One of the bases of adaptation and learning tracking is the learner’s modeling. Research in this field, or more generally in the field of user modeling, was sustained mainly on the detection of features related to the user’s knowledge, interests, goals, background, and individual traits [3]. We are interested in this last aspect, in particular the identification of the learning style. In this paper, we propose an approach for the learner’s activity perception on an e-learning platform to identify the user’s learning styles from observable indicators related to their learning path and interactions.
