How Do Quality Audits Work in Data Annotation?
Quality audits involve a dedicated QA team reviewing a sample of completed annotation work to check it against the project's guidelines.
What Audits Track and Catch
- Sample review involves auditors checking a representative portion of tasks rather than every single one
- Metrics like Inter-Annotator Agreement (IAA) and individual quality scorecards are used to track each specialist's performance over time
- Error correction, where flagged data is sent back for fixes, and recurring issues feed back into training materials or the guidelines themselves
This kind of multi-tiered audit structure is what keeps quality consistent even as project volume scales up. It's a standard part of how BUNCH manages ongoing annotation work.
