The RWTH system combination system for WMT 2009
Gregor Leusch, Evgeny Matusov, Hermann Ney · 2009
RWTH participated in the System Combination task of the Fourth Workshop on Statistical Machine Translation (WMT 2009). Hypotheses from 9 German→English MT systems were combined into a consensus translation. This consensus translation scored 2.1% better in Bleu and 2.3% better in Ter (abs.) than the best single system. In addition, cross-lingual output from 10 French, German, and Spanish→English systems was combined into a consensus translation, which gave an improvement of 2.0% in Bleu/3.5% in Ter (abs.) over the best single system.
