Data Characteristics
Data for laboratory services primarily originates from Standard Operating Procedures (SOPs), instrument manuals, quality management system documents, safety regulations, and experimental record templates. These documents are typically in PDF, Word, or rich text formats. Some highly digitized institutions export data from Laboratory Information Management Systems (LIMS) or Electronic Lab Notebooks (ELN). Document update frequency is relatively low, usually revised annually or quarterly due to regulatory changes, technical improvements, or internal process optimizations.
Documents have a rigorous structure, containing specialized terminology, abbreviations, diagrams, and tables. Key fields include: experiment method name, number, version, revision date, scope, operating procedures, reagents and consumables, instrument parameters, quality control points, safety precautions, and emergency procedures. Units often involve metrology units like mg/L, pH, °C, rpm, with high precision requirements.
Constraints on Deployment and Upgrade
The rigorous and specialized nature of laboratory service regulation documents demands accurate text chunking during deployment. This prevents incorrect truncation of specialized terms, which could affect semantic integrity. Documents containing diagrams and tables require deployment solutions that support multimodal parsing or at least text description extraction to avoid information loss.
The low update frequency means indexing rebuild frequency can be relaxed during upgrades, but each update requires strict quality verification. Metrology units and precision requirements impose higher demands on the Q&A system for numerical reasoning and result presentation, requiring models to accurately identify and process numerical information.
The diversity of document sources requires flexible file import and preprocessing capabilities in deployment tools to adapt to different formats and data origins. Server configuration needs sufficient memory and storage capacity, as documents are often large and detailed.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Laboratory SOPs and manuals are often large; this provides ample space. |
Chunk size (Chunk Size) | 800–1200 characters | Ensures semantic integrity of specialized terms and operating procedures. |
Overlap Size | 100–200 characters | Ensures context continuity and reduces information loss. |
maxContext | 8192 | Accommodates long context requirements for complex regulation Q&A. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Addresses the time required to parse large PDF files. |
Similarity threshold (Similarity Threshold) | 0.75 | Ensures the relevance of retrieved results to professional content. |
Common Mistakes
- Symptom: System prompts "Failed to connect to Ollama" or "Model not found." Reason: When deploying locally, network connectivity issues between containers or
ollamaservice not starting correctly prevent FastGPT from connecting to the model service. - Symptom: Q&A results show significant deviations in units or numerical values, e.g.,
100 mg/Lbecomes100 g/L. Reason: Improper text chunking separates numerical values from units, or the model fails to effectively recognize and process units of measurement. - Symptom: After uploading a large SOP file, file parsing progress stalls or displays "Processing Timeout." Reason: The file parsing timeout parameter
PARSE_FILE_TIMEOUT_SECONDSis set too low, failing to accommodate the parsing time for large documents.
Verification Steps
- Upload an SOP document containing complex diagrams and specialized terminology. Check if the parsed text content is complete and free of garbled characters, paying special attention to the extraction of diagram descriptions and table data.
- Ask questions about specific operating procedures and units of measurement within the document. Verify the accuracy of the answers and check if numerical values and units match the original text.
- Simulate concurrent multi-user access. Monitor CPU, memory, and VRAM usage to ensure stable system response under high load. Adjust the
concurrencyparameter based on actual load conditions.
