Dan Melamed Computer Science Department New York University New York, NY, ... and apply a syntax-aware statisti- cal machine translation system. 1 Introduction A parser is an algorithm for inferring the structure of its input, guided by a grammar that dictates what structures ... only in the output dimension(s), then the inference is,...

... good translation candidate means the same thing as the reference translation, regardless of formulation. We propose a metric that evaluates MT output based on a rich set of features motivated by ... pairwise preferences by predicting two ab- solute scores (as before) and comparing them. 6 Data. This experiment uses the 2006–2008 cor- pora of the Workshop on Statistical Machine Trans...

... for a specific conference or to extract additional fields. 4 Translation of Scientific Texts The translation system used is a Hybrid Machine Translation (HMT) system from French to En- glish and from ... Without appropriate tools, the expertise and time spent for translation activity by the first community is lost and do not benefit to translation requests of the other communities. W...

... the 1-best accuracy and oracle accu- racy can differ by as much as an absolute 9% when the oracle is computed over a small set generated by edge-factored models (k = 50). 2 Labeled edge-factored ... chart parsing al- gorithm such as that proposed by Eisner (1996). The Eisner algorithm efficiently (O(n 3 )) generates pro- jective dependency trees by assembling structures over contiguous...

We expect do- main adaptation for machine translation can be im- proved further by combining orthogonal techniques for translation ... do- main adaptation in machine translation. 1 Introduction Statistical machine translation (SMT) systems re- quire large parallel corpora in order to be able to obtain a...

... high-quality machine transla- tions is still a long way off. A post- editing phase is required to improve the output of a machine translation system. An alternative is the so called computer- assisted translation. ... translator’s productivity. In a more ex- tended framework, a machine translation (MT) system can be used to obtain initial versions of the translations. Unfortunately...

However, here ... distribution is not affected by the order in which questions are asked. Asking about hi followed by h2 yields the same future distribution as asking about h2 followed by hi....
