Centrality measures in networks

open access: yesSocial Choice and Welfare, 2023
We show that prominent centrality measures in network analysis are all based on additively separable and linear treatments of statistics that capture a node's position in the network. This enables us to provide a taxonomy of centrality measures that distills them to varying on two dimensions: (i) which information they make use of about nodes ...

Comparison-based centrality measures [PDF]

open access: yesInternational Journal of Data Science and Analytics, 2021
AbstractRecently, learning only from ordinal information of the type “itemxis closer to itemythan to itemz” has received increasing attention in the machine learning community. Such triplet comparisons are particularly well suited for learning from crowdsourced human intelligence tasks, in which workers make statements about the relative distances in a

Total communicability as a centrality measure [PDF]

open access: yesJournal of Complex Networks, 2013
We examine a node centrality measure based on the notion of total communicability, defined in terms of the row sums of the exponential of the adjacency matrix of the network. We argue that this is a natural metric for ranking nodes in a network, and we point out that it can be computed very rapidly even in the case of large networks.

The measurement of Central Corneal Thickness

open access: yesromanian journal of ophthalmology, 2023
We aimed to compare five different devices that measure Central Corneal Thickness. The Central Corneal Thickness (CCT) is an important parameter in ophthalmology. It is involved in the management of various eye conditions such as: glaucoma, keratoconus, contact lens wearing, corneal dystrophies, refractive surgery and keratoplasty.

Potential gain as a centrality measure [PDF]

open access: yesIEEE/WIC/ACM International Conference on Web Intelligence, 2019
Navigability is a distinctive features of graphs associated with artificial or natural systems whose primary goal is the transportation of information or goods. We say that a graph $\mathcal{G}$ is navigable when an agent is able to efficiently reach any target node in $\mathcal{G}$ by means of local routing decisions.

A study of the stability of information and telecommunication networks under conditions of stochastic percolation of nodes [PDF]

open access: yesНаучно-технический вестник информационных технологий, механики и оптики, 2021
In-depth studies of the topological properties of information and telecommunication networks contribute to the understanding of their functional capabilities, including stability.

X-index: A novel flow-based locational measure for quantifying centrality

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2023
The centrality of a place reflects its relative importance in serving other places, and quantifying centrality is a prerequisite for assessing the urban spatial structure and facilitates policy-making of sustainable urban development.

Scale-dependent measure of network centrality from diffusion dynamics

open access: yesPhysical Review Research, 2020
Classic measures of graph centrality capture distinct aspects of node importance, from the local (e.g., degree) to the global (e.g., closeness). Here we exploit the connection between diffusion and geometry to introduce a multiscale centrality measure. A

A measure of centrality in cyclic diffusion processes: Walk-betweenness.

open access: yesPLoS ONE, 2021
Unlike many traditional measures of centrality based on paths that do not allow any repeated nodes or lines, we propose a new measure of centrality based on walks, walk-betweenness, that allows any number of repeated nodes or lines.

Strategic Evasion of Centrality Measures

open access: yesInternational Joint Conference on Autonomous Agents and Multiagent Systems, 2021
Among the most fundamental tools for social network analysis are centrality measures, which quantify the importance of every node in the network. This centrality analysis typically disregards the possibility that the network may have been deliberately manipulated to mislead the analysis. To solve this problem, a recent study attempted to understand how
