Commonsense Knowledge Graph Reasoning by Selection or Generation? Why?

Understand

Commonsense knowledge graph reasoning(CKGR) is the task of predicting a missing entity given one existing and the relation in a commonsense knowledge graph (CKG).

• Existing methods can be classified into two categories generation method and selection method.
• Each method has its own advantage.
• We theoretically and empirically compare the two methods, finding the selection method is more suitable than the generation method in CKGR.
