Two-Pass Based System Combination for Machine Translation
Nowadays Multiple system combination has been a hot topic in machine translation, which combines the outputs of different machine translation systems to get a better translation performance. System combination usually operates on three levels: sentence, phrase and word level. In this paper we give a new approach of system combination based on two-pass. In the first pass we generate the word alignment using the method of word level system combination. A phrase table is extracted from the word alignment. In the second pass we implement a phrase-based re-decoding similarly to phrase level system combination. In this way we can guarantee some phrases with greatest possibility of candidate translations. Furthermore we can use more features to select the final translation. We test the method on two test sets and illustrate the effectiveness of the proposed mechanism.
