Data Characteristics
Bioequivalence study documents originate from internal pharmaceutical company reports. These include clinical trial reports, pharmacokinetic reports, statistical analysis reports, and regulatory submissions. Document updates are infrequent, typically occurring after a study concludes or a phase submission. Documents have complex structures, often containing numerous tables, charts, and embedded attachments like raw data files and analysis code. Key fields include drug name, active ingredient, subject information, dosing regimen, biological sample collection time points, drug concentration (Cmax, AUC0-t, AUC0-inf), statistical parameters (geometric mean ratio, 90% confidence interval), and batch information. Units include µg/mL, ng·h/mL, h, and mL, with various possible representations.
Constraints on Deployment and Upgrade
The complex structure and multiple sources of bioequivalence documents demand robust parsing, especially for data within nested tables and charts. Low update frequency means initial deployment quality is critical; subsequent iterations focus on parsing accuracy and new field identification. Diverse unit representations require a powerful unit recognition and standardization module during deployment to prevent data misinterpretation from inconsistent units. Sensitive subject information in documents necessitates data anonymization and permission management during deployment. Embedded attachments mean the deployment solution must support parsing multiple file formats and establish links between main documents and attachments.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Clinical reports are generally large, containing high-resolution charts and embedded data. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Large report parsing takes time; sufficient time is needed to prevent parsing interruptions. |
Chunk size | 800–1200 characters | Ensures integrity of key bioequivalence data paragraphs, preventing critical information from being split. |
Recall count | Top 5 entries | Bioequivalence queries typically require precise matching of a few key results; excessive recall dilutes relevance. |
Similarity threshold | Calibrate based on actual measurements | Balances precise recall and generalization for bioequivalence data characteristics. |
Entity Recognition Model | BioBERT or SciBERT | Trained specifically for biomedical texts, more accurate for drug names, concentrations, and other entities. |
Common Mistakes
- After deployment, many drug concentration values or time point fields are empty in parsing results. This occurs because the parser does not fully adapt to diverse unit representations or table structure variations in the documents.
- After local model deployment, query response speed is much lower than expected, with frequent timeouts or long waits. This is due to unoptimized concurrency parameters in inference frameworks like
vLLMfor actual hardware resources and request load. - After knowledge base creation, some PDF files cannot be imported, and the system reports file size limits. This is caused by
UPLOAD_FILE_MAX_SIZEbeing set too low, failing to accommodate the actual file size of bioequivalence study reports.
Verification
- Upload a typical bioequivalence study report. Check if key numerical fields like drug concentration, AUC values, and Cmax are complete and accurate, including correct unit recognition.
- For reports with complex tables and charts, verify that table data is correctly extracted and structured, and that chart titles and descriptions are effectively parsed.
- Use queries containing specific drug names or biomarkers. Check if the recall results include relevant documents and evaluate if the relevance of recalled items meets the expected threshold.
- In simulated high-concurrency scenarios, send continuous query requests via the API. Observe if system response times are stable and check logs for performance bottlenecks or errors.
