Kriya - The SFU System for Translation Task at WMT-12

摘要

This paper describes our submissions for the WMT-12 translation task using Kriya - our hierarchical phrase-based system. We submitted systems in French-English and English-Czech language pairs. In addition to the baseline system following the standard MT pipeline, we tried ensemble decoding for French-English. The ensemble decoding method improved the BLEU score by 0.4 points over the baseline in newstest-2011. For English-Czech, we segmented the Czech side of the corpora and trained two different segmented models in addition to our baseline system.
