An Auxiliary Phrase Table Approach to Closed-Loop Multi-Pass SMT

We describe a new approach to SMT based on closed loop multi-pass decoding as well as on the use of auxiliary phrase tables. In our approach, portions of an initial translation output are automatically selected, matched with their input segments, modified under specific criteria, and reintroduced to subsequent translation passes in the form of phrase tables. The motivation behind this approach is that the generation of rich morphological output (e.g., gender, person, tense) is a problem not easily resolvable within a single decoding iteration but rather, is better addressed after the output of an initial translation has been established. Our SMT experiments show consistent BLEU score improvements under several configurations in an eSupport domain translation test.
