Data Characteristics
Registration and declaration regulation data originates from official bodies like the National Medical Products Administration (NMPA), European Medicines Agency (EMA), and U.S. Food and Drug Administration (FDA). It also includes internal Standard Operating Procedures (SOPs). These documents are commonly in PDF, Word, or HTML format. Update frequencies vary: regulations may be revised annually, while internal SOPs are updated quarterly or bi-annually based on project progress or regulatory changes. Document structures are rigorous, containing numerous clauses, appendices, charts, and cross-references. Fields and units are highly standardized, including drug names, dosage forms, specifications, indications, registration classifications, review timelines, fee units (e.g., RMB, USD, EUR), document numbers, version numbers, and effective dates.
Constraints Imposed by Data Characteristics on Workflow Orchestration
The rigor and update frequency of registration and declaration data impose specific requirements on workflow orchestration. First, the multi-source nature of official regulations and internal SOPs dictates that workflows must support fused querying across multiple knowledge bases to ensure comprehensive information coverage. Second, frequent revisions require workflows to possess version management capabilities and accurately pinpoint the latest effective version during Q&A. The extensive clauses and cross-references in documents mean that retrieval must go beyond keyword matching; it needs to understand contextual relationships. This may necessitate multi-turn conversations or complex retrieval logic to locate specific information. Furthermore, registration and declaration processes typically involve multiple stages, such as document preparation, submission, rectification, and review. Each stage has strict timelines and document requirements. Workflows must guide users accurately based on these timelines and requirements and may need to integrate external systems to query statuses, for example, to check the current review status of a registration application.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Knowledge Base Selection | Include all regulatory and internal SOP knowledge bases | Ensures Q&A covers all official and internal regulations required for registration and declaration |
Chunk Length | 800–1200 characters | Balances semantic integrity with retrieval efficiency, accommodating the length of regulatory clauses |
Similarity Threshold | 0.75 | Improves retrieval precision, reduces interference from irrelevant clauses, and ensures answer authority |
Recall Count | Top 8 | Ensures sufficient relevant context enters the context window, enhancing large model comprehension |
Rerank Return Count | Top 3 | Focuses on the most relevant regulatory clauses or SOP sections, reducing model processing burden |
Max Iterations | 3 | Handles complex multi-turn Q&A or scenarios requiring multiple retrievals of related information, such as clause cross-references |
Common Pitfalls
- The answer contains outdated or incorrect regulatory clauses due to outdated knowledge bases or chaotic version control.
- The workflow fails to correctly parse user queries about specific tables or appendices because non-text content was not effectively extracted and indexed during document preprocessing.
- HTML code output mid-process does not render correctly on the frontend because the specified reply node lacks necessary
content-typeheaders or frontend rendering logic is mismatched.
Validation Steps
- Simulate questions based on the latest regulatory revisions to verify if the workflow can accurately cite and explain the differences between old and new clauses.
- Randomly select complex questions from internal SOPs to test if the workflow can provide complete and unambiguous answers within specified time limits, comparing them against human review results.
- Input questions involving multi-departmental collaborative registration and declaration processes to check if the workflow can provide step-by-step guidance and identify required document types and responsible parties at key nodes.
- Submit queries containing specific document numbers or version numbers to verify if the workflow's returned results precisely match the content of the specified document version.
