The procedure for the grading of students’ essays in subject-based examinations is quite challengingudparticularly when dealing with large number of students. Hence, several automatic essay-grading systemsudhave been designed to alleviate the demands of manual subject grading. However, relatively few of theudexisting systems are able to give informative feedbacks that are based on elaborate domain knowledge toudstudents, particularly in subject-based automatic grading where domain knowledge is a major factor. In thisudwork, we discuss the vision of subject-based automatic essay scoring system that leverages on semiautomaticudcreation of subject ontology, uses ontology-based information extraction approach to enableudautomatic essay scoring, and gives informative feedback to students.
