LangDex

E-Commerce & Product Data

A seller in Shenzhen lists 'màu xanh' (Vietnamese blue). A buyer in Munich searches 'blau'. Traditional search finds nothing. Concept-based search finds both—they share PanLex concept #4521. LangDex enables cross-lingual product discovery without translating every listing.

The Challenge

The Cross-Border Discovery Problem

  • 1Product attributes are text strings: 'Cotton' in English, '棉' in Chinese, 'Coton' in French—search treats them as unrelated
  • 2Mapping seller terminology to GS1/GPC product classification requires manual curation at scale
  • 3Cross-lingual search requires pre-translating every product into every target language—O(N×M) cost
  • 4MT mistranslates technical attributes: 'stainless steel' becomes 'steel without stains' in literal translation
  • 5New products sit in localization queues for days before going live in target markets
The Solution

Concept-Based Attribute Normalization

LangDex maps product attributes to PanLex concept IDs at ingestion time. Color 'Xanh' (Vietnamese) → concept #4521 (blue). Material '綿' (Japanese cotton) → concept #7823 (cotton). At search time, query the concept, retrieve products in any source language. O(1) localization: add one concept mapping, searchable in 5,700+ languages instantly.
