Although large language models (LLMs) can generate natural language summaries, they frequently lack domain-specific clinical grounding and struggle to produce factually correct and temporally consistent responses for structured longitudinal assessment data. To address these limitations, we propose MA-RAG, a query-driven multi-agent retrieval-augmented generation framework that decomposes clinical reasoning into domain-specialized agents, combines structured fact extraction, and synthesizes clinically grounded summaries through a final verification stage. The framework supports four clinical analysis tasks: single-session, trajectory, comparison, and cohort summarization. We evaluate MA-RAG using objective metrics, namely Fact Precision, Hallucination Rate, Temporal Fidelity, and Semantic Similarity, together with subjective evaluations conducted by clinical experts. Compared to Traditional, RAG-only, and Single-agent RAG baselines, MA-RAG substantially improves factual correctness, achieving up to a 122% relative increase in Fact Precision (from 0.436 to 0.990) and reducing the Hallucination Rate by up to 98% (from 0.564 to 0.010), while consistently receiving top ratings from clinical experts for organization and clinical usefulness. These results demonstrate that domain-specialized multi-agent reasoning enables reliable query-driven summarization of structured longitudinal clinical assessment data.", "url": "https://wpnews.pro/news/ma-rag-multi-agent-retrieval-augmented-generation-for-query-driven-summarization", "canonical_source": "https://arxiv.org/abs/2608.28624", "published_at": "2026-09-01 04:00:00+00:00", "updated_at": "2026-09-01 04:24:46.749895+00:00", "lang": "en", "topics": ["artificial-intelligence", "large-language-models", "generative-ai", "ai-research"], "entities": ["MA-RAG", "arXiv"], "alternates": {"html": "https://wpnews.pro/news/ma-rag-multi-agent-retrieval-augmented-generation-for-query-driven-summarization", "markdown": "https://wpnews.pro/news/ma-rag-multi-agent-retrieval-augmented-generation-for-query-driven-summarization.md", "text": "https://wpnews.pro/news/ma-rag-multi-agent-retrieval-augmented-generation-for-query-driven-summarization.txt", "jsonld": "https://wpnews.pro/news/ma-rag-multi-agent-retrieval-augmented-generation-for-query-driven-summarization.jsonld"}}
