Abstract
A method for resolving misspelled and phonetically variant product titles in ecommerce by applying phonetic encoding as a pre-normalization step before downstream product identity resolution. The system converts product title tokens into phonetic representations using Double Metaphone encoding, matches phonetic codes against a known-good product vocabulary, and substitutes corrected tokens before the title enters any downstream normalization or matching pipeline. This enables cross-store product resolution to handle common misspellings such as brand name variants without requiring retraining or vocabulary expansion in the downstream system.
