Cognitive Effort in Post-Editing of Machine Translation
Identifying indices of cognitive effort in post-editing of machine translation can serve a number of purposes, including estimating raw-output quality, calculating post-editors’ pay rates, as well as contributing to a better understanding of the activity from cognitive and psycholinguistic perspectives. I research the expenditure of cognitive effort in post-editing through a mixed-method approach involving eye tracking, a subjective scale of mental effort, and think-aloud protocols. Variables investigated in connection with effort include characteristics of the source text and machine-translation output, different linguistic aspects of the task post-editors attend to, and the fluency and adequacy of the post-edited text. From a methodological perspective, the suitability of think-aloud protocols as a method for estimating cognitive effort is also inspected, with empirical results in this respect being hoped to contribute to current methodological debates on the topic. More generally, findings obtained in the study are expected to inform professional practice as well as further Translation Studies research on the use and evaluation of machine translation.
