What it is
A practical definition
Catalog enrichment brings product data to a single shape: it aligns attributes, brands and units of measure and fills in the critical specs.
Example in ecommerce
If one product page says USB-C and another says Type-C, the system has to treat both as the same signal when it matches products.
Business impact
Raises search quality, cuts the number of extra clarifying questions and helps the assistant answer accurately on a real assortment.
