Structural and regular equivalence of community detection in social networks

The modern science of networks has brought significant advances to our understanding of complex systems. One of the most relative features of graphs representing in real systems is community detection. The community detection can be considered as fairly independent compartments of a graph and a similar role play. It is an important problem in the analysis of computer networks, social networks, biological networks and many other natural and artificial networks. Thus, these networks are in general very large. And the finding hidden structures and functional modules are very hard tasks. This problem is very hard and not yet satisfactorily solved. Many methods have been intended to deal with this problem in networks. Some of the most expectation are methods based on statistical inference, which support on solid mathematical foundations and return excellent results in practice. In this paper we show the blockmodeling, a collection of methods for partitioning networks according to well-specified criteria. We use the term “blockmodeling” to characterize the usual approach to blockmodeling, which based on the concepts of structural equivalence and regular equivalence. We also gives the idea about how community is detected in social networking by Euclidean distance algorithm and REGE algorithm.
