Annotator Quality Monitoring And Management

via “quality control via ground truth jobs and honeypot validation”

Open-source computer vision annotation tool.

Unique: Uses honeypot validation (mixing ground truth tasks with regular tasks) rather than explicit spot-checking, reducing annotator gaming and providing continuous quality monitoring. Quality metrics are computed automatically via annotation comparison algorithms, eliminating manual review overhead.

vs others: More systematic than Labelbox's manual review process (which requires human spot-checking) and more scalable than Prodigy's active learning approach (which requires model retraining). Honeypot approach is less intrusive than explicit quality checks, reducing annotator friction.
