Automated Evaluation of Translation Scripts in a Large-Scale Translation Contest

Abstract
Translation is a common performance task for foreign language learners. The evaluation of translation scripts, however, is not only labor-intensive and time-consuming, but also rather subjective and prone to low reliability. The study of the automated evaluation of translation is therefore of immediate practical significance.

This study draws on the state-of-the-art Doc2vec technology in NLP to construct a model for the automated evaluation of translation. The model was then used to generate a score for each of the 11,049 translation scripts collected from the Han Suyin Translation Contest. When the machine-generated scores were compared with human-generated scores, it was found that the Doc2vec-based model can produce scores with high reliability and validity. The model can efficiently identify features of good translation, and can therefore be reliably used as a second rater in large-scale translation tests.

Some of the limitations in the automated evaluation of translation are also discussed.

Key words: translation, automated evaluation, Doc2vec
