Knowledge Graphs • Multiple types of edges • Each corresponds to a relation type • A set of facts, each of which is represented as a triplet • (Bill_Gates, CoFounder, Microsoft) friend?

Various Applications on Graphs • Predicting whether a user is a democratic or republican in Facebook? • Recommending friends in social networks • Predicting missing facts on knowledge graphs • Predicting the effective drugs for a target disease in a biomedical knowledge graph, a.k.a. drug repurposing • Predicting the chemical properties of molecules • … • Most of these applications require good feature representation of graphs!!
