Exploring Inductive Logic Programming to support Automatic Marking

Location: Meeting Room 10, 2nd Floor, JLB
Time: 12:30pm - 13:45pm

Automatic, online assessment is valuable for students, who can receive immediate feedback on their progress. Questions which require short responses in free text have traditionally been widely used in paper-based assessment, but it is only recently that natural language processing systems have become sufficiently robust that such questions can be used in e-assessment systems. In this talk, I will discuss the feasibility of using inductive logic programming to automate the development of mark schemes for short, free-text questions. I will compare the performance of various approaches used within the OU, and look briefly at the properties of particular questions that make them amenable (or not) to automatic marking. The talk concludes with a case study applying our system to M150 Data, Computing and Information. The system supported the Course Team chair in developing a mark scheme for the `a`student exercise.
