This paper presents the experiments conducted by the Machine Translation group at DCU and Prompsit Language Engineering for the WMT13 translation task. Three language pairs are considered: SpanishEnglish and French-English in both directions and German-English in that direction. For the Spanish-English pair, the use of linguistic information to select parallel data is investigated. For the FrenchEnglish pair, the usefulness of the small indomain parallel corpus is evaluated, compared to an out-of-domain parallel data sub-sampling method. Finally, for the German-English system, we describe our work in addressing the long distance reordering problem and a system combination strategy.
