Abstract

In this paper we focus on the incremental decoding for a statistical phrase-based machine translation system. In incremental decoding, translations are generated incrementally for every word typed by a user, instead of waiting for the entire sentence as input. We introduce a novel modification to the beam-search decoding algorithm for phrase-based MT to address this issue, aimed at efficient computation of future costs and avoiding search errors. Our objective is to do a faster translation during incremental decoding without significant reduction in the translation quality.
