Résumé
In an intelligent tutoring system (ITS), the domain expert should provide
relevant domain knowledge to the tutor so that it will be able to guide the
learner during problem solving. However, in several domains, this knowledge is
not predetermined and should be captured or learned from expert users as well as
intermediate and novice users. Our hypothesis is that, knowledge discovery (KD)
techniques can help to build this domain intelligence in ITS. This paper proposes
a framework to capture problem-solving knowledge using a promising approach
of data and knowledge discovery based on a combination of sequential pattern
mining and association rules discovery techniques. The framework has been implemented
and is used to discover new meta knowledge and rules in a given domain
which then extend domain knowledge and serve as problem space allowing
the intelligent tutoring system to guide learners in problem-solving situations.
Preliminary experiments have been conducted using the framework as an alternative
to a path-planning problem solver in CanadarmTutor.
