Detailed paper with a lot of smart thinking about graphs and learning analytics. A graph is, in a nutshell, a set of connections between entities (or in graphspeak, a set of edges and nodes). "In this paper, Social Learning Graphs are presented as a framework to capture and represent the interactions and relations occurring among multiple entities in a learning environment. The advantage of this representation is that it combines structural in formation with observations in a common graph notation suitable to be used by procedures such as link-prediction, recommendation, and abstractions."
