Resumen:   Phrase-based statistical machine translation systems translate source sentences one phrase at a time, conditioning the choice of each phrase on very little information. Bilingual phrase table scores are computed regardless of the context in which the phrases are used and language models only look at few words surrounding the target phrases. In this thesis, we propose a novel model to predict words that should appear in a translation given the source sentence as a whole. Our model differs from previous works by its use of mlp (multilayer perceptrons). Our interest in mlp lies in their hidden layer that encodes source sentences in a representation that is only loosely tied to words. We observed that this hidden layer was able to cluster some sentences having similar translations even if they were formulated differently. In a first set of experiments, we compared favorably our mlp to ibm1, a well known model in statistical machine translation. In a second set of experiments, we embedded our ppc in our English to French statistical machine translation system. Our MLP improved translations quality over our baseline system and a second system embedding an IBM1 model. [Source: Author]
