In Social Network Analysis (SNA), one of the key issues is to understand the structure of the network by identifying different groups (communities) within a larger set of nodes. After discussing concepts such as centrality (the importance of a node in the network) and structural holes (places that can be bridges between different groups), we move on to the analysis of clusters and subnetworks. Both concepts allow us to better understand how networks organize themselves into subgroups and how these groups affect the entire system.
