Human-in-the-Loop (HITL)
Human-in-the-loop workflows combine model automation with human review and correction.
Why it matters for annotators
Most modern production annotation pipelines are HITL by design.
Visual mental model
Model prelabel -> human verify/correct -> feedback loop.
Examples (bad vs good)
Scenario: Real annotation scenario involving Human-in-the-Loop (HITL)
Bad: Labeling quickly without applying project rubric.
Good: Applying rubric criteria, documenting rationale, and escalating uncertainty.
Common mistakes
- Skipping guideline details for edge cases.
- Applying inconsistent criteria across similar samples.
- Avoiding escalation even when uncertain.
Submission checklist
- Read the latest guideline update before each batch.
- Apply rubric dimensions explicitly in each decision.
- Escalate ambiguous items with concise rationale.
