One of the issues of social science is the analysis of why and how human relationships are formed. The causes of these phenomena are explained by structural balance theory and status theory, among others. Although the structural balance model by Antal et al. is a breakthrough in modeling the formation of social relationship structures, but by the diverse nature of positive and negative relationships in real-world social networks, it is unable to capture a complete picture of the relationships between users of different online communities. In addition to stability as understood by Heider’s hypothesis, which is contained in structural balance theory, dynamics based on social status should also be taken into account.
We present two new models: an extended model of structural balance on directed networks and a model combining dynamics of structural balance and status theories. Presented numerical simulation results are consistent with analytical expectations. The theoretical observations have been verified on real networks, where the effect of status on the relationship between users of the studied websites has been noticed.
