e-Learning
Marking and grading ‘essay type’ questions take about a third of the time of teachers. The cost of this in economic terms is very large. This has provided the motivation for the development of an automated essay grading system. Whilst some automated essay grading systems have appeared both as commercial systems and research prototypes, they have had limited success and they mainly focus on mechanical and surface features.
Curtin Researchers has developed a set of techniques using chunking of text to capture semantic features and sophisticated data mining techniques to help model the relationship between these features and the essay grade.
