Investigating usability in postediting neural machine translation: Evidence from translation trainees' self-perception and performance

Abstract This is a report on an empirical study the usability for translation trainees of neural machine systems when post-editing ( mtpe ). Sixty Chinese completed questionnaire their perceptions 's usability. Fifty them later performed both task and regular task, designed to examine by comparing performance in terms text processing speed, effort, quality. Contrasting data collected questionnaire, keylogging, eyetracking retrospective reports we found that, compared with regular, unaided translation, usefulness was remarkable: (1) it increased trainees' speed also improved quality; (2) ease use partly proved that significantly reduced informants' effort as measured (a) fixation duration counts; (b) total time; (c) number insertion keystrokes keystrokes. However, (3) generally perceived be useful increase productivity, but they were skeptical about its improve They neutral towards .
