Translation is one of the items tested in many national English proficiency tests for non-English majors in China because translation competence is regarded as one of the productive language skills which could be used to assess learners' language proficiency. However, the feedback on translation exercises and self-tests are usually provided by human raters. As a result, students cannot have instant feedback after they finish their translation exercises or self-tests out of class, which would lead to the students' low motivation in practising translation by themselves. This paper reports on the process of the development of a dynamic online system with automated scoring and intelligent feedback for non-English majors' translation exercises and self-tests. It also discusses the obstacles encountered from a technical perspective. [For the complete volume, see ED578177.]
