Working with Graphs: Pre-training and Application
Xuzeng He · 2024
Introduction A graph, in short, is a description of items linked by relations, where the items of a graph are called nodes (or vertices) and their relations are called edges (or links). Examples of graphs can include social networks (e.g. Instagram) or knowledge graphs (e.g. Wikipedia). In Instagram for instance, a graph might be used to represent users as nodes and their relationships(who follows whom) as edges.
