Técnicas mejoradas para la traducción basada en frases

Nowadays, most of the statistical translation systems are based in phrases (i.e. groups of words). Here, we study different improvements to the standard phrasebased translation system. We describe a modified method for the phrase extraction which deals with larger phrases while keeping a reasonable number of phrases. We also propose additional features which lead to a clear improvement in the performance of the translation. We present results with the EuroParl task in both directions of translation between English and Spanish.
