As we use exactly the same modeling approach as in the syntactic method of <cite>Bastings et al. (2017)</cite> , we can easily compare the influence of the types of linguistic structures (i.e., syntax vs. semantics). We observe that when using full WMT data we obtain better results with semantics than with syntax (23.9 BLEU for syntactic GCN). Using syntactic and semantic GCN together, we obtain a further gain (24.9 BLEU) that suggests the complementarity of syntax and semantics.
