介数已被用于一些海洋研究,以确定部分的海洋,维持整个海洋网络的连接。在这里,我们强调的方法的准确性,在计算介数时,图论应用于海洋连通性研究的基础上转移概率的需要。我们表明,直接从传输概率计算介数的不一致性,并提出了一个新的度量的节点到节点的距离,解决it.Our论证说明了两个简单的理论例子和文献数据集的分析。
Betweenness has been used in a number of marine studies to identify portions of sea that sustain the connectivity of whole marine networks. Herein we highlight the need of methodological exactness in the calculation of betweenness when graph theory is applied to marine connectivity studies based on transfer probabilities. We show the inconsistency in calculating betweeness directly from transfer probabilities and propose a new metric for the node-to-node distance that solves it. Our argumentation is illustrated by both simple theoretical examples and the analysis of a literature data set.
