MANY improvements for WMT’11
University of Le Mans Loic BarraultLIUM · Workshop on Statistical Machine Translation · 2011
This paper describes the development operated into MANY for the 2011 WMT system combination evaluation campaign. Hypotheses from French/English and English/French MT systems were combined with a new version of MANY, an open source system combination software based on confusion networks decoding currently developed at LIUM. MANY has been updated in order to optimize decoder parameters with MERT, which proves to find better weights. The system combination yielded significant improvements in BLEU score when applied on system combination data from two languages.
