Data Characteristics
DTP pharmacy regulations and SOP data originate from regulatory documents published by drug administration authorities, drug management specifications from pharmaceutical companies, internal pharmacy operating procedures, and specific medication guidance for high-value drugs or special diseases. This data exists as PDFs, Word documents, Excel spreadsheets, or text records within internal systems. Update frequency is typically quarterly or annually, driven by policy adjustments, new drug launches, and internal management optimizations. However, some special drugs or urgent policy changes may trigger immediate updates. Document structures are rigorous, including chapters, clauses, charts, and detailed fields such as drug batch numbers, expiration dates, storage conditions, and patient education points. Units include temperature (°C), humidity (%RH), dosage (mg/kg), and frequency (times/day).
Constraints Imposed by Data Characteristics on Workflow Orchestration
The multi-source and heterogeneous nature of DTP pharmacy regulation data requires workflows with robust document parsing and integration capabilities. Workflows need to process various file formats and extract key information. The periodic updates of regulations necessitate critical version management and incremental update strategies for the knowledge base. Workflows must support automated change detection and re-indexing. Professional terminology and abbreviations in internal operating procedures pose challenges for text comprehension, requiring standardization during the preprocessing stage. Special management regulations for high-value drugs, such as cold chain transport, patient registration, and medication follow-up, mean that knowledge retrieval workflows need to combine multi-dimensional information for precise matching, for example, by integrating drug names, batch numbers, and patient medical record characteristics. The precision of fields and units requires workflows to validate information after extraction, ensuring data accuracy and preventing misinterpretation due to unit confusion.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk size (Segment Length) | 800–1200 characters | Balances the completeness of regulatory clauses with relevance during retrieval, avoiding overly fragmented or excessively long segments. |
Overlap Length | 100 characters | Ensures contextual continuity, especially for critical information spanning pages or paragraphs. |
Recall count (Retrieval Count) | top 5 | Balances query response speed with information completeness. Regulation queries often require multiple supporting pieces of information. |
Similarity threshold (Similarity Threshold) | Calibrate based on actual measurements | Ensures precision of retrieved content and avoids interference from irrelevant clauses, e.g., 0.75. |
maxContext | 32k tokens | Accommodates complex regulatory clauses and multi-condition descriptions, ensuring the model understands the complete context. |
Parsing Timeout | 600 seconds | Handles parsing of large PDF or Word files, preventing interruptions due to excessive file size. |
Common Pitfalls
- Publishing channel API access failures: Manifests as 500 errors or connection timeouts. This can be caused by a plugin or model call within the workflow taking too long, exceeding default gateway or proxy timeout limits.
- Incorrect parsing of variables in JSON input fields: Occurs when input types are not correctly declared during plugin development or when variable mapping mechanisms are not provided, leading to JSON strings being treated as literal values.
- Missing the latest policy entries in knowledge base query results: Typically due to the knowledge base update mechanism not being triggered in time, or the document parser failing to correctly identify changes in new document versions, causing the knowledge base content to be out of sync with actual regulations.
Verification Steps
- Upload the latest version of the regulation document. Check if the knowledge base index status shows "Completed" and confirm that the number of indexed documents matches the actual number of uploaded files.
- Use queries containing specific clauses or technical terms from the regulations. Verify that the retrieval results include relevant document snippets and compare the content of the snippets with the original text.
- Construct complex, multi-conditional queries, such as questions combining drug names, management processes, and exception handling. Check if the workflow correctly understands the intent and integrates multiple pieces of knowledge to provide an answer.
- Simulate concurrent user access. Monitor system resource utilization and response times to ensure the workflow remains stable under expected load and that response times meet business requirements.
