In short
  • Expert-annotated data is labeled or written by people with verified professional skill, such as clinicians, lawyers, engineers or accountants.
  • Demonstrations show a model step by step how an expert completes a real task, including their reasoning.
  • Professional firms can supply this as a service using staff time, without sharing any client data.
  • Buyers check credentials, guidelines and quality-control sampling before they scale an order.

Two forms of expert data

  • Annotation. Experts label existing material: classify, extract, grade or correct.
  • Demonstration. Experts complete tasks from scratch and record their reasoning, which teaches models how the work is actually done.

Why professional firms are suppliers

Specialist AI teams need far more expert time than annotation vendors can recruit. Firms with senior staff and spare capacity can supply it under a services agreement, with clear rules that no client information is used.

Quality controls buyers expect

Credential checks, written guidelines, calibration rounds, double-blind review on a sample, and agreement rates reported with every delivery.

Questions

Does this involve sharing our client files?

No. Expert data work uses the buyer's tasks or synthetic material. Client information should never be used.
