A study of sign adjustment in weighted signed networks

Social Networks, 2012
Abstract We analyse the adjustment of networks comprising of weighted positive (P) and negative (N) symmetric relations under the impact of various balancing rules. Five kinds of rules are studied: (1) a local minimal edge adjustment which is a special case of, (2) a local pressure based rule, (3) a local sign based rule, (4) a global rule and (5 ...

Edge controllability of signed networks

Automatica, 2023
The edge controllability of signed networks, where the dynamics taking place on edges and the interaction type over each edge can be cooperative or antagonistic is studied in this manuscript using graph-theoretic perspective. Then the lower and upper bounds for the dimension of edge controllable subspace are discussed, respectively.The relationship ...

On the Network Embedding in Sparse Signed Networks

2019
Network embedding, that learns low-dimensional node representations in a graph such that the network structure is preserved, has gained significant attention in recent years. Most state-of-the-art embedding methods have mainly designed algorithms for representing nodes in unsigned social networks.

Laplacian dynamics on signed networks

2016 IEEE 55th Conference on Decision and Control (CDC), 2016
In this paper, we examine the properties of the Laplacian matrix defined on signed networks, referred to as the signed Laplacian matrix, from a graph-theoretic perspective. The connection between the stability of the signed Laplacian with the cut set of the network is established. This is then followed by relating and the number of negative eigenvalues

Prediction in signed heterogeneous networks

Proceedings of the 2014 IEEE 18th International Conference on Computer Supported Cooperative Work in Design (CSCWD), 2014
The problem of prediction is an important task in network analysis, which has attracted more attention from computer science communities. In this paper, prediction in signed heterogeneous networks is addressed, which contains two aspects, link prediction and sign prediction.

Social balance in signed networks

Information Systems Frontiers, 2014
The theory of social balance, also called structural balance, is first proposed by Heider in 1940s, which is utilized to describe the potential social dynamics process. This theory is of great importance in sociology, computer science, psychology and other disciplines where social systems can be represented as signed networks.

Modelling weighted signed networks

2019
In this paper we introduce a new modelling approach to analyse weighted signed networks by assuming that their generative process consists of two models: the interaction model which describes the overall connectivity structure of the relations in the network without taking into account neither the weight nor the sign of the dyadic relations; and the ...

Single Sign-on and Social Networks

IEEE Distributed Systems Online, 2008
Call it what you will - single sign-on, federated identity, one-stop authentication - letting users sign on to the Internet once and securely access network resources anywhere has been one of the industry's enduring quests.

Attributed Signed Network Embedding

Proceedings of the 2017 ACM on Conference on Information and Knowledge Management, 2017
The major task of network embedding is to learn low-dimensional vector representations of social-network nodes. It facilitates many analytical tasks such as link prediction and node clustering and thus has attracted increasing attention. The majority of existing embedding algorithms are designed for unsigned social networks.

DSP: Deep Sign Prediction in Signed Social Networks

2020
In a signed social network, users can express emotional tendencies such as: like/dislike, friend/foe, support/oppose, trust/distrust to others. Sign prediction, which aims to predict the sign of an edge, is an important task of signed social networks. In this paper, we attempt to tackle the problem of sign prediction by proposing a Deep Sign Prediction
