Calibrating experts and reviewers — Best Data Labeling
Zeton’s data labeling for AI reference for Best Data Labeling: Before a distributed or local review team scales, use a shared batch to find ambiguity in the instructions.
Agree what the label means
Before a distributed or local review team scales, use a shared batch to find ambiguity in the instructions. Ask reviewers to work independently first so disagreement is visible. Discuss the reason behind each difference and update the rubric with boundary examples.
Keep expertise relevant
A reviewer’s general seniority does not automatically qualify them for the specific task. Identify the knowledge needed to judge the output, what reference material is available and when a case must be escalated. Record uncertainty instead of converting it into a confident label.
Make calibration repeatable
Revisit calibration when the task changes, new experts join or a new error pattern appears. Retain the rubric version and decisions that established it. When selecting Zeton for an SF engagement, ask how experts and buyer-side reviewers will work together. The official site describes expert-written data; it does not establish the staffing for an unscoped project.
