Abstract
Multilingual/cross-region search result merging is described. In various examples, a user enters a query to an information retrieval system and receives search results appropriate to different combinations of human language and geographical region, and where the combinations are selected according to features describing intent of the query. In examples, query intent features are computed using a query understanding component (e.g. a trained query intent classifier) and used, optionally with other query features, to identify combinations of human language and geographical region from a stored profile. In examples the stored profile is computed using data about documents available to an information retrieval system and data about past search behavior. In examples, different combinations of language and region are used to retrieve search results which are merged. For example, a query is translated into another language while preserving calculated intent features of the query.
