Data Characteristics
mRNA vaccine regulations and Standard Operating Procedures (SOPs) originate from regulatory agencies (e.g., FDA, EMA, NMPA), ICH guidelines, WHO vaccine manufacturing quality management standards, and internal quality management system documents. These documents update quarterly or annually, or irregularly for critical guidelines, depending on regulatory cycles and internal process optimizations.
Documents are primarily in PDF, Word, or structured XML/JSON formats. They cover the entire lifecycle from R&D, clinical trials, production, quality control, transportation, to post-market surveillance. Fields and units are highly specialized. For example, "stability data" includes "temperature (Celsius)," "relative humidity (%)", and "storage time (months)." "Purity testing" involves "RNA integrity (%)" and "lipid nanoparticle size (nanometers)."
Constraints Imposed by Data Characteristics on HTTP Interface and External Systems
The specialized nature and diverse structure of mRNA vaccine regulatory data impose specific requirements on HTTP interface data parsing. PDF regulatory documents, for instance, require robust OCR and natural language processing to extract key information. Structured data needs precise mapping to FastGPT knowledge base fields.
Irregular regulatory updates mean the interface must support incremental synchronization and version management to ensure knowledge base timeliness. Specialized units and data types, such as the numerical range for nanoparticle size, demand strict validation during data import to prevent semantic errors from unit or type mismatches.
SOPs involving sensitive production processes and quality control require higher standards for data transmission security, encryption protocols, and access permission management. This ensures information integrity and confidentiality during transmission and storage.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 6000 characters | mRNA vaccine regulatory documents are generally lengthy, requiring a larger context window to maintain complete context. |
Chunk size (Segment Length) | 800–1200 characters | Balances semantic completeness and retrieval efficiency. Avoids context loss from overly short segments and noise from overly long ones. |
Similarity threshold (Similarity Threshold) | 0.75 | Regulatory Q&A demands high accuracy. A higher threshold effectively filters out irrelevant or ambiguous recall results. |
Rerank result count (Reranked Return Count) | 5 entries | Ensures comprehensive recall results while avoiding excessive redundant information that could affect final answer generation. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Parsing large PDF or Word documents can be time-consuming, requiring a longer timeout to prevent interruptions. |
UPLOAD_FILE_MAX_SIZE | 500 MB | Supports uploading regulatory documents containing numerous charts and attachments, ensuring file uploads are not limited by size. |
Common Pitfalls
- After importing data from an external system, some field content appears empty or garbled. This happens due to incorrect character encoding configuration or data type mapping mismatches.
- After a knowledge base update, the model still answers based on the old version of regulations. This occurs because the external system did not trigger incremental synchronization, or webhook configuration errors prevented update notifications from being delivered.
- Frequent HTTP interface calls result in connection timeout errors. This indicates that concurrent requests exceed the capacity of the external system or FastGPT server, and appropriate rate limiting or load balancing has not been configured.
Verification of Configuration
- Upload mRNA vaccine regulatory documents in various formats (PDF, Word, JSON) via the HTTP interface. Check the completeness and accuracy of the content in the knowledge base, especially professional terminology and numerical fields.
- Simulate an external system publishing a regulatory update. Observe whether the knowledge base synchronizes the latest content promptly and verify if the model can reference the updated information when queried.
- Use FastGPT's API debugging tool to ask questions containing specialized terms and specific values. Check if the returned results accurately cite clauses from the knowledge base and verify the professionalism and consistency of the answers.
- In the system logs, check
HTTP status codesanderror messagesto ensure no parsing failures, connection timeouts, or permission errors are reported.
