Incremental Syntactic Language Models for Phrase-based Translation

Lane Schwartz, Chris Callison-Burch, William Schuler, Stephen T. Wu
2011 Annual Meeting of the Association for Computational Linguistics  
We give a formal definition of one such lineartime syntactic language model, detail its relation to phrase-based decoding, and integrate the model with the Moses phrase-based translation system.  ...  Incremental syntactic language models score sentences in a similar left-to-right fashion, and are therefore a good mechanism for incorporating syntax into phrase-based translation.  ...  syntax into phrase-based statistical machine translation, since both process sentences in an incremental left-toright fashion.  ...

Hierarchical System Combination for Machine Translation

Fei Huang, Kishore Papineni
2007 Conference on Empirical Methods in Natural Language Processing  
We propose a hierarchical system combination framework for machine translation. This framework integrates multiple MT systems' output at the word-, phrase-and sentence-levels.  ...  The full sentence translation hypotheses from multiple systems are additionally selected based on N-gram language models trained on word/word-POS mixed stream, which further improves the translation quality  ...  Acknowledgment The authors would like to thank Yaser Al-Onaizan, Abraham Ittycheriah and Salim Roukos for helpful discussions and suggestions.  ...

Bayesian Reordering Model with Feature Selection

Abdullah Alrajeh, Mahesan Niranjan
2014 Proceedings of the Ninth Workshop on Statistical Machine Translation  
In phrase-based statistical machine translation systems, variation in grammatical structures between source and target languages can cause large movements of phrases.  ...  Modeling such movements is crucial in achieving translations of long sentences that appear natural in the target language.  ...  Maximum entropy based phrase reordering model for statistical machine translation.  ...

Statistical Machine Translation with Scarce Resources Using Morpho-syntactic Information

Sonja Nießen, Hermann Ney
2004 Computational Linguistics  
Section 6 provides an overview of our procedure for training model parameters for statistical machine translation with scarce resources. Experimental results are reported in Section 7.  ...  In particular, existing statistical systems for machine translation often treat different inflected forms of the same lemma as if they were independent of one another.  ...  For the provision of the Nespole! data we thank the Nespole! consortium, listed on the project's home page (Nespole! 2000).  ...

Shallow Semantic Trees for SMT

Wilker Aziz, Miguel Rios, Lucia Specia
2011 Conference on Machine Translation  
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.  ...  For the English-German task, hierarchical models have not been shown to outperform standard phrase-based models in previous work .  ...
