STAIR (STructure Aware Information Retriever): A novel dataset and LLM based retriever for document structure augmentation
The insight that standard chunking discards valuable structural metadata is correct, and ToC-aware retrieval could help with the lost-in-the-middle problem. The reported 0.05% hallucination rate is encouraging but needs comparison to existing baselines to know if this is worth architectural changes to your RAG pipeline.
