Healthcare Appointment Retrieval Architecture for Fresh, Traceable Appointment Answers

说明与用途

医疗预约助手的检索架构通过硬过滤、分阶段搜索和明确的排名信号，提供最新、可追溯的答案。

问题

A healthcare appointment assistant must provide answers that are current, relevant, and traceable to authoritative sources, avoiding stale or irrelevant policy text.

结果

The architecture guarantees that appointment answers are based on up‑to‑date, tenant‑specific policies, with evidence traceable to source documents, improving safety and auditability.

工作流

• 1. Filter candidates by tenant, locale, appointment type, and effective date.
• 2. Merge results from a narrow web search and an indexed vector collection.
• 3. Rank merged candidates by validity, scope, freshness, semantic similarity, and evidence quality.
• 4. Pass only bounded, cited context to the answer model.
• 5. Include source URL or document ID and retrieval timestamp in the prompt.
• 6. If no traceable source is found, ask for clarification or hand off.

证据

Start with hard gates. Filter by tenant, locale, appointment type, and effective date before applying semantic similarity.

来源

After the gates, combine signals in an order that an evaluator can inspect: 1. Validity 2. Scope 3. Freshness 4. Semantic score 5. Evidence quality.

来源

The final prompt should include the source URL or document identifier beside each chunk, plus the retrieval timestamp.
