The CMU statistical machine translation system for IWSLT 2005
Abstract:
In this paper we describe the CMU statistical machine
translation system used in the IWSLT 2005 evaluation
campaign. This system is based on phrase-to-phrase
translations extracted from a bilingual corpus. We ex-
perimented with two different phrase extraction methods;
PESA on-the-fly phrase extraction and alignment free ex-
traction method. The translation model, language model
and other features were combined in a log-linear model
during decoding. We present our experiments on model
adaptation for new data in a different domain, as well as
combining different translation hypotheses to obtain bet-
ter translations.
We participated in the supplied data track for man-
ual transcriptions in the translation directions: Arabic-
English, Chinese-English, Japanese-English and Korean-
English. For Chinese-English direction we also worked
on ASR output of the supplied data, and with additional
data in unrestricted and C-STAR tracks.
