Paper Title
Automatic Evaluation of Machine Translation: A state of Art Survey

Abstract
If the machine translation is still a scientific challenge, he applies to his evaluation. The need to judge the quality of machine translation quickly and with minimum cost, lets first have to improve the outputs of a translation system but also to compare these systems. The purpose of this paper is to present a theoretical overview about machine translation and the methods of evaluation, by presenting a number of metrics dedicate to the evaluation of machines translators. Keywords - Machine Translation; History of Machine Translation; Evaluation of Machine Translation; Metricsof Evaluation; Human Evaluation
