Predicate Importance Estimation and Decoupled Rationale-Score Distillation for Entity Alignment

Keunha Kim, Yoonjin Jang, Hyeon-gu Lee +2

Knowledge graphs (KGs) are increasingly used as structured context for Large Language Models (LLMs), but industrial KG-RAG systems often need to integrate public and domain-specifi…

HELEA: Hard-Negative Benchmark and LLM-based Reranking for Robust Entity Alignment

Yoonjin Jang, Junwoo Kim, Youngjoong Ko

Entity Alignment (EA) is essential for knowledge graph (KG) fusion, but existing benchmarks often allow models to exploit name overlap rather than relational structure. This makes…
