HCRE improves cross-document relation extraction by having LLMs classify relations level-by-level down a tree structure while verifying predictions at each step to reduce errors.
Notably, the bag-level evaluation is essentially an- other form of path-level evaluation, requiring no additional model training or inference

HCRE: LLM-based Hierarchical Classification for Cross-Document Relation Extraction with a Prediction-then-Verification Strategy
HCRE improves cross-document relation extraction by having LLMs classify relations level-by-level down a tree structure while verifying predictions at each step to reduce errors.
