Using Wordnet to Improve Reordering in Hierarchical Phrase-Based Statistical Machine Translation
Arefeh Kazemi, Antonio Toral, Andy Way · 2016
We propose the use of WordNet synsets in a syntax-based reordering model for hierarchical statistical machine translation (HPB-SMT) to enable the model to generalize to phrases not seen in the training data but that have equivalent meaning.We detail our methodology to incorporate synsets' knowledge in the reordering model and evaluate the resulting WordNetenhanced SMT systems on the English-to-Farsi language direction.The inclusion of synsets leads to the best BLEU score, outperforming the baseline (standard HPB-SMT) by 0.6 points absolute.
