Note on retrieval metrics (NDCG@5, MRR, Precision@5, Recall@5): These values appear low because the golden evaluation framework defines expected_source_urls at a coarse level (e.g. /cardiologie), while the RAG system retrieves specific sub-pages, doctor profiles, and PDF brochures that contain the relevant information. Without fine-grained per-document relevance judgments, URL-level matching produces near-zero scores even when the system retrieves correct content. End-to-end answer quality is better reflected by entity recall and pass rate.

Statistical Analysis

95% bootstrap confidence intervals (10,000 resamples, percentile method). Narrower intervals indicate more reliable estimates.
