Query language determination using query terms and interface language

摘要

Methods, systems, and apparatus, including computer program products, operable to perform operations including receiving from a user through a user interface a search query comprising one or more query terms, the user interface having an interface language, the interface language being a natural language; and determining a query language for the query from the query terms and the interface language, the query language being a natural language.

1. A computer implemented method comprising:
determining, using one or more data processing apparatus, an interface language associated with a user interface through which one or more query terms of a search query are received; identifying respective languages that are associated with search result selections for a plurality of previously submitted search queries, each of the previously submitted search queries matching the search query; determining, for each identified language and based on the respective languages that are associated with the search result selections, a respective likelihood that the search query is in the language; and selecting a likelihood for a language that matches the interface language as a likelihood that one or more of the query terms are in the interface language; determining, for each of the query terms, a vector corresponding to a set of likelihoods that the respective query term is in a plurality of languages; multiplying together the vectors corresponding to the sets of likelihoods that the query terms are in the plurality of languages to generate a resultant vector; multiplying the resultant vector by the likelihood that one or more of the query terms are in the determined interface language to generate a query probability vector; and selecting a query language of the query based at least on the query probability vector.
