Description
Summary:A common but informal notion in social network analysis is the concept of a core/periphery structure. The intuitive conception entails a dense, cohesive core & a sparse, unconnected periphery. Here, the aim is to formalize this intuitive notion by suggesting algorithms for detecting network structure & statistical tests for testing a priori hypotheses. Different models are presented for different kinds of graphs (directed & undirected, valued & nonvalued). In addition, the close relation of the continuous models developed to certain centrality measures is discussed. 10 Tables, 4 Figures, 41 References. Adapted from the source document.
