Message passing optimization of Harmonic Influence Centrality [PDF]

open access: yes, 2014
This paper proposes a new measure of node centrality in social networks, the Harmonic Influence Centrality, which emerges naturally in the study of social influence over networks.

Knotty-centrality: finding the connective core of a complex network. [PDF]

open access: yesPLoS ONE, 2012
A network measure called knotty-centrality is defined that quantifies the extent to which a given subset of a graph's nodes constitutes a densely intra-connected topologically central connective core. Using this measure, the knotty centre of a network is

Computing Influential Nodes Using the Nearest Neighborhood Trust Value and PageRank in Complex Networks

open access: yesEntropy, 2022
Computing influential nodes gets a lot of attention from many researchers for information spreading in complex networks. It has vast applications, such as viral marketing, social leader creation, rumor control, and opinion monitoring.

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

Centrality Measures in Networks [PDF]

open access: yesSSRN Electronic Journal, 2016
We show that although the prominent centrality measures in network analysis make use of different information about nodes' positions, they all process that information in an identical way: they all spring from a common family that are characterized by the same simple axioms.

Measurement of Central Tendencies

open access: yesJournal for Research in Applied Sciences and Biotechnology, 2023
The main purpose of this article is to understand central tendencies, its application, its types, as well as to learn how to achieve arithmetic mean from grouped and ungrouped data. We will be able to understand geometric and harmonic means and way to calculate them from grouped and ungrouped data.

Evaluating Influential Nodes in Social Networks by Local Centrality with a Coefficient

open access: yesISPRS International Journal of Geo-Information, 2017
Influential nodes are rare in social networks, but their influence can quickly spread to most nodes in the network. Identifying influential nodes allows us to better control epidemic outbreaks, accelerate information propagation, conduct successful e ...

PERFORMANCE EVALUATION OF BETWEENNESS CENTRALITY USING CLUSTERING METHODS

open access: yesStudia Universitatis Babes-Bolyai: Series Informatica, 2020
Betweenness centrality measure is used as a general measure of centrality, which can be applied in many scientific fields like social networks, biological networks, telecommunication networks or even in any area that can be well modelled using complex ...

Localization and centrality in networks

open access: yes, 2014
Eigenvector centrality is a common measure of the importance of nodes in a network. Here we show that under common conditions the eigenvector centrality displays a localization transition that causes most of the weight of the centrality to concentrate on
