Evaluation of graph centrality measures for tweet classification

- Computer Science
- 2016 International Conference on Computing, Electronic and Electrical Engineering (ICE Cube)
- 2016

This paper explores the utilization of graph centrality measures to classify tweets accuracy and tests the resulting technique by classifying Twitter messages in belonging to trending topic of #eq2015 and then classifying them in subtopics based on geographical information. Expand

Advanced spatial network metrics for cognitive management of 5G networks

- Computer Science
- Soft Comput.
- 2021

This new framework, centred on a topology monitoring agent (TMA), enables on-demand 5G networks’ spatial knowledge and topological awareness required by 5G cognitive network management in making smart decisions in various autonomous network management tasks including but not limited to virtual network function placement strategies.

Approximation of Interactive Betweenness Centrality in Large Complex Networks

- Computer Science
- Complex.
- 2020

This study addresses the research questions, whether approximations of interactive betweenness centrality can be obtained with reduction of computational costs and how much quality/accuracy needs to be traded in order to obtain a significant reduction. Expand

Axioms for Distance-Based Centralities

- Computer Science
- AAAI
- 2018

This work proposes the class of additive distance-based centralities and pin-point properties which combined with the axiomatic characterization of the whole class uniquely characterize a number of centralities from the literature. Expand

Measuring centrality by a generalization of degree

- Mathematics, Computer Science
- Central Eur. J. Oper. Res.
- 2017

A new parametric family of centrality measures called generalized degree is proposed, based on the idea that a relationship to a more interconnected node contributes to centrality in a greater extent than a connection to a less central one. Expand

The Degree Measure as Utility Function over Positions in Networks

- Mathematics
- 2017

In this paper, we connect the social network theory on centrality measures to the economic theory of preferences and utility. Using the fact that networks form a special class of cooperative… Expand

A Authentication model to Trustees based Social Networks

- Engineering
- 2016

authenticating users with the help of their friends has been shown to be a promising backup authentication mechanism. A user in this system is associated with a few trustees that were selected from… Expand

A Hierarchical Pseudonyms Management Approach for Software-Defined Vehicular Networks

- Engineering, Computer Science
- 2016 IEEE 83rd Vehicular Technology Conference (VTC Spring)
- 2016

This work uses two-sided matching theory to solve the pseudonym resources allocation problem among pseudonym pools in different roadside unit clouds and shows that the proposed approach optimizes the pseudonym Resources utilization and also improves the privacy entropy of vehicles. Expand
