Case Study

Assign labeling work for a bird-sound dataset

Case context: A team is creating a dataset of bird-call recordings. They have one general research assistant and two highly paid expert ornithologists.

Question: How should the team divide the labeling work to keep costs under control while maintaining quality?

Sample answer: The general research assistant should label the vast majority of recordings. When a clip is especially unclear, rare, or hard to classify, those recordings should be sent to the expert ornithologists for review and final labeling.

Key points:

  • Give routine examples to the lower-cost labeler.
  • Use the first pass to identify difficult cases.
  • Reserve the experts for ambiguous or unusual recordings.

Rubric: The answer must clearly recommend that most labels come from the general assistant and that only the difficult cases be escalated to the expert ornithologists.
