Syntax- and semantic-based reordering in hierarchical phrase-based statistical machine translation

作者:

Highlights:

• A syntax-based reordering model (RM) for SMT system is proposed.

• Our RM predicts the orientation between syntactic dependants of the source sentence.

• We enrich the proposed RM with semantic features, so it can perform semantic generalization.

• Our RM outperforms the baseline and two competing RMs in terms of BLEU and TER.
