Data Characteristics
Drug registration and declaration documents originate from sources such as drug inserts published by the National Medical Products Administration (NMPA), clinical trial data reports, pharmacology and toxicology research reports, authoritative domestic and international medical guidelines, pharmacopoeias, and adverse reaction monitoring data. This data exists in both structured (e.g., clinical trial databases, drug registration databases) and unstructured (e.g., PDF literature, Word document guidelines) formats. Update frequency varies: drug inserts and adverse reaction data are updated irregularly based on post-market surveillance, while medical guidelines have fixed revision cycles, typically ranging from months to several years. Document structures are complex, containing numerous specialized terms, dosage units (e.g., mg, g, IU), administration routes (oral, injection), indications, contraindications, and drug interactions.
Constraints on Multi-turn Conversations and Prompts
The complex structure and specialized terminology of drug information require precise semantic understanding in multi-turn conversation systems. The system must identify and differentiate key information such as drugs, dosages, and indications. Frequent updates to drug inserts mean the knowledge base needs efficient version management and incremental updates to ensure information timeliness. Unstructured documents present challenges for text extraction and structuring, requiring accurate information retrieval. Medical guidelines often include recommendation and evidence levels; the conversation system must understand these hierarchical relationships and reflect them appropriately in responses to avoid misinformation. For coherent multi-turn conversations, the system needs to remember context such as drug names and patient characteristics to provide personalized drug use advice.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000 tokens | Accommodates the length and specialized terminology density of medical literature, ensuring complete context. |
Chunk size (Segment Length) | 500 characters (characters) | Balances semantic completeness with recall efficiency, avoiding redundant information in long paragraphs. |
Recall count (Recall Count) | Top 8 entries (top 8) | Increases coverage of relevant information to address cross-references in medical knowledge. |
Similarity threshold (Similarity Threshold) | 0.75 | Balances recall accuracy and breadth, reducing interference from irrelevant information. |
Rerank result count (Rerank Return Count) | Top 3 entries (top 3) | Highlights the most relevant core information, optimizing final display. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds (seconds) | Accommodates parsing times for large PDF medical guidelines and clinical reports. |
Common Pitfalls
- Conversation logs show "API call failed: connection timeout." This occurs when the system attempts to call an external database or API for the latest drug information, but network latency or slow service response causes a timeout.
- A user asks about the dosage of a drug for patients with renal impairment, but the response provides a normal dosage. This happens when detailed rules or data regarding medication for special populations are not sufficiently indexed or understood in the knowledge base.
- Drug names or dosage units appear as garbled characters in streaming output. This typically results from an inconsistency between the data source encoding and the system's processing encoding.
Verification
- Conduct multi-turn conversation tests across various typical drug use scenarios. Check for smooth conversation flow and accurate identification and citation of key information (e.g., drug names, dosages, contraindications).
- Randomly select recently updated drug inserts or guidelines from the knowledge base. Ask related questions and verify that system responses align with the latest document content.
- Review system logs for API call timeouts, data parsing errors, or encoding anomalies. Adjust
PARSE_FILE_TIMEOUT_SECONDSor data encoding settings as indicated. - Simulate complex drug interaction questions. Observe if the system can synthesize information from multiple drugs and provide reasonable advice. Evaluate the effectiveness of
