Data labeling and preparation

Production-grade datasets with annotator agreement under control.

We collect, clean and label data for a specific task. We write annotator instructions, configure the tooling, measure agreement between annotators and re-check samples of the result. A poor dataset cannot be compensated by a good architecture, which is why we never cut this stage short.

What the work includes

  • Instructions and reference examples for annotators
  • Labeling tooling configured for the task type
  • Agreement control and sampled quality audits
  • Class balancing and handling of rare scenarios
