Data Characteristics
R&D documents in cardiovascular intervention primarily come from clinical trial reports, device design specifications, regulatory approval materials, and academic research papers. These data update infrequently, typically aligning with new product R&D cycles or regulatory updates. Documents are generally in PDF, Word, or scanned image formats. They have complex structures, containing numerous charts, medical imaging data, and specialized terminology. Fields and units are highly specific, such as interventional device dimensions (diameter mm, length cm), material composition (polymer percentage), biocompatibility indicators (hemolysis rate %), clinical efficacy data (success rate %, complication rate %), and patient physiological parameters (blood pressure mmHg, heart rate bpm). These data require extremely high precision and consistency.
Constraints on Dialog Logging and Auditing
The complex structure and specialized nature of cardiovascular intervention R&D documents impose strict requirements on dialog logging granularity and audit rigor. Critical dimensions, materials, and clinical data within documents must be precisely captured and recorded. This ensures accurate context reproduction during dialog review. Patient safety and regulatory compliance are involved. Therefore, any reference or analysis of these data requires a clear, traceable source and reasoning process in the logs. Document updates are infrequent but impactful. This means logs need long-term storage and support precise retrieval based on version numbers or document batches. Dialogs may also involve medical image interpretation or chart data extraction, which challenges the logging system's ability to record multimodal information.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
logLevel | INFO or DEBUG | Records detailed dialog steps. This facilitates tracing data references and model decision points in complex reasoning processes. |
logRetentionDays | 1800 days | Meets long-term traceability requirements for medical device R&D, covering product lifecycle and regulatory audit periods. |
maxContext | 800–1200 characters | Ensures sufficient dialog context, including critical device parameters, clinical indicators, and regulatory clauses. |
dialogChunkSize | 500 characters | Helps record specialized terminology and data points in user questions and model responses at a fine-grained level. |
enableRawInputLogging | true | Retains raw user input completely. This aids subsequent analysis, even with specialized terminology or complex structures. |
auditTrailEnabled | true | Mandatorily enables audit records for all data access and modification operations. This meets regulatory compliance requirements. |
Common Pitfalls
- Some critical fields in dialog logs are empty, such as device model or clinical trial number. This happens because these highly specific fields were not correctly identified or extracted during document parsing.
- Historical dialog records cannot accurately reproduce Q&A results for a specific document version. This occurs because the logging system did not associate or record the knowledge base version snapshot used during the query.
- Downloading knowledge base source links results in errors or inaccessibility, showing a
404 Not Founderror. This is due to inconsistent file storage paths or incorrect permission settings in the system configuration.
Verification Steps
- From the system administration interface, select several historical dialogs at random. Check if dialog logs contain complete user questions, model responses, and referenced document snippets, especially critical data like dimensions and materials.
- Simulate a query involving sensitive data. Then, check the audit log to confirm records of the user, time, operation type, and data source accessing that data.
- Perform a knowledge base update operation, then conduct related queries. Check if dialog logs correctly associate with the updated knowledge base version. Confirm the robustness of the version iteration logging mechanism.
