چکیده

We present a novel online learning approach for statistical machine translation tailored to the computer assisted translation scenario. With the introduction of a simple online feature, we are able to adapt the translation model on the fly to the corrections made by the translators. Additionally, we do online adaption of the feature weights with a large margin algorithm. Our results show that our online adaptation technique outperforms the static phrase based statistical machine translation system by 6 BLEU points absolute, and a standard incremental adaptation approach by 2 BLEU points absolute.

Optimized MT Online Learning in Computer Assisted Translation

In this paper we propose a cascading framework for optimizing online learning in machine translation for a computer assisted translation scenario. With the use of online learning, several hyperparameters associated with the learning algorithm are introduced. The number of iterations of online learning can affect the translation quality as well. We discuss these issues and propose a few approach...

Teaching approaches to Computer Assisted Language Learning

Computers have been used for language teaching ever since the 1960's.Learning a second language is a challenging endeavor, and, for decades now, proponents of computer assisted language learning (CALL) have declared that help is on the horison. We investigate the suitability of deploying speech technology in computer based systems that can be used to teach foreign language skills. In this case,...

Perceptual Learning Style Preferences and Computer-Assisted Writing Achievement within the Activity Theory Framework

Learning styles are considered among the significant factors that aid instructors in deciding how well their students learn a second or foreign language (Oxford, 2003). Although this issue has been accepted broadly in educational psychology,further research is required to examine the relationship between learning styles and language learning skills. Thus, the present study was carried out to in...

Yardsticks for Evaluating ELT Pod/Vodcasts in Online Materials Development and Their Implications for Teacher Education and Art Assisted Language Learning

ELT online materials development, which is a multifaceted multidisciplinary area, is not welcomed by many teachers, because it is demanding, challenging and confusing. They fear facing new technologies in their teaching sessions to avoid failing or being caught by other audiences. Furthermore, they struggle hard in evaluating their pod/vodcasts. In order to remove the fears and barriers, ...

Generative and Discriminative Methods for Online Adaptation in SMT

In an online learning protocol, immediate feedback about each example is used to refine the next prediction. We apply this protocol to statistical machine translation for computer-assisted translation and compare generative and discriminative approaches for online adaptation. We develop our methods on reference translations and test on feedback gathered from professional translators. Experiment...
