Extended Generalized Blockmodeling for Compound Communities and External Actors

Abstract

Some social communities evident their own unique internal structure. In this chapter, we consider social communities composed of several cohesive subgroups which we call compound communities. For such communities, an extended generalized blockmodeling is proposed, taking into account the structure of compound communities and their relations with external actors. Using the extension, the community protection approach is proposed and used in detection of spam directed toward an e-mail local society.
