Abstract. This paper focuses on domain specific use of MT with a special focus on SMT in the workflow of a Language Service Provider (LSP). We report on the feedback of post-editors using fluency/adequacy evaluation and the evaluation metric ’Usability’, understood in this context as where users on a three point scale evaluate the sentence from the point of view of the post-editor. The post-editor profile defined by the LSP is based on the experiences of introducing MT in the LSP workflow. The relation between the Translation Edit Rate (TER) scores and ‘Usability ’ scores is tested. We find TER a candidate for an automatic metric simulating the post-editors ’ usability judgements. LSP tests show 67 % saved time in post-editing for the tested domain. Finally, the use of weighted sub-domain phrase tables in a SMT system is shown to improve translation quality.
