Ophthalmic R&D Data Characteristics
Ophthalmic R&D data comes primarily from clinical trial reports, drug submission documents, academic papers, and internal research documents. These documents update frequently, especially clinical trial data, which may have quarterly or even monthly reports. Document structures are diverse. They include structured PDF reports, Word document experiment records, and image-format medical scans. Key fields include: subject ID, disease diagnosis (e.g., glaucoma, cataracts, macular degeneration), drug name, dosage, administration route, follow-up time point, vision test results (e.g., Snellen acuity, LogMAR acuity), intraocular pressure (mmHg), visual field test results (e.g., MD value), and optical coherence tomography (OCT) parameters (e.g., central foveal retinal thickness μm). This data often contains many specialized terms and abbreviations. Units must strictly follow medical standards.
Deployment and Upgrade Constraints from Data Characteristics
The diverse structure and specialized nature of ophthalmic R&D documents impose specific requirements on FastGPT's deployment environment and upgrade strategy. First, parsing large numbers of PDF and Word documents requires significant computing resources. This is especially true when processing documents with complex tables and charts, which demand high text extraction and structuring capabilities. Embedding and retrieving medical images may require integrating additional image processing modules. Second, frequent data updates mean the knowledge base's incremental update mechanism must be efficient and stable. This avoids duplicate imports and data redundancy. The presence of many specialized terms and abbreviations requires the model to accurately understand context. This may necessitate pre-training or fine-tuning domain-specific models. Furthermore, high data security and compliance requirements make offline or intranet deployment common. This poses challenges for Docker image transfer and version management. During upgrades, new model compatibility, old data index migration, and the impact on historical query behavior all require careful planning.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1024 MB | Ophthalmic R&D documents often contain high-resolution images and detailed data, so individual files can be large. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Processing complex PDFs and image-rich Word documents can take longer, avoiding parsing timeouts. |
Chunk size | 800–1200 characters | Balances the completeness of ophthalmic professional terminology context and RAG retrieval efficiency. |
Recall count | Top 5 entries | Ensures retrieval result relevance and reduces unnecessary noise. |
Similarity threshold | 0.75 | Ensures recalled ophthalmic document segments are highly relevant to the query, filtering out general information. |
maxContext | 2000 characters | Accommodates the context length of complex ophthalmic case documents, maintaining information integrity. |
Common Pitfalls
- After local deployment, uploaded files are unreadable, but knowledge base file imports work correctly. This usually indicates an incorrect Docker container file mount path configuration. The application cannot access the host's file storage location.
- After upgrading FastGPT, some models or plugins fail to load, and the console shows a
ModuleNotFounderror. This happens because the new version adjusted dependency libraries or plugin interfaces, and old plugins are not adapted to the new environment. - Query results show inaccurate or missing explanations for ophthalmic professional terms. This may stem from the base model's insufficient understanding of ophthalmic domain knowledge, inadequate coverage of relevant professional vocabulary in the knowledge base, or the embedding model's failure to effectively capture the semantic features of specialized terms.
Verification Steps
- Upload multiple ophthalmic R&D documents in different formats (PDF, Word). Confirm the file parsing process has no errors and correctly extracts key fields and table content.
- Perform searches for professional terms like ophthalmic disease diagnoses, drug names, and vision test results. Verify that recalled document segments are highly relevant to the query intent and correctly identify and display associated units and values.
- Simulate high-concurrency document uploads and knowledge base updates. Observe system logs. Confirm no abnormal errors or performance bottlenecks. Ensure the incremental update mechanism operates stably.
- Use FastGPT's monitoring interface to check CPU, memory, disk I/O, and other resource usage. Ensure the system maintains expected performance under high load.
