چکیده

We describe a systematic analysis on the effectiveness of features commonly exploited for the problem of predicting machine translation quality. Using a feature selection technique based on Gaussian Processes, we identify small subsets of features that perform well across many datasets for different language pairs, text domains, machine translation systems and quality labels. In addition, we show the potential of the reduced feature sets resulting from our feature selection technique to lead to significantly better performance in most datasets, as compared to the complete feature sets.

Considering the curriculum language learners are face with, one can claim that almost all language students in Iran are taught these features in their academic settings including linguistic courses. Yet, there are some aspects of language which a...

تخمین اطمینان خروجی ترجمه ماشینی با استفاده از ویژگی های جدید ساختاری و محتوایی

Despite machine translation (MT) wide suc-cess over last years, this technology is still not able to exactly translate text so that except for some language pairs in certain domains, post editing its output may take longer time than human translation. Nevertheless by having an estimation of the output quality, users can manage imperfection of this tech-nology. It means we need to estimate the c...

An Activity Theoretical Investigation into the Dominant Composition and Translation Activities of EFL learners across Persian and English

The present study aimed at investigating the impact of a genre-specific strategy-based instructional inter- vention on translation quality, dominant translation and writing activities in the persuasive essays of a group of EFL learners within the perspective of activity theory. The main purpose of the study was to see, taking translation as a sort of writing in its own right, whether the ...

An investigation of neutron direct damages at energies of 0.1-2 MeV on the DNA molecules with atomic structure deduced using Geant4 toolkit

This study proposes a method to estimate RBE of fast neutrons using Monte Carlo simulations. This approach is based on the combination of an atomic resolution DNA geometrical model and Monte Carlo simulations for tracking particles. Atomic positions were extracted from the Protein Data Bank. The GEANT4 code was used for tracking the secondary particles generated by fast neutrons during their in...

The Quality Assessment of the Persian Translation of “The Graveyard” Based on House's Translation Quality Assessment Model

The notion of Translation Quality Assessment has been the object of many studies. TQA as the compre- hensive treatment of translation evaluation, focuses on the relationship between the source text and target text and also emphasizes that translation is a linguistic operation. To accomplish this research, House‟s model of TQA was chosen as the framework for the investigation ...
