In this paper, we propose learners course recommender system of the E-Dirassa platform. This system, which distinguishes between new and active learners, adopts three complementary recommendation approaches: content-based as well course-based collaborative filtering for static profile-based learners. Let us also note use multi-criteria decision aid (MDA) techniques choice textual similarity mea...
