Data Characteristics for This Category
Quality documents in the biopharmaceutical industry typically originate from Laboratory Information Management Systems (LIMS), Electronic Batch Records (EBR), equipment calibration reports, and Standard Operating Procedures (SOPs). These documents have a relatively stable update frequency. Updates may be frequent during new drug development, while commercialized products focus more on revisions and archiving. Document structures are highly standardized, adhering to GxP requirements (e.g., GMP, GLP), and include numerous tables, figures, and specialized terminology. Fields often involve batch numbers, test items, results, deviation descriptions, auditors, and effective dates. Units strictly follow pharmacopoeia or internal standards, such as mg/mL, IU/mg, pH values, and OD600.
Constraints Imposed by These Characteristics on Deployment and Upgrade
The standardization and interconnectedness of quality documents place specific demands on FastGPT's deployment and upgrade processes. First, diverse document sources and complex formats require file parsing services, such as PDF-marker, to accurately extract table data and embedded text. This is crucial to prevent the loss of key fields due to parsing errors. Second, strict version control and audit trails are core requirements. FastGPT must seamlessly integrate with existing Document Management Systems (DMS) and support incremental knowledge base updates after document version iterations. Additionally, specialized terminology and abbreviations in documents require FastGPT's embedding models to effectively capture semantics, preventing reduced retrieval recall due to vocabulary comprehension deviations. Deployment must consider high-performance computing resources to process large volumes of mixed structured and unstructured data, ensuring query response speeds meet real-time requirements during high-pressure scenarios like inspections.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Single quality documents (including attachments, images) can be large |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Parsing complex PDFs or large table files requires sufficient time |
Chunk size (Chunk Length) | 800–1200 characters (characters) | Balances specialized terminology context and retrieval efficiency |
Recall count (Recall Count) | Top 10 entries (top 10) | Ensures comprehensive retrieval results, covering potential related information |
Similarity threshold (Similarity Threshold) | Calibrate based on actual measurements, 0.75–0.85 range suggested | Balances precision and recall, avoids irrelevant information interference |
ENABLE_GPU_INFERENCE | true | Improves embedding model processing speed and text parsing efficiency |
Three Common Pitfalls
- Symptom: FastGPT fails to recognize table data in PDF documents, or table content extraction is empty. Cause: PDF-marker version incompatibility with FastGPT, or insufficient GPU memory leading to parsing failure. Logs may show
CUDA out of memory. - Symptom: After a knowledge base update, knowledge points from some old document versions are still recalled, or new document content is not effectively indexed. Cause: The incremental synchronization mechanism between the Document Management System and FastGPT is not correctly configured, preventing FastGPT from receiving version update notifications or triggering re-indexing.
- Symptom: When querying specific batch numbers or test items, FastGPT returns irrelevant results or times out. Cause: Knowledge base indexing is not optimized for structured fields, or Nginx reverse proxy is misconfigured, preventing requests from being effectively routed to the FastGPT container, resulting in a
502 Bad Gatewayerror.
How to Verify Configuration
- Upload a PDF quality document with a complex table structure. Check if the knowledge base content preview accurately extracts table data and related text.
- Update an SOP document that already exists in the knowledge base. Observe if FastGPT triggers an incremental knowledge base update and verify that the new version content is indexed through querying.
- Use query statements containing specialized terminology and batch numbers. Verify FastGPT's response speed and result accuracy, ensuring that the recalled documents highly match the query intent.
