Name Extraction and Translation for Distillation (2009)

Heng Ji, Ralph Grishman, Dayne Freitag, Matthias Blume, Zhiqiang (john Wang, Fair Isaac Corp, ...

Name translation is important well beyond the relative frequency of names in a text: a correctly translated passage, but with the wrong name, may lose most of its value. The Nightingale team has...

Integration of Speech to Computer-Assisted Translation Using Finite-State Automata (2009)

Shahram Khadivi, Richard Zens, Hermann Ney

State-of-the-art computer-assisted translation engines are based on a statistical prediction engine, which interactively provides completions to what a human translator types. The integration of...

Chunk-Level Reordering of Source Language Sentences with Automatically Learned Rules for Statistical Machine Translation (2008)

Yuqi Zhang, Richard Zens, Hermann Ney

In this paper, we describe a sourceside reordering method based on syntactic chunks for phrase-based statistical machine translation. First, we shallow parse the source language sentences. Then,...

A Flexible Architecture for CAT Applications (2008)

Shahram Khadivi, Richard Zens, Hermann Ney

We present an intuitive technical framework for making Computer Assisted Translation (CAT) adaptable and more suitable for rapid application development. The framework is a client-server-based...

Integrated Chinese Word Segmentation in Statistical Machine Translation (2008)

Jia Xu, Evgeny Matusov, Richard Zens, Hermann Ney

A Chinese sentence is represented as a sequence of characters, and words are not separated from each other. In statistical machine translation, the conventional approach is to segment the Chinese...

Abstract (2008)

Richard Zens, Lehrstuhl Für Informatik

This paper describes the SMT we built during the 2006 JHU Summer Workshop for the IWSLT 2006 evaluation. Our effort focuses on two parts of the speech translation problem: 1) efficient decoding of...

A Systematic Comparison of Training Criteria for Statistical Machine Translation (2008)

Richard Zens, Hermann Ney

We address the problem of training the free parameters of a statistical machine translation system. We show significant improvements over a state-of-the-art minimum error rate training baseline on a...

Phrase-based statistical machine translation : models, search, training (2008)

Zens, Richard

Die maschinelle Uebersetzung befasst sich mit dem Problem der automatischen Uebersetzung eines Textes der Quellsprache in die Zielsprache. In dieser Arbeit beschreiben nd analysieren wir den...

Moses: Open source toolkit for statistical machine translation (2007)

Hieu Hoang, Alexandra Birch, Chris Callison-burch, Richard Zens, Rwth Aachen, Alexandra Constantin, ...

We describe an open-source toolkit for statistical machine translation whose novel contributions are (a) support for linguistically motivated factors, (b) confusion network decoding, and (c)...

Minimum Bayes risk decoding for BLEU (2007)

Nicola Ehling, Richard Zens, Hermann Ney

We present a Minimum Bayes Risk (MBR) decoder for statistical machine translation. The approach aims to minimize the expected loss of translation errors with regard to the BLEU score. We show that...

Proceedings of the Workshop on Statistical Machine Translation, pages 55--63, (2006)

New York City, Richard Zens, Hermann Ney

We present discriminative reordering models for phrase-based statistical machine translation. The models are trained using the maximum entropy principle.

N -Gram Posterior Probabilities for Statistical Machine Translation (2006)

Richard Zens, Hermann Ney

Word posterior probabilities are a common approach for confidence estimation in automatic speech recognition and machine translation. We will generalize this idea and introduce n-gram posterior...

Partitioning Parallel Documents Using Binary Segmentation (2006)

Jia Xu, Richard Zens, Hermann Ney

In statistical machine translation, large numbers of parallel sentences are required to train the model parameters. However, plenty of the bilingual language resources available on web are aligned...

Statistical machine translation of european parliamentary speeches (2005)

David Vilar, Evgeny Matusov, Richard Zens, Hermann Ney

In this paper we present the ongoing work at RWTH Aachen University for building a speechto-speech translation system within the TC-Star project. The corpus we work on consists of parliamentary...

Novel reordering approaches in phrase-based statistical machine translation (2005)

Stephan Kanthak, David Vilar, Evgeny Matusov, Richard Zens, Hermann Ney

Word Graphs for Statistical Machine Translation (2005)

Richard Zens, Hermann Ney

Word graphs have various applications in the field of machine translation. Therefore it is important for machine translation systems to produce compact word graphs of high quality. We will describe...

Reordering constraints for phrase-based statistical machine translation (2004)

Richard Zens, Hermann Ney, Taro Watanabe, Eiichiro Sumita

In statistical machine translation, the generation of a translation hypothesis is computationally expensive. If arbitrary reorderings are permitted, the search problem is NP-hard. On the other hand,...

Improvements in phrase-based statistical machine translation (2004)

Richard Zens, Hermann Ney

In statistical machine translation, the currently best performing systems are based in some way on phrases or word groups. We describe the baseline phrase-based translation system and various...
