Patent ID: 8612203

Claim:
A method for statistical machine translation using a bilingual sublanguage space, said method comprising; constructing a bilingual sublanguage space by defining a similarity measure between source text and a plurality of joint count tables, each of which corresponding to one or more than one bilingual document pair, identifying a translation unit to be translated from a source language to a target language, defining a source text unit, where said source text unit comprises said translation unit, and mapping said source text unit into a weighted combination of the joint count tables, such that joint count tables corresponding to source language of the bilingual document pairs that are more similar to the source text unit are assigned greater weights, and joint count tables corresponding to source language of the bilingual document pairs that are more dissimilar from the source text unit are assigned lower weights, wherein the joint count tables are used for carrying out statistical machine translation of said translation unit according to the respective weights.
