Statistical Post-Editing for a Statistical MT System
Hanna Béchara, Yanjun Ma, Josef van Genabith · 2011
Statistical post-editing (SPE) techniques have been successfully applied to the output of Rule Based MT (RBMT) systems. In this paper we investigate the impact of SPE on a standard Phrase-Based Statistical Machine Translation (PB-SMT) system, using PB-SMT both for the first-stage MT and the second stage SPE system. Our results show that, while a naive approach to using SPE in a PB-SMT pipeline produces no or only modest improvements, a novel combination of source context modelling and thresholding can produce statistically significant improvements of 2 BLEU points over baseline using technical translation data for French to English. 1
