ClinicBot用结构化证据优先排序,让AI给出有据可查的临床建议。
ClinicBot: A Guideline-Grounded Clinical Chatbot with Prioritized Evidence RAG and Verifiable Citations

- 将指南拆解为推荐、表格等语义单元,每条都有来源追踪
- 按临床重要性而非文字相似度排序证据,减少无关信息干扰
- 适合医生或医学生查指南,支持真实患者问诊场景
临床诊断需要准确、可验证且明确基于官方指南的答案。尽管大语言模型在自然语言处理方面表现优异,但其容易产生幻觉,在对精度要求极高的医疗场景中会削弱实用性。现有检索增强生成(RAG)系统将所有证据同等对待,导致上下文噪声多、回答泛化,与临床实践脱节。我们提出ClinicBot,一种通过三方面改进实现可信临床支持的AI系统:(1) 将临床指南结构化提取为语义单元(如推荐、表格、定义、叙述),并保留明确出处;(2) 基于临床重要性和指南结构而非文本相似性进行证据优先级排序;(3) 提供基于网页的界面,呈现简洁、可操作的答案,并附可验证证据。我们将通过真实患者关于糖尿病的问题,以及一个符合美国糖尿病协会(ADA)《糖尿病标准护理》(2025年版)的糖尿病风险评估工具演示ClinicBot。展示表明,语义知识提取与分层证据排序可在多智能体设置下可靠运行,实现对复杂临床指南的大规模处理。
原文摘要 · Abstract (English)
Clinical diagnosis requires answers that are accurate, verifiable, and explicitly grounded in official guidelines. While large language models excel at natural language processing, their tendency to hallucinate undermines their utility in high-stakes medical contexts where precision is essential. Existing retrieval-augmented generation (RAG) systems treat all evidence equally, producing noisy context and generic answers misaligned with clinical practice. We present ClinicBot, an AI system that translates guideline recommendations into trustworthy clinical support through three key advances: (1) structured extraction of clinical guidelines into semantic units (recommendations, tables, definitions, narrative) with explicit provenance, (2) evidence prioritization that ranks content by clinical significance and guideline structure rather than textual similarity, and (3) a web-based interface that presents concise, actionable answers with verifiable evidence. We will demonstrate ClinicBot using diabetes questions from real patients and an additional diabetes risk assessment tool that is faithful to the American Diabetes Association (ADA) Standards of Care in Diabetes (2025). The demonstration will illustrate how semantic knowledge extraction and hierarchical evidence ranking can reliably operate in a multi-agent setting to process complex clinical guidelines at scale.
