Social network analysis (SNA) is the process of investigating social structures through the use of networks and graph theory. It characterizes networked structures in terms of "nodes" (individual actors, people, or things within the network) and the "ties", "edges", or "links" (relationships or interactions) that connect them. Social network analysis is prominent in Sociology, and its development has had a key role in the emergence of Learning Analytics.
