What data looks like for this category
The data for biologics intelligent due diligence reports primarily originates from publicly available regulatory approvals from drug authorities, raw clinical trial records, production process validation documents, test reports issued by CRO institutions, and annual enterprise quality reports. Data update frequency adjusts based on regulatory requirements and project timelines. Regulatory approval updates follow quarterly or annual cycles. Clinical trial data is supplemented in real time as enrollment progresses. Document formats include official PDF approval documents, Word process descriptions, and Excel batch test data. Core fields include active ingredient identifiers, concentration units such as mg/dose, IU/mL, production batch numbers, clinical trial enrollment counts, validity period durations, and more. Structural differences vary significantly across documents from different sources.
What constraints these characteristics impose on document parsing and chunking
Biologics due diligence documents have a wide range of lengths, from a few pages of temporary approvals to hundreds of pages of multi-center trial summaries. This requires stable long-text parsing. Significant format differences exist across documents from different sources, including PDF approvals, Word process descriptions, Excel test data, and more. This requires the parsing step to support multi-format structured extraction. Professional fields use specialized units such as IU/mL, CFU/g. The binding relationship between units and corresponding values must be maintained to avoid content errors after parsing. Some documents exist as scanned images. Additional measures are needed to ensure accuracy of image-to-text conversion, to prevent loss of core test data.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Biologics due diligence reports often include hundreds of pages of clinical trial data, leading to long single-file parsing times |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Some multi-batch production process summary files have large file sizes, requiring support for large file uploads |
chunk_size | 800–1200 characters | Biologics documents contain many technical terms and long sentences. Extending chunk length appropriately preserves semantic integrity |
chunk_overlap | 100–150 characters | Prevents technical terms from being split across chunks, ensuring contextual connection between adjacent chunks |
PARSE_PDF_MARKER_ENABLE | Enabled | Accurately extract tables and structured fields from clinical trial reports, reducing parsing errors |
max_recall_chunk | Calibrated via actual testing | Adapt to context window limits of different models, preventing recalled content from exceeding model capacity |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific cases require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Issue: Core test fields are empty or have incorrect formatting after file parsing. Cause:
PARSE_PDF_MARKER_ENABLEis not enabled, so structured table content in clinical trial reports cannot be extracted correctly. - Issue: File parsing functionality fails completely when deploying a specific version of the platform locally. Cause: Dependencies for parsing tools are not configured correctly, or version compatibility issues prevent parsing modules from loading.
- Issue: JSON format errors are returned after linked online parsing. Cause: Parsed chunked JSON structures are not validated. Special units in biologics documents such as IU/mL are not properly escaped, leading to format exceptions.
How to confirm configurations are set correctly
- Upload a single clinical trial PDF document with fewer than 100 pages, check if parsed chunks retain core fields such as active ingredient concentration and production batch number.
- Upload a single summary document larger than 500 MB in size, confirm that no timeout error is triggered during parsing.
- Adjust the
chunk_sizeparameter, verify that technical terms are not split across chunks, and that reasonable overlapping content exists between adjacent chunks. - After enabling
PARSE_PDF_MARKER_ENABLE, check if table content is correctly split into independent chunks and not converted into garbled plain text.
