Search and recommendation data
built for buyers, not annotators.
Relevance judgment requires annotators who actually shop in your markets. We provide native-speaker evaluators in 155+ locales, product domain expertise matched to category, and quality infrastructure that has delivered at 160M+ tasks annually.
Where retail AI programs break down.
Search relevance and recommendation AI that underperforms costs revenue on every session. The failure usually traces back to the same source: relevance judgments from annotators without genuine shopping context in the target market, and recommendation training data built on English-language behavioral signals that do not generalize across cultures.
Relevance judges without market shopping context
A query result that is relevant in one market is irrelevant in another. Native-language retail context, familiarity with local product conventions, and understanding of regional shopping behavior cannot be substituted with translated guidelines. Without it, relevance judgments are systematically wrong in non-English markets.
Product catalog annotation at the wrong depth
Attribute extraction and category classification require annotators who understand regional product conventions and sizing standards. Generic annotators produce inconsistent taxonomies that degrade search ranking and recommendation precision.
Recommendation models trained on single-language behavioral data
Recommendation engines built on English-language signals fail to personalize for non-English markets where user intent, query phrasing, and product preference patterns differ at the category level.
