NGM-RAG: Neural Graph Matching based Retrieval-Augmented Generation

Published in The 23rd CCF Conference on Web Information Systems and Applications, 2026

NGM-RAG is a novel RAG framework combined with graph structure, which improves the retrieval and generation effects in multi-hop reasoning and complex question-answering tasks by integrating multiple matching methods.

LiR^3AG: A Lightweight Rerank Reasoning Strategy Framework for Retrieval-Augmented Generation

Published in The Association for the Advancement of Artificial Intelligence, 2026

We explored the reasoning strategies of reasoning models in RAG multi-hop QA tasks, finally proposed a lightweight framework that improves performance while significantly reducing reasoning overhead by integrating three modules.
