Abstract: | Social networks in communities, markets, and societies self-organise through the interactions of many individuals. In this
paper we use a well-known
mechanism of social interactions — the balance of sentiment in triadic
relations — to describe the development of social networks. Our model
contrasts with many existing network models, in that people not only
establish but also break up relations whilst the network evolves. The
procedure generates several interesting network features such as a variety
of degree distributions and degree correlations. The resulting network
converges under certain conditions to a steady critical state where temporal
disruptions in triangles follow a power-law distribution. |
