ABBYY Vantage Manual Review is an application where operators manually validate extracted document data, confirming that recognized information is accurate and complies with defined rules. As corrections are made, the system learns from this feedback to improve its accuracy, reducing errors and the need for manual verification in future document processing.

​
How Manual Review works

To optimize the document verification workflow, Manual Review can be organized into multiple stages handled by different users. Splitting review across stages lets each operator focus on the work that matches their expertise: less experienced operators can clear routine tasks quickly in the first stage, while documents flagged by rule violations or low-confidence extractions are escalated to more experienced reviewers in later stages. This reduces overall processing time and lowers the risk of errors slipping through unchecked. Tenant Administrators can assign the Manual Review Operator role with customized access rights, either to specific skills and stages or to all available skills and stages. Depending on their permissions, an Operator may work across the entire process or only within designated portions of it. At a high level, the manual review process follows these steps:
  1. Task Assignment
    The Manual Review Operator opens the application and receives a task containing one or more documents with automatically determined document types and extracted data.
  2. Data Verification
    The Operator checks the document type, the recognized data, and the extracted field values. When necessary, the Operator may adjust the document type, correct extracted fields, or modify field regions directly on the document image.
  3. Task Completion or Escalation
    After completing the review, the Operator finalizes the task. If additional verification is required — for example, by a more experienced reviewer — the Operator can forward the task to the next operator or stage.

How Manual Review relates to other features

Manual Review sits at the end of the document-processing pipeline, after classification and extraction have run. Several other ABBYY Vantage features shape what Operators see and do in the Client:
  • Skills define which document types are processed and which fields are extracted, establishing the data that Operators verify.
  • Rule verification determines which extractions are flagged for review — rule violations are what typically trigger escalation to a more experienced stage.
  • Data catalogs provide lookup values that populate and constrain fields during review.
  • Online Learning captures corrections made in the Client and feeds them back to improve classification and extraction accuracy over time.
If a field value is changed during manual review, the data catalog lookup rule runs again. If a matching record is found, the field becomes read-only.

Common misconceptions

Manual Review Client vs. the Manual Review activity. The Manual Review Client is the runtime application where Operators verify and correct extracted data. The Manual Review activity is the process step configured in Skill Designer that routes documents to the Client. They work together but are distinct: the activity decides when a task goes to manual review; the Client is where the operator does the work.
