Data Characteristics in this Domain
Cardiovascular intervention R&D documents originate from clinical trial reports, device design specifications, biocompatibility assessment reports, regulatory submission files, and patent literature. Document update frequency is relatively low, typically aligning with R&D milestones or regulatory approval points. Documents have complex structures, containing extensive specialized terminology, charts, biomedical images, and multimodal data. Fields include device specifications (e.g., catheter diameter French, length cm), material composition (e.g., nickel-titanium alloy NiTi, polyurethane PU), biological effects (e.g., thrombosis rate %), and clinical indicators (e.g., restenosis rate %, stent expansion diameter mm). Units are diverse, encompassing both International System of Units (SI) and industry-specific units. Data often includes large amounts of unstructured text descriptions and tabular data.
Constraints Imposed by these Characteristics on "Deployment and Upgrade"
The complexity and multimodal nature of cardiovascular intervention R&D documents impose specific requirements on FastGPT's deployment and upgrade. Document size and specialized content necessitate higher file upload limits and longer parsing timeouts to ensure successful processing of large PDF or image files. Low update frequency but large single-update volumes require efficient bulk import mechanisms and index optimization strategies during deployment to avoid extended downtime. The specific terminology and units in documents demand good domain adaptability from the model, potentially requiring model fine-tuning or vocabulary expansion during upgrades. The presence of multimodal data means the deployment environment must support image recognition and table parsing capabilities, ensuring these components maintain good compatibility during upgrades. Furthermore, the extremely high accuracy requirements for data make the post-deployment validation phase critical, necessitating detailed validation processes.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Cardiovascular intervention R&D documents often contain high-resolution images and many pages, resulting in large file sizes. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Complex PDFs and multimodal documents can take a long time to parse, preventing parsing failures due to timeouts. |
maxContext | 800–1200 characters | Ensures sufficient document context is covered when generating responses, capturing specialized terminology and logical relationships. |
Chunk size | 400 characters | Given the specialized nature of documents, an appropriate segment length helps maintain semantic integrity and reduces information loss. |
Recall count | Top 10 entries | Increases the coverage of initial retrieval, ensuring relevant information can be captured from a large volume of specialized documents. |
Similarity threshold | Calibrated by actual measurement | Adjusts the threshold based on the semantic similarity distribution of actual document content to balance retrieval accuracy and quantity. |
Three Common Mistakes
- After deploying a new version, the client fails to deserialize the results of a specified response code execution. This typically occurs due to frontend/backend version mismatch or changes in API interface definitions.
- Official
docker-compose.ymlimage pull failures or slow speeds may be related to network environment restrictions on accessing GitHub or Docker Hub, leading to interrupted image downloads. - Slow knowledge base indexing, manifested as prolonged indexing times after importing a large number of documents, may be due to insufficient computing resources or unoptimized indexing strategies.
How to Verify Proper Configuration
- Upload a cardiovascular intervention report PDF containing complex charts and specialized terminology. Check if it parses correctly and generates a text summary.
- Ask questions targeting document snippets that include device specifications and clinical indicators. Verify FastGPT can accurately extract and answer relevant data.
- Monitor system logs to confirm no
timeoutorout of memoryerrors occur when processing large documents. - Check the knowledge base indexing status. Ensure newly imported documents are indexed quickly and are retrievable.
