Data Annotation / AI Data Quality
Independent Annotation Quality Control
Annotation and quality control run as separate functions: one creates labels, the other independently verifies accuracy, consistency and guideline alignment. Reviews detect missed objects, incorrect labels, boundary issues, duplicates and inconsistent decisions, supported by sampling, edge-case management and reporting.

Project overview
What we built.
A concise view of the documented implementation and features shipped.
Scope clarification: Examples are taken from the Decoding Bits Data Services portfolio. Client names and datasets are not disclosed.
- Annotation review: missing labels, wrong classes, inaccurate boxes, polygons and masks, attributes and duplicates
- Video QC: tracking IDs, drift, missing frames, movement, mask changes and temporal consistency
- Specialized QC for medical, industrial, text and audio data
- Edge-case management: unclear cases documented and final decisions recorded
- Random, percentage, range and high-risk sampling
- Rejected-task re-review and final validation
- Annotator performance, rejection patterns and quality trends
- Time-per-task and workflow bottleneck reporting
