# Doc Extraction

## When to Use

- Ingesting a new standard or code (DNV-RP, API RP, ISO, ASME)
- Extracting constants, equations, or tables from technical reports
- Building structured datasets from engineering manuals
- Populating knowledge bases from document collections
- Pre-processing documents before analysis workflow
