Shallow Semantic Trees for SMT
Wilker Ferreira Aziz, Miguel Rios, Lucia Specia · 2011
We present a translation model enriched with shallow syntactic and semantic information about the source language. Base-phrase labels and semantic role labels are incorporated into an hierarchical model by creating shallow semantic “trees”. Results show an increase in performance of up to 6 % in BLEU scores for English-Spanish translation over a standard phrase-based SMT baseline. 1
