Analyze the cost-efficiency of escalating hard labels in data annotation.
Question: Explain the strategy of escalating hard labels to experts when acquiring labeled data. Why is this approach more efficient than having a full team review every example?
Sample answer: The escalation strategy involves having a junior expert label the majority of standard cases to conserve resources. Only the most difficult or ambiguous cases are escalated to more experienced experts or a full team. This is highly efficient because expert time is expensive, and it prevents wasting senior experts' time on straightforward examples that a junior expert can reliably handle.
Key points:
- A junior expert labels the vast majority of standard cases.
- Only the harder cases are escalated to more experienced experts or a team.
- The approach is driven by the high expense of senior expert time.
Rubric: The response should define the escalation strategy (junior expert handles most cases, senior experts handle difficult ones) and explain the underlying rationale (saving the expensive time of senior experts or teams).
