DETERMINING CROSS-LANGUAGE QUERY SUGGESTION BASED ON QUERY TRANSLATIONS

摘要

Computer-implemented methods, systems, computer program products for generating cross-language query suggestions are described. A pair of machine-generated translations are obtained for a primary-language query suggestion. A first machine-generated translation of the pair is generated by machine-translation from a first language to a second language, while the second machine-generated translation is generated by machine-translation from the second language to the first language. A respective difference measure is determined for each machine-generated translation based on the number of n-grams the machine-generated translation has in common with the primary-language query suggestion. The machine-generated translation that has a smaller number of n-grams in common with the primary-language query suggestion is identified as a preferred choice as a cross-language query suggestion for the primary-language query suggestion. The first language and the second language can be the preferred languages for the primary-language query suggestions and cross-language query suggestions, respectively.
