The Open University ’ s repository of research publications and other research outputs Towards a learner modelling engine for the Semantic Web Conference Item

We describe XLM, the learner modelling subsystem of LEACTIVEMATH, from the viewpoint of how it makes use of technologies associated with the Semantic Web. We discuss how a better usage of these technologies could make of XLM a more generic learner modelling engine to serve a variety of elearning systems. We try to foresee important issues to be addressed and difficult problems to be solved in the way to this goal.
