Data Characteristics for This Category
High-value consumable quality documentation primarily originates from manufacturer-provided registration certificates, instructions for use, technical requirements, and inspection reports. It also includes internal hospital documents such as procurement contracts, inventory records, and usage logs. Data update frequency is relatively low, typically aligning with product batch updates or regulatory changes. However, updates become rapid and mandatory during special events like recalls or adverse incidents. Document structures are often official PDF scans or electronic versions, containing extensive unstructured text and tables. Key fields include "Product Name," "Model/Specification," "Registration Certificate Number," "Production Batch Number," "Expiration Date," "Production Date," and "Sterilization Batch Number." Units involve "mm," "g," "ml," and "units (U)." Some fields exhibit ambiguity or non-standard representations.
Constraints Imposed by These Characteristics on "Deployment and Upgrade"
The unstructured PDF nature of high-value consumable documents requires FastGPT to effectively perform OCR recognition and layout analysis during data preprocessing, converting image content into indexable text. The unpredictable update frequency, especially sudden recalls or adverse events, demands high real-time synchronization and incremental update capabilities for the knowledge base. This necessitates support for rapid data import and version rollback. The presence of numerous key fields creates a high dependency on named entity recognition and information extraction capabilities to ensure retrieval accuracy. Furthermore, similar but inconsistently expressed fields across different documents increase the complexity of data cleaning and standardization, impacting the training effectiveness of vectorization models. Deployment must consider the storage space required for massive document scans and the need for elastic scaling of computing resources to handle sudden updates.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Single PDF documents (especially scanned versions) can be large; this ensures successful uploads. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | OCR recognition and complex layout parsing are time-consuming; this prevents parsing timeouts. |
Chunk size | 800–1200 characters | Balances long text context semantics and retrieval efficiency, adapting to technical document paragraph structures. |
Similarity threshold | 0.75 | Improves recall precision and reduces irrelevant information interference, suitable for quality documents requiring high accuracy. |
maxContext | 32000 tokens | Ensures the large model can process longer context information, covering complete quality clauses and descriptions. |
OCR_ENGINE_TYPE | PaddleOCR | Provides better recognition for Chinese documents and complex tables, suitable for formats like registration certificates. |
Three Common Pitfalls
- After uploading numerous PDF files, the system displays "Processing" for an extended period, eventually reporting
File parsing failedorPARSE_FILE_TIMEOUT_SECONDS. This often occurs because PDF documents contain many images, and OCR recognition takes too long, exceeding the default parsing time limit. - After importing updated documents, retrieval results still return old version information, or critical field information is missing. This happens when the incremental update strategy is misconfigured, failing to effectively cover or replace old data, or when information extraction rules do not adapt to new document field changes.
- When answering questions related to high-value consumables, the model exhibits logical errors or provides inaccurate batch information. This may manifest as
HTTP 400errors or answers lacking critical numbers or units. This can occur if indexed text segments in the vector database are too short, leading to truncation of key information and preventing the model from obtaining complete context.
How to Confirm Correct Configuration
- Upload a typical high-value consumable product instruction PDF document. Check if its parsing status shows "Success" and verify that the parsed text content is complete and free of garbled characters.
- Perform a retrieval for a specific product model and batch number. Verify if the recall results include key fields like registration certificate number, expiration date, and sterilization batch number. Confirm that field values match the original document content.
- Simulate a product recall scenario by importing an updated document containing recall information. Then, retrieve information for that product again to confirm if the model's answer accurately reflects the latest recall status and handling recommendations.
