referenceMulti-hop reasoning on massive knowledge graphs is a challenging task (Zhu et al. 2022) because most existing studies focus on smaller graphs with only 63K entities and 592K relations.
claimMulti-hop reasoning achieves more precise formation of triplets compared to single-hop prediction, making it a critical need for the development of knowledge graphs.
claimExisting multi-hop reasoning models cannot effectively learn from training sets for massive knowledge graphs containing millions of entities.
