Query translation quality confidence

A computer program product stored on a non-transitory computer readable medium which, when executed by data processing apparatus, causes the data processing apparatus to perform operations comprising:

• receiving a first visual media search query in a first language and a second visual media search query in a different second language, where the second visual media search query is determined to be a translation of the first visual media search query into the second language;
• obtaining a quality of results statistic for the second visual media search query, wherein the quality of results statistic is an estimate of expected relevance of results responsive to the second visual media search query in the second language;
• creating a final visual media search query comprising the first visual media search query in the first language, the second visual media search query in the different second language, and information corresponding to the quality of results statistic for the second visual media search query;
• and
• sending the final visual media search query to a search engine;
• and
• receiving a final group of visual media search results responsive to the final visual media search query from the search engine, wherein the final group of visual media search results comprises visual media search results satisfying a part of the final visual media search query corresponding to the first visual media search query in the first language and visual media search results satisfying a part of the final visual media search query corresponding to the second visual media search query in the second language,
• wherein each of the visual media search results in the final group is assigned a score based in part on the quality of results statistic for the second visual media search query in the second language,
• wherein each of the visual media search results in the final group is assigned with one of a plurality of confidence bins based on the quality of results statistic and wherein the visual media search results satisfying the part of the final visual media search query corresponding to the second visual media search query are assigned a score based in part on the confidence bin.

• and
• receiving a final group of visual media search results responsive to the final visual media search query from the search engine, wherein the final group of visual media search results comprises visual media search results satisfying a part of the final visual media search query corresponding to the first visual media search query in the first language and visual media search results satisfying a part of the final visual media search query corresponding to the second visual media search query in the second language,
• wherein each of the visual media search results in the final group is assigned a score based in part on the quality of results statistic for the second visual media search query in the second language,
• wherein each of the visual media search results in the final group is assigned with one of a plurality of confidence bins based on the quality of results statistic and wherein the visual media search results satisfying the part of the final visual media search query corresponding to the second visual media search query are assigned a score based in part on the confidence bin.
