Balance and frustration in signed networks [PDF]

open access: yesJournal of Complex Networks, 2018
The frustration index is a key measure for analysing signed networks, which has been underused due to its computational complexity. We use an exact optimisation-based method to analyse frustration as a global structural property of signed networks coming from diverse application areas.

Signed networks in social media [PDF]

open access: yesProceedings of the SIGCHI Conference on Human Factors in Computing Systems, 2010
Relations between users on social media sites often reflect a mixture of positive (friendly) and negative (antagonistic) interactions. In contrast to the bulk of research on social networks that has focused almost exclusively on positive interpretations of links between people, we study how the interplay between positive and negative relationships ...

Bipartite Consensus Problems on Second-Order Signed Networks With Heterogeneous Topologies

open access: yesIEEE Access, 2020
This paper is devoted to the convergence problem for second-order signed networks that are associated with two signed graphs in the presence of heterogeneous topologies.

Balance in signed networks

open access: yesPhysical Review E, 2019
We consider signed networks in which connections or edges can be either positive (friendship, trust, alliance) or negative (dislike, distrust, conflict). Early literature in graph theory theorized that such networks should display "structural balance," meaning that certain configurations of positive and negative edges are favored and others are ...

Link prediction in multiplex online social networks [PDF]

open access: yesRoyal Society Open Science, 2017
Online social networks play a major role in modern societies, and they have shaped the way social relationships evolve. Link prediction in social networks has many potential applications such as recommending new items to users, friendship suggestion and ...

Enhanced Signed Graph Neural Network with Node Polarity

open access: yesEntropy, 2022
Signed graph neural networks learn low-dimensional representations for nodes in signed networks with positive and negative links, which helps with many downstream tasks like link prediction.

Signed Graph Convolutional Networks

open access: yes2018 IEEE International Conference on Data Mining (ICDM), 2018
Due to the fact much of today's data can be represented as graphs, there has been a demand for generalizing neural network models for graph data. One recent direction that has shown fruitful results, and therefore growing interest, is the usage of graph convolutional neural networks (GCNs). They have been shown to provide a significant improvement on a

Delineating Changes in the Fundamental Structure of Signed Networks

open access: yesFrontiers in Physics, 2020
We tackle two problems. One is understanding parts of the operation of the US Supreme Court. The other is a fundamental problem for network analysis. It is delineating the fundamental structures of networks.
