Signed Network Modeling Based on Structural Balance Theory
The modeling of networks, specifically generative models, have been shown to provide a plethora of information about the underlying network structures, as well as many other benefits behind their construction. Recently there has been a considerable increase in interest for the better understanding and modeling of networks, but the vast majority of this work has been for unsigned networks. Howev...
متن کاملApplications of Structural Balance in Signed Social Networks
We present measures, models and link prediction algorithms based on the structural balance in signed social networks. Certain social networks contain, in addition to the usual friend links, enemy links. These networks are called signed social networks. A classical and major concept for signed social networks is that of structural balance, i.e., the tendency of triangles to be balanced towards i...
متن کاملComputing global structural balance in large-scale signed social networks.
Structural balance theory affirms that signed social networks (i.e., graphs whose signed edges represent friendly/hostile interactions among individuals) tend to be organized so as to avoid conflictual situations, corresponding to cycles of negative parity. Using an algorithm for ground-state calculation in large-scale Ising spin glasses, in this paper we compute the global level of balance of ...
متن کاملWalk-based measure of balance in signed networks: detecting lack of balance in social networks.
There is a longstanding belief that in social networks with simultaneous friendly and hostile interactions (signed networks) there is a general tendency to a global balance. Balance represents a state of the network with a lack of contentious situations. Here we introduce a method to quantify the degree of balance of any signed (social) network. It accounts for the contribution of all signed cy...
متن کاملHow do signs organize in directed signed social networks?
We introduce a reshuffled approach to empirical analyze signs’ organization in real directed signed social networks of Epinions and Slashdots from the global viewpoint. In the reshuffled approach, each negative link has probability prs to exchange its sign with another positive link chosen randomly. Through calculating the entropies of social status (Sin and Sout) of and mimicking opinion forma...
