Post-editing and machine translation quality assessment

Course title:   Post-editing and machine translation quality assessment
Course coordinator:  Professor Nataša Pavlović
Instructor: Professor Nataša Pavlović
ECTS credits:  4
Language:   English and Croatian
Semester:   summer (2nd or 4th)
Status:  Elective
Form of instruction:  2 contact hours of seminar + e-learning
Examination:  written, continuous assessment

By the end of the course the students should be able to post-edit machine translation output and assess its quality. 

The course deals with the following topics: the concept of translation quality; error classifications; post-editing vs. human translation revision; types of errors in MT output; levels of post-editing relative to translation purpose; post-editing guidelines; monolingual and bilingual post-editing; human and automatic MT quality assessment; pre-editing; integration of MT in CAT tools; MT and terminology; role of post-editing in professional translation practice; qualifications and competences required of post-editors; the impact of MT on translation theory and practice.

The coursework consists in practical tasks related to post-editing and MT quality assessment, as well as discussion of particular topics (see Week-to-week schedule). The course involves e-learning via

Regular attendance, preparedness for class, active participation in class and in e-learning, regular submission of assignments.

The final grade is based on continuous assessment of particular course elements (attendance, active participation in class and in e-learning, end-of-term paper).

After completing the course the students will be able to post-edit MT output of different types of texts in various fields in line with the guidelines and instructions; pre-edit the text for MT; assess the quality of MT output; critically assess the translation process in which MT has been used as an integral part; cooperate with other translators, terminologists and field experts; critically assess the impact of MT on translation theory and practice.
