Providing Hints Based On Discovered Frequent High- Utility Patterns In A Web-Based ITS

This paper presents an exploratory data mining methodology for discovering frequent high- utility learning patterns and using them to provide hints in a web-based intelligent tutoring system (ITS). This is achieved through several phases, namely: obtaining and evaluating learning traces of each student ; transforming and encoding these traces in order to create a set of paths that led to a learning unit (“prefix” paths) and a set of paths a student took after learning a unit (“suffix” paths) ; combining the paths of all students for each learning unit into a final dataset, performing high-utility sequential pattern mining and finally storing the discovered frequent patterns in the systems database. This enables the final goal of the system – offering hints to students using our ITS. We present and discuss the results obtained by applying this methodology on interaction data from two different knowledge domains.
