A corrective agentic hybrid RAG and an operations-grounded evaluation for a scientific facility

- What happened
- Researchers deployed APS-RAG, a retrieval-augmented generation system combining dense, sparse, and knowledge-graph search channels with a corrective agentic loop for querying scientific facility operational knowledge.
- Why it matters
- Matters for engineers at large research facilities who need to search decades of accumulated operational data including logbooks, maintenance records, and control-system information through natural language.
- Watch out
- Performance gains from graph channels and corrective loops were marginal; cross-encoder reranking proved critical, and the system was evaluated on only fifty questions specific to one facility.
