Problems solved

  • Match records that name the same real-world thing in different words
  • Keep hard conflicts and merges in code while a model judges identity
  • Send unsure matches to a review queue instead of merging them

Use cases

  • Merchant names from card or bank statement lines
  • Duplicate customers or companies across two lists
  • Matching products across supplier catalogs
