Data Characteristics for This Category
Health insurance access documents primarily include pharmacoeconomic evaluation reports, drug clinical trial reports, drug package inserts, National Medical Products Administration (NMPA) approval documents, and National Healthcare Security Administration (NHSA) catalog adjustment application materials. These documents are typically in PDF, Word, or structured database formats. Data sources include the official NMPA website, official NHSA website, provincial/municipal drug procurement platforms, and internal research reports and market analyses generated by pharmaceutical companies. Regarding update frequency, the NHSA catalog is usually adjusted annually, provincial/municipal drug procurement policies update at varying frequencies, and internal pharmaceutical company reports are generated dynamically based on R&D and market progress. Document structures are complex, containing extensive specialized terminology, data charts, and cited literature. Economic and clinical reports are often lengthy, with fields covering drug generic names, indications, dosages, specifications, manufacturers, health insurance payment standards, inclusion/exclusion criteria, clinical efficacy data, adverse event rates, and cost-benefit ratios.
Constraints Imposed by These Characteristics on "Reference Sourcing and Traceability"
The complexity and high compliance requirements of health insurance access documents place stringent demands on reference sourcing and traceability. Their multi-source heterogeneous data characteristics mean the knowledge base must integrate information from different formats and sources while maintaining the validity of original reference links. Annual or irregular policy and catalog updates require the knowledge base to have efficient incremental update and version management capabilities, ensuring the timeliness of references. The precise numerical values, statistical results, and medical terminology contained in documents dictate that references must point to specific paragraphs or charts in the original text to support the rigor of application materials. Furthermore, the sensitivity of health insurance payment standards and the criticality of clinical data mean that any reference must be traceable to authoritative sources, avoiding compliance risks or application failures due to inaccurate citations.
Configuration Settings
| Configuration Item | Recommended Value | Rationale for Recommendation |
|---|---|---|
Recall count (Recall Count) | 5-8 entries (5-8 items) | Health insurance data is highly specialized and requires in-depth comparison; increasing recall appropriately enhances relevance coverage. |
Similarity threshold (Similarity Threshold) | 0.78-0.85 | Ensures the precision of recalled content, preventing low-relevance information from interfering with professional judgment. |
Chunk size (Segment Length) | 400-600 characters (400-600 characters) | Balances semantic completeness with recall efficiency, avoiding long paragraphs diluting key information and short paragraphs fragmenting it. |
Rerank result count (Reranked Return Count) | 3-5 entries (3-5 items) | Further optimizes sorting based on initial recall, focusing on the most core references. |
maxContext | 3000-4000 token | Health insurance data has close contextual relationships; a sufficiently long context is needed to support understanding and referencing. |
Reference Link Mode | Show source link only | Ensures references point directly to original authoritative documents, meeting compliance and traceability requirements. |
Three Common Mistakes
- Dialogue includes reference items unrelated to the application topic. This occurs because the
Similarity threshold(Similarity Threshold) is set too low, leading to the recall of non-core content. - The referenced source document version is not the latest, potentially causing application materials to be based on outdated policies. This happens when the knowledge base update mechanism fails to synchronize with official releases in a timely manner.
- Cited content only displays the document name and cannot jump to specific paragraphs. This is due to a lack of deep parsing during document processing, missing anchor information in the
Reference Link Modeconfiguration.
How to Confirm Proper Configuration
- Select a real question from a recent health insurance access application. Simulate the query in the system and check if all returned references originate from authoritative sources.
- Choose a document containing complex charts or specific health insurance payment standards. Upload it to the knowledge base, then query it, verifying that references can accurately locate the charts or numerical values within paragraphs.
- After a system update, randomly select several key policy queries. Verify that the version numbers of the referenced documents match the latest official releases.
