Generative Representation Learning on Hyper-relational Knowledge Graphs via Masked Discrete Diffusion
Researchers have developed KREPE, a novel method for generative representation learning on hyper-relational knowledge graphs (HKGs). This approach addresses the limitation of existing methods by enabling the generation of entire facts, even when multiple components are missing, rather than just predicting single links. KREPE utilizes masked discrete diffusion to model dependencies within facts and correlations between them, achieving state-of-the-art performance on link prediction tasks and outperforming large language models in generating novel facts.
