Data Labeling QA Workflows

12 min read

Design multi-stage review processes to catch annotation errors before they reach your ML training pipeline.

Data Labeling QA Workflow Patterns

  • 100% Review - Every annotation reviewed by QA. Highest quality, highest cost.
  • Sample Review - Random sampling (e.g., 20% of annotations). Balances cost and quality.
  • Risk-Based Review - Review probability based on annotator experience or task difficulty.
  • Consensus Labeling - Multiple annotators label the same item. Use majority vote or expert adjudication.

Configuring QA Workflows in TigerLabel

Use the Workflow Editor to create custom multi-stage review processes with conditional routing rules based on:

  • Annotator experience level
  • Task complexity or confidence scores
  • Random sampling percentages
  • AI-flagged potential errors
