Projet ECHO, Système de notation automatique pour l'E-Learning. : Étude Comportementale des Hommilières pour l'Optimisation

Abstract : An Ant Colony Optimisation technique has been implemented in order to help students visit pedagogical items proposed by Paraschool (a French leading e-learning company). The large number of students (more than 250 000) suggested to students as artificial ants, to leave stigmergic information on the web-site graph. This difference brought many changes in the original ACO process, but also a large improvement in the students' guiding system. The concept of Man-Hill has therefore been introduced.
At this stage, it becomes necessary to rate the pedagogical items to refine the model and propose the students with items corresponding to their level. The Elo rating (used in Chess competitions) is used for his purpose. As a side effect, it revealed to be also a powerful audit system that can track semantic problem in exercises.
