AI-Based Activity Mapping
Our system standardizes company activities by mapping local classification codes to international standards through a two-step process.
Mapping Process
Step 1: Local Classifications → ISIC Rev.4
We use AI to map local activity codes to ISIC Rev.4, prioritizing precision over recall.
Priority order:
-
Local Classification Codes (Primary source)
- Country-specific codes (e.g., ATECO for Italy)
- Sector-specific codes (e.g., SIC, RAE, SAE)
- Official business register classifications
-
Activity Descriptions (Fallback source)
- Free-text activity descriptions when no local codes available
Process: AI analyzes the code and description together to find the most semantically similar ISIC code. We prefer accurate matches over complete coverage.
Step 2: ISIC Rev.4 → NACE Rev.2.1
Formal mapping from ISIC to NACE using our comprehensive mapping table.
