Integrating AMR to Neural Machine Translation using Graph Attention Networks
Semantic representation is potentially useful to enforce meaning preservation and improve generalization performance of machine translation methods. In this paper, we incorporate semantic information from Abstract Meaning Representation (AMR) semantic graphs into neural machine translation. First, we use Graph Attention Networks (GATs) to encode the AMR graphs into a vector space. Then, we propose an effective way to integrate the semantic representation to the attention encoder decoder translation model. The experimental results show the improvements in BLEU scores over the baseline method on the English Vietnamese language pair.
