Design a Data Labeling and Annotation Platform — System Design Interview Practice

Design a data labeling platform that supports image, text, and audio annotation, manages labeling workflows, ensures label quality, and provides active learning-based sample selection. Work through the requirements, architecture trade-offs, and an interactive design review.

Requirements and concepts to consider

  • Support image bounding box, polygon, and segmentation annotationsRequirement
  • Handle text classification, NER, and relation labelingRequirement
  • Manage labeling task assignment and workflowsRequirement
  • Implement inter-annotator agreement metricsRequirement
  • Provide pre-labeling with model-assisted suggestionsRequirement
  • Support consensus labeling and adjudicationRequirement
  • Integrate with ML training pipelinesRequirement
  • Track labeling throughput and quality metricsRequirement
