STATISTICAL MACHINE TRANSLATION SYSTEM AND METHOD FOR TRANSLATION OF TEXT INTO LANGUAGES WHICH PRODUCE CLOSED COMPOUND WORDS

摘要

A translation system and method for translating source text from a first language to target text in a second language are disclosed. A library of bi-phrases is accessed to retrieve bi-phrases which each match a part of the source text. Each of the bi-phrases includes respective text fragments from the first and second language. Words of some (or all) of the bi-phrases are tagged with restricted part of speech (RPOS) tags. At least one of the RPOS tags is configured for identifying a word from the second language as being one which also forms a part of a closed compound word in the library. At least one target hypothesis is generated from the bi-phrases, which includes text fragments in the second language. The target hypothesis or hypotheses are evaluated, based at least in part on combinations of the restricted part of speech tags. Based on the evaluation, one of the at least one target hypothesis is output as the optimal hypothesis for forming the translation.
