Data Characteristics in This Category
Pharmacovigilance data in health management primarily originates from personal health records, wearable device logs, electronic medical record systems, and user-reported adverse event incidents. This data often exhibits multimodal characteristics. It includes structured patient basic information, medication records, and diagnostic results. It also contains unstructured clinical notes, free-text descriptions of symptoms from patients, and laboratory examination reports in image or PDF formats. Data update frequency is high; some physiological indicators update every minute. Medication and adverse event reports are event-driven. Document structures are complex; for example, electronic medical records often contain multiple sections, and free-text descriptions lack a unified format. Fields involved include drug names, dosages, administration routes, adverse event types, occurrence times, and severity. Units encompass international units (e.g., mg, mL) and various physiological measurement units.
Constraints Imposed by These Characteristics on "Deployment and Upgrade"
The high update frequency and multimodal nature of health management data impose constraints on FastGPT deployment regarding storage capacity and real-time processing capabilities. The large volume of unstructured text, images, and PDF documents requires robust file parsing capabilities, especially for extracting tables and text from PDF reports. Complex and varied document structures necessitate refined segmentation strategies during knowledge base construction to ensure the semantic integrity of retrieved context. Accurate identification of core fields like drug names and dosages directly impacts the quality of pharmacovigilance judgments. This requires models to adequately consider specialized biomedical vocabulary during training or fine-tuning. Additionally, due to the sensitivity of health data, the deployment environment must meet strict data security and privacy protection requirements, such as data encryption and access control. Data consistency and service continuity must be ensured during upgrades.
Configuration Strategy
| Configuration Item | Recommended Value | Rationale for Recommendation |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Accommodates large electronic medical records and examination report PDFs containing numerous images or extensive text. |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Provides sufficient time to parse large or complex PDF documents, preventing parsing timeouts. |
maxContext | 2048 characters | Ensures sufficient context related to pharmacovigilance is retrieved, including critical medication history and adverse event descriptions. |
Chunk size | 500 characters | Balances semantic completeness with retrieval efficiency, preventing irrelevant information interference from overly long segments. |
Similarity threshold | 0.75 | Improves the accuracy of relevant knowledge point retrieval in pharmacovigilance scenarios, reducing false positives. |
Rerank result count | 5 entries | Ensures the model can further filter the most relevant drug information from high-quality initial retrieval results. |
Three Common Mistakes
- A 413 error during file upload typically indicates that the
UPLOAD_FILE_MAX_SIZEconfiguration is too small. This causes the server to reject large health archives or imaging reports. - After enabling AIProxy, some external model calls function correctly, but Ollama models return empty responses. This might be due to network configuration issues in the Ollama deployment environment or problems with model loading, preventing FastGPT from establishing a proper connection or obtaining output.
- On Linux, after deploying according to the official documentation, accessing IP:3000 results in a blank, spinning browser page that fails to load the login interface. This often indicates incorrect Docker container port mapping or a firewall blocking external access to port 3000.
How to Verify the Setup
- Upload a typical PDF electronic medical record file containing multiple pages of text and a few images. Check if it parses successfully and generates knowledge base segments.
- Perform a knowledge base query for a known drug adverse event case, including keywords like drug name and symptom description. Verify if relevant medication information and vigilance knowledge are retrieved, and check the completeness of the retrieved content.
- Check the connection status of various external models (e.g., DeepSeek, Ollama) via the FastGPT administration interface. Attempt a simple conversational test to confirm that the models respond to requests normally.
