Bilingually-Constrained Recursive Neural Networks with Syntactic Constraints for Hierarchical Translation Model. |
Abstract | ||
|---|---|---|
Hierarchical phrase-based translation models have advanced statistical machine translation SMT. Because such models can improve leveraging of syntactic information, two types of methods leveraging source parsing and leveraging shallow parsing are applied to introduce syntactic constraints into translation models. In this paper, we propose a bilingually-constrained recursive neural network BC-RNN model to combine the merits of these two types of methods. First we perform supervised learning on a manually parsed corpus using the standard recursive neural network RNN model. Then we employ unsupervised bilingually-constrained tuning to improve the accuracy of the standard RNN model. Leveraging the BC-RNN model, we introduce both source parsing and shallow parsing information into a hierarchical phrase-based translation model. The evaluation demonstrates that our proposed method outperforms other state-of-the-art statistical machine translation methods for National Institute of Standards and Technology 2008 NIST 2008 Chinese-English machine translation testing data. |
