Bayesian Reordering Model with Feature Selection
Abdullah Alrajeh, Mahesan Niranjan · 2014
In phrase-based statistical machine translation systems, variation in grammatical structures between source and target languages can cause large movements of phrases.Modeling such movements is crucial in achieving translations of long sentences that appear natural in the target language.We explore generative learning approach to phrase reordering in Arabic to English.Formulating the reordering problem as a classification problem and using naive Bayes with feature selection, we achieve an improvement in the BLEU score over a lexicalized reordering model.The proposed model is compact, fast and scalable to a large corpus.
