Multifaceted quality control

When it comes to quality control, there is no silver bullet — which is why Toloka uses different
combinations of approaches to achieve the best quality for each project:

  • Crowd filters (language, interests, real-time ranking, and more)
  • Manual quality checks, spot checking
  • Task-based crowd training and testing
  • Automated quality checks (majority vote, excluding fast responses and robots, and more)
