Summary
A statistical phrase-based translation model that uses hierarchical phrases — phrases that contain subphrases. The model is formally a synchronous context-free grammar but is learned from a bitext without any syntactic information. Using BLEU as a metric, the hierarchical phrase based model achieves a relative improvement of 7.5% over Pharaoh, a state-of-the-art phrase-based system.
