodes in networked systems is of vital importance to optimize their function and control. Several scalar metrics have been proposed to that effect, but the recent shift in focus towards network structures which go beyond a simple collection of dyadic interactions has rendered them void of performance guarantees. We here introduce a new measure of node's centrality, which is no longer a scalar value, but a vector with dimension one lower than the highest order of interaction in a hypergraph. Such a vectorial measure is linked to the eigenvector centrality for networks containing only dyadic interactions, but it has a significant added value in all other situations where interactions occur at higher-orders. In particular, it is able to unveil different roles which may be played by the same node at different orders of interactions -- information that is otherwise impossible to retrieve by single scalar measures. We demonstrate the efficacy of our measure with applications to synthetic networks and to three real world hypergraphs, and compare our results with those obtained by applying other scalar measures of centrality proposed in the literature.
