SPIMP-RAG: structure-prior injected message passing for low-budget triple retrieval in LLM-based knowledge graph question answering

SPIMP-RAG is proposed, a coarse-to-fine triple retrieval approach whose key component is Structure-Prior Injected Message Passing (SPIMP), a fine-stage reranker that injects Directional Distance Encoding into relation-aware message passing and supports the effectiveness of structure-aware fine reranking for compact evi...

DuoFlow-KG: a dual-modal evidence retrieval framework for high-density LLM-augmented KGQA.

This work proposes DuoFlow-KG, a unified dual-modal evidence retrieval framework that constructs compact, high-density evidence subgraphs through integrated structure-semantic modeling and introduces a dual-directional knowledge anchoring strategy that enriches entity representations by incorporating both incoming and...
