... BLEU scores both in the phrase-based model and hierarchical model as compared to the single-best segmentation approach. All results using our word-lattice decoding for the hierarchical models (hs+ss ... easily be adapted for lattice trans- lation; we achieve a unified treatment of finite-state and hierarchical phrase-based models by treating lattices as a subcase of weighted finite sta...

... implementation of a standard phrase-based decoder, so we expect that a future optimized imple- mentation of the hierarchical decoder will run at a speed competitive with other phrase-based systems. 5 ... Park, MD 20742, USA dchiang@umiacs.umd.edu Abstract We present a statistical phrase-based transla- tion model that uses hierarchical phrases— phrases that contain subphrases. The mo...

If we use phrase collocation proba- bilities as additional features, the phrase-based ... Experiments on Phrase-Based SMT 6.1 Experimental settings We use FBIS corpus to train the Chinese-to- English SMT systems. Moses (Koehn et al., 2007) is used as the baseline phrase-based...

In our tests, the best performing structure was a decision list (Rivest, 1987) of hierarchical decision trees, whose simplified basic structure is illustrated in figure 3. Note
