Description:Due to limited budgets and an ever-diminishing time-frame for the production of subtitles for films released in cinemas and on DVDs, there is a compelling case for a technology-based translation solution for subtitles. The aim of this project is to develop an Example-Based Machine Translation (EBMT) system for the translation of English DVD subtitles into German and Japanese.
 To our knowledge this is the first time that any MT approach has been used with DVD subtitle translation. Due to the specific language rules imposed on the subtitler, subtitles are particularly well suited to EBMT. In addition to this, recent studies in EBMT have shown how it outperformed online rule-based MT systems as well as statistical models of rule-based Machine Translation.
 For our corpus we have acquired sets of both homogeneous and heterogeneous data from a wealth of sources including existing subtitle files, eBooks, a Translation Memory, and Speech-to-text transcripts. During testing and evaluation of our system we intend to 'plug in and out' the different sets of data, and analyse the output translation of each set. In addition to MT evaluation metrics such as BLEU and NIST, we will conduct a real-user evaluation, as this is the only reliable way of testing whether our system is working at a level, which would be suitable to produce subtitles for commercial markets, and accepted by the target audience.
