These stereotypes have been derived from an empirical study on a sample of adult learners at a distance learning University, while the proposed model also reflects features from several standards for a learner modeling. Finally, a web application is presented, in order to evaluate the learner model and test the automatic categorization of learners into stereotypes according to their basic characteristics. },
