Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Evaluated with the RAGAS framework on 52 expert-developed question-answer pairs, the system retrieved sufficient clinical content (context recall above 0.93) and generated responses closely aligned with query intent (answer relevance 0.87). → Ronghua Xu 2026

q2 · i? · design · r2
RAGAS evaluation of the prototype's RAG assistant on 52 question-answer pairs developed by medical professionals, categorized as basic, medium, and advanced. The article reports context recall "above 0.93" and separately an answer relevance score of 0.87; answer completeness was consistently high across configurations.
"We found that recall successfully captured the required information to answer the question, with a score above 0.93 showing a strong retrieval capacity for retrieving sufficient clinical content."
Discussion¶
Related Claims¶
- Retrieval augmentation is essential for on-premise educational QA: a local LLM without retrieval scores below even a TF-IDF baseline — related
- Research-question responses score higher Answer Relevancy (0.87) than follow-ups (0.72), while Faithfulness, Context Relevance and Response Groundedness are lower — related
