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.<br />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.
Ce travail de recherche se place dans le cadre de l'adaptation du paradigme de l'Optimisation par Colonie de Fourmis (OCF) à l'environnement du logiciel d'e-learning de la société Paraschool (leader français du soutien scolaire sur internet) pour le rendre intelligent et réactif à l'utilisateur. Le grand nombre d'utilisateurs a permis d'associer chaque élève à une fourmi, ce qui signifie que le mécanisme d'optimisation n'est plus basé sur une colonie de fourmis artificielles, mais sur une « colonie d'élèves » que nous appellerons Hommilière.<br /><br />Dans le but d'adapter la force des exercices aux élèves, la notation Elo des échecs a été appliquée afin d'évaluer le niveau des élèves et des items. En plus de cela, le système Elo s'avère être un très bon système d'audit, capable, entre autres, de mettre en évidence les erreurs sémantiques des exercices.
