چکیده

We use the Margin Infused Relaxed Algorithm of Crammer et al. to add a large number of new features to two machine translation systems: the Hiero hierarchical phrasebased translation system and our syntax-based translation system. On a large-scale ChineseEnglish translation task, we obtain statistically significant improvements of +1.5 B and +1.1 B, respectively. We analyze the impact of the new features and the performance of the learning algorithm.

A new model for persian multi-part words edition based on statistical machine translation

Multi-part words in English language are hyphenated and hyphen is used to separate different parts. Persian language consists of multi-part words as well. Based on Persian morphology, half-space character is needed to separate parts of multi-part words where in many cases people incorrectly use space character instead of half-space character. This common incorrectly use of space leads to some s...

Phrasal: A Toolkit for New Directions in Statistical Machine Translation

We present a new version of Phrasal, an open-source toolkit for statistical phrasebased machine translation. This revision includes features that support emerging research trends such as (a) tuning with large feature sets, (b) tuning on large datasets like the bitext, and (c) web-based interactive machine translation. A direct comparison with Moses shows favorable results in terms of decoding s...

بهبود و توسعه یک سیستم مترجم‌یار انگلیسی به فارسی

In recent years, significant improvements have been achieved in statistical machine translation (SMT), but still even the best machine translation technology is far from replacing or even competing with human translators. Another way to increase the productivity of the translation process is computer-assisted translation (CAT) system. In a CAT system, the human translator begins to type the tra...

Improving Reordering for Statistical Machine Translation with Smoothed Priors and Syntactic Features

In this paper we propose several novel approaches to improve phrase reordering for statistical machine translation in the framework of maximum-entropy-based modeling. A smoothed prior probability is introduced to take into account the distortion effect in the priors. In addition to that we propose multiple novel distortion features based on syntactic parsing. A new metric is also introduced to ...
