18、 18587:2017(E)IntroductionThe use of machine translation (MT) systems to meet the needs of an increasingly demanding translation and localization industry has been gaining ground. Many translation service providers (TSPs) and clients have come to realize that the use of such systems is a viable solu

19、tion for translating projects that need to be completed within a very tight time frame and/or with a reduced budget. When an MT system is used, clients can have material translated that can otherwise not be translated; translation costs can be decreased and the launch of products on specific markets

20、, as well as the flow of information, can be accelerated. On the other hand, TSPs are able to:a) improve translation productivity;b) improve turn-around times;c) remain competitive in an environment where clients show an increasing demand for using MT in translation.However, there is no MT system wi

21、th an output which can be qualified as equal to the output of human translation and, therefore, the final quality of the translation output still depends on human translators and, for this purpose, their competence in post-editing.The rate at which MT systems are changing renders it impractical to p

22、roduce an overarching International Standard on these systems, which could stifle innovation or be ignored by the translation technology development industry.This document therefore restricts its provisions to that part of the process that begins upon the delivery of the MT output and the beginning

23、of the human process that is known as post-editing.

48、e purpose of checking its accuracy and comprehensibility, improving the text, making the text more readable, and correcting errors. Post-editing differs from translation as it involves three texts: the source text, the MT output and the final target text.There are two main levels of post-editing, li

49、ght and full; their use depends on the purpose of the translation output and the clients requirements. This document deals with full post-editing. Light post-editing is described in Annex B.The post-editing process can be automatic or human. Automatic post-editing is described in Annex E. Human post-editing refers to the MT output post-editing process performed by a human post-editor.The post-editing process can take place in an environment where all the text to be processed
