Abstract

This paper describes the system presented for the English-Spanish translation task by the collaboration between CEU-UCH and UPV for 2011 WMT. A comparison of independent phrase-based translation models interpolation for each available training corpora were tested, giving an improvement of 0.4 BLEU points over the baseline. Output N-best lists were rescored via a target Neural Network Language Model. An improvement of one BLEU point over the baseline was obtained adding the two features, giving 31.5 BLEU and 57.9 TER for the primary system, computed over lowercased and detokenized outputs. The system was positioned second in the final ranking.
