Classify a company
Read the candidates
code as a string. Store name, confidence, and the resolved domain with it so a future reviewer can understand what was classified.
Control result count
Result count is not a confidence threshold. If your workflow should accept only strong matches, filter the returned candidates by
confidence and allow an empty result after filtering.
Production behavior
- Prefer a domain over a company name when both are available.
- Do not treat a model-selected code as proof of an official registration.
- Keep the taxonomy version in your data model if records must remain auditable over time.
- Treat
404as a normal no-match and408or429as retryable with a bounded policy.
