NaviRAG: Towards Active Knowledge Navigation for Retrieval-Augmented Generation

In three linesNaviRAG introduces a RAG framework shifting from passive segment retrieval to active knowledge navigation. The system structures documents into semantic hierarchies and uses an LLM agent to iteratively navigate, identify information gaps, and retrieve content at appropriate granularity levels. Results show improved retrieval recall and QA performance on long-document benchmarks over conventional RAG.
