Interest graph
![Suppose two people have similar interests, such as photo and they like the same music. So there is a relationship between them based on their interests which can be shown by interest graph. Vertices correspond to entities, and edges are the relationships between entities.](/Images/godic/202501/20/Interest_graph1433.gif")
![Red edges are the part of an interest graph, where relations (red edges) could be between (1) user and interest and (2) between users. Blue edges are the part of a social graph, where there are relations only between users.](/Images/godic/202501/20/Interest_graph_vs_social_graph1433.png")
An interest graph is an online representation of the specific things in which an individual is interested. Interest graphs have perceived utility and value because of the premise that people’s interests are a major aspect of who they are, forming part of their personal identity, and can be used as indicators of such things as what they might want to do or buy, where they might want to go, or who they might want to meet, follow or vote for.
