MedMeta - Retrieved Abstracts (Top 5): leaderboard
The MedMeta meta-analysis conclusion task (Ha, Favre and Portet, 2026) with retrieval: for each of the model's sub-questions, the 5 best abstracts are retrieved by hybrid search and reranking from 25,000 PubMed abstracts, of which 2,250 are the true primary studies (81 meta-analyses). A panel of three LLM judges (Gemini 2.5 Pro, o4-mini, Qwen3-235B) scores each conclusion 0-5 for semantic equivalence to the original; higher is better.
Metric: LLM-judge score (0-5; mean of Gemini 2.5 Pro, o4-mini and Qwen3-235B judges rating semantic equivalence of the generated conclusion to the meta-analysis's own, 81 meta-analyses; Standard-RAG: 5 abstracts per sub-question from a 25,000-abstract corpus, hybrid search and reranker). Source: arxiv.org. Saturation forecast: Estimated already saturated. 7 models tracked.
