Wmt ’ 13

This paper describes LIMSI’s submissions to the shared WMT’13 translation task. We report results for French-English, German-English and Spanish-English in both directions. Our submissions use n-code, an open source system based on bilingual n-grams, and continuous space models in a post-processing step. The main novelties of this year’s participation are the following: our first participation to the Spanish-English task; experiments with source pre-ordering; a tighter integration of continuous space language models using artificial text generation (for German); and the use of different tuning sets according to the original language of the text to be translated.
