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 ...

Centrality Learning: Auralization and Route Fitting

open access: yesEntropy, 2023
Developing a tailor-made centrality measure for a given task requires domain- and network-analysis expertise, as well as time and effort. Thus, automatically learning arbitrary centrality measures for providing ground-truth node scores is an important ...

Redundancy of Centrality Measures in Financial Market Infrastructures

open access: yesLatin American Journal of Central Banking, 2023
The concept of centrality is widely used to monitor systems with a network structure because it allows identifying their most influential participants. This monitoring task can be difficult if the number of system participants is considerably large or if

Sampling on networks: estimating spectral centrality measures and their impact in evaluating other relevant network measures

open access: yesApplied Network Science, 2020
We perform an extensive analysis of how sampling impacts the estimate of several relevant network measures. In particular, we focus on how a sampling strategy optimized to recover a particular spectral centrality measure impacts other topological ...

Street centrality and land use intensity in Baton Rouge, Louisiana [PDF]

open access: yes, 2011
This paper examines the relationship between street centrality and land use intensity in Baton Rouge, Louisiana. Street centrality is calibrated in terms of a node's closeness, betweenness and straightness on the road network.

An Experimental Study on Centrality Measures Using Clustering

open access: yesComputers, 2021
Graphs can be found in almost every part of modern life: social networks, road networks, biology, and so on. Finding the most important node is a vital issue.

Efficient computation of the Shapley value for game-theoretic network centrality [PDF]

open access: yes, 2013
The Shapley value—probably the most important normative payoff division scheme in coalitional games—has recently been advocated as a useful measure of centrality in net-works.

Centrality Measures in Directed Fuzzy Social Networks

open access: yesFuzzy Information and Engineering, 2015
The centrality of actors has been a key issue in undirected fuzzy social network (UFSN) analysis. For undirected fuzzy social networks (UFSNs) where edges are just a present or absent undirected fuzzy relation with no more information attached. There has

Correlation between student collaboration network centrality and academic performance

open access: yesPhysical Review Physics Education Research, 2018
We compute nodal centrality measures on the collaboration networks of students enrolled in three upper-division physics courses, usually taken sequentially, at the Colorado School of Mines.

Map equation centrality: community-aware centrality based on the map equation

open access: yesApplied Network Science, 2022
To measure node importance, network scientists employ centrality scores that typically take a microscopic or macroscopic perspective, relying on node features or global network structure. However, traditional centrality measures such as degree centrality,
