Abstract:
1. A method of constructing a confusion set database for use in detecting user query intentions in the retrieval of sentences from a sentence database in response to the query, the method comprising: a memory coupled to a processor; obtaining a bilingual database having word pairs in first and second languages, wherein each of a plurality of word pairs in the second language in the bilingual database is aligned with a corresponding word pair in the first language in the bilingual database, the aligned word pair in the first language in the bilingual database being a correct translation word pair in the first language for the corresponding word pair in the second language; using the processor to obtain, separately from the bilingual database, human translation word pairs in the first language corresponding to each of the plurality of word pairs in the second language in the bilingual database; using the processor to align each human translation word pair in the first language with the correct translation word pair in the first language, both corresponding to the same word pair in the second language, to define first language set pairs in the confusion set database; and using the processor to remove from the confusion set database first language set pairs in which the human translation word pair in the first language and the correct translation word pair in the first language, together defining the first language set pair, are the same and wherein removing from the confusion set database first language set pairs in which the human translation word pair in the first language and the correct translation word pair in the first language are the same comprises removing both the human translation word pair in tile first language and the corresponding correct translation word pair in the first language which together define the first language set pair.
