UPV-PRHLT English-Spanish System for WMT10

In this paper, the system submitted by the PRHLT group for the Fifth Workshop on Statistical Machine Translation of ACL2010 is presented. On this evaluation campaign, we have worked on the English--Spanish language pair, putting special emphasis on two problems derived from the large amount of data available. The first one, how to optimize the use of the monolingual data within the language model, and the second one, how to make good use of all the bilingual data provided without making use of unnecessary computational resources.
