Generalization of Relative Change in a Centrality Measure to Identify Vital Nodes in Complex Networks

open access: yesIEEE Access, 2023
Identifying vital nodes is important in disease research, spreading rumors, viral marketing, and drug development. The vital nodes in any network are used to spread information as widely as possible.

An Analysis of Centrality’s Features as a New Measure for Network Analysis, Risk Measurement & Portfolio Selection [PDF]

open access: yesتحقیقات مالی, 2021
Objective: In network theory, centrality is a measure to estimate importance and influence of a special node to the whole network structure. The aim of this research is to investigate the characteristics of stock centrality and its reliability in risk ...

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 ...

Interplay Between Hierarchy and Centrality in Complex Networks

open access: yesIEEE Access, 2020
Hierarchy and centrality are two popular notions used to characterize the importance of entities in complex systems. Indeed, many complex systems exhibit a natural hierarchical structure, and centrality is a fundamental characteristic allowing to ...

A COMPARISON OF CENTRALITY MEASURES IN SUSTAINABLE DEVELOPMENT GOALS

open access: yesBarekeng, 2020
The Millennium Development Goals (MDGs), which began in 2000 with 8 goal points, have not been able to solve the global problems. The MDGs were developed into Sustainable Development Goals (SDGs) in 2015 with 17 targeted goal points achieved in 2030 ...

Dynamic centrality measures for cattle trade networks

open access: yesApplied Network Science, 2021
We study network centrality measures that take into account the specific structure of networks with time-stamped edges. In particular, we explore how such measures can be used to identify nodes most relevant for the spread of epidemics on directed ...

Bipolar-Valued Fuzzy Social Network and Centrality Measures

open access: yesDiscrete Dynamics in Nature and Society, 2022
The concept of bipolar-valued fuzzy relationships and their role in modeling bipolar-valued fuzzy social networks (BVFSN) are discussed. The goal of this study is to represent the bipolarity and fuzziness that are always present in the relationship ...
