Data Characteristics for This Category
Site Management Organization (SMO) quality documents primarily include Standard Operating Procedures (SOPs), work instructions, training records, quality control reports, audit reports, deviation handling records, and instrument calibration records. These documents are often stored as Word or PDF files, with some data in Excel spreadsheets. Document update frequency is high, especially with regulatory changes, new project initiations, or process optimizations. SOPs have a relatively fixed structure, typically including sections like objective, scope, responsibilities, process, and attachments. Field content involves clinical trial terminology, medical abbreviations, drug names, dosage units (e.g., mg, μg), time units (e.g., hours, days), and temperature units (e.g., ℃). Many documents are internally generated; some originate from external partners, requiring strict version control and revision history.
Constraints on Model Access and Configuration from These Characteristics
SMO quality document characteristics impose specific requirements on model access and configuration. The high update frequency necessitates efficient document synchronization and index update mechanisms for real-time retrieval. Specialized terminology and abbreviations in documents require the model to identify and process professional vocabulary during tokenization and semantic understanding, avoiding comprehension deviations from general dictionaries. The coexistence of multiple document formats demands robust document parsing capabilities, especially for accurate extraction of tables, images, and formulas from PDFs and Word files. Strict version control and revision history require effective identification and retention of version information during data chunking to prevent content confusion across versions. For fields involving specific values and units, the model must accurately match during recall. For example, when querying drug information within a specific dosage range, it should precisely distinguish between 50 mg and 500 mg.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk size (Chunk Size) | 500–800 characters | Balances document content completeness with model processing efficiency, preventing context loss. |
Overlap Size | 50–100 characters | Ensures contextual continuity at chunk boundaries, handling cross-paragraph professional terms or key information. |
Recall count (Recall Count) | 8–12 items | Covers a broader range of potentially relevant document snippets while controlling model input length. |
Similarity threshold (Similarity Threshold) | 0.75–0.85 | Improves recall accuracy for highly specialized documents requiring high semantic similarity. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Accommodates parsing time for large or complex format documents, preventing parsing failures due to timeouts. |
embeddingModel | text-embedding-ada-002 or other biomedicine-optimized models | Prioritizes embedding models with strong understanding of professional terminology, enhancing vector representation accuracy. |
Three Common Pitfalls
- Outdated or deprecated SOP content appears in query results. This occurs when the document index update mechanism fails to synchronize the latest versions in time.
- The model cannot accurately answer questions involving specific drug dosages or experimental parameters. This happens when document parsing fails to correctly extract or identify numerical values with units.
- Some professional terms or abbreviations have low matching scores during retrieval. This is because the model's tokenization and embedding model are not optimized for the biomedical domain.
How to Verify Configuration
- Select a recently revised SOP document and use question-answering tests to confirm its content updates are reflected in the model's knowledge base.
- Randomly select documents containing tabular data and professional terminology. Ask questions about relevant values and definitions, then check the model's answer accuracy.
- Use common medical abbreviations for queries to verify the model correctly understands and recalls relevant content.
- Through the FastGPT backend's knowledge base management page, check document parsing status to ensure all uploaded documents are successfully chunked and embedded.
