Document extraction accuracy depends on more than choosing an OCR or AI provider. Strong results come from understanding document types, validating fields and creating a clear process for uncertain cases.
Group documents before extraction
Invoices, applications and reports require different fields and rules. Classification allows the workflow to select the correct extraction approach.
Validate against business knowledge
Check totals, identifiers, dates, allowed values and reference records. A value can be read correctly but still be invalid for the process.
Set field-level confidence rules
A document may contain some reliable fields and others that need review. Field-level thresholds prevent unnecessary rejection of the whole file.
Make review efficient
Highlight the source region and extracted value so a reviewer can correct uncertainty quickly.
Measure accuracy by document type
Overall accuracy can hide weak performance on a specific supplier, language or layout. Track results at a useful level of detail.
Choose one workflow and document its volume, current time, systems, owner and common exceptions. That information is enough to begin a useful automation assessment.
