Multilingual AI encoders fail to produce consistent semantic IDs across languages

By PulseAugur Editorial · [1 sources] ·

A new research paper investigates whether multilingual encoders can generate consistent semantic IDs (SIDs) across different languages for the same product. Using Amazon ESCI listings in English, Spanish, and Japanese, the study found that translations were often placed far apart in the SID space. Even with a balanced fitting mixture, cross-lingual prefix agreement decreased significantly, indicating that multilingual exposure alone does not ensure language-consistent SIDs. AI

IMPACT Highlights potential limitations in cross-lingual understanding for AI retrieval systems, impacting multilingual product search and recommendation.

    Do Multilingual Encoders Produce Language-Consistent Semantic IDs?

    Semantic IDs (SIDs) compress item embeddings into discrete code sequences used in generative retrieval. We ask whether a multilingual encoder is sufficient for different-language renderings of the same product to receive language-consistent SIDs. Using Amazon ESCI listings render…
