Constructing a bayesian belief network to generate learning path in adaptive hypermedia system

In this paper, we promote an algorithm based on shortest path search algorithm to evaluate learning object (LO) based on its attributes and constructed a Bayesian Belief Network (BBN) to generate learning path for each learner. | ’ Tap ch´ Tin hoc v` Diˆu khiˆn hoc, T.24, S.1 (2008), 12–19 ı a ` e e . . . CONSTRUCTING A BAYESIAN BELIEF NETWORK TO GENERATE LEARNING PATH IN ADAPTIVE HYPERMEDIA SYSTEM NGUYEN VIET ANH, NGUYEN VIET HA, HO SI DAM College of Technology- Vietnam National University Hanoi, Vietnam; vietanh@vnu.edu.vn Abstract. There are many methods and techniques which have been promoted to develop adaptive hypermedia systems [1]. Our model approach [2], generating adaptive courses based on learner’s profile which learner’s includes background, skills, style.etc. One of important steps in our model is to generate learning path adaptive for each learner. In this paper, we promote an algorithm based on shortest path search algorithm to evaluate learning object (LO) based on its attributes [3] and constructed a Bayesian Belief Network (BBN) to generate learning path for each learner. ’ ´ ´ ’ ` e a e a e a e o ıch T´m t˘t.
