Constructing a Bayesian Belief Network to Generate Learning Path in Adaptive Hypermedia System

چکیده
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.

Bayesian Modeling for Adaptive Hypermedia Systems
In this paper we show how Bayesian models can be used advantageously for various adaptation tasks in open WWW-based hypermedia systems. We discuss how to model user knowledge about different topics and learning dependencies between these topics, how to make inferences for calculating the system’s belief on a user’s knowledge based on observations from exercises/observations. We illustrate this ...

Personalized recommenders have proved to be of use as a solution to reduce the information overload problem. Especially in Adaptive Hypermedia System, a recommender is the main module that delivers suitable learning objects to learners. Recommenders suffer from the cold-start and the sparsity problems. Furthermore, obtaining learner’s preferences is cumbersome. Most studies have only focused...
متن کاملA Surface Water Evaporation Estimation Model Using Bayesian Belief Networks with an Application to the Persian Gulf
Evaporation phenomena is a effective climate component on water resources management and has special importance in agriculture. In this paper, Bayesian belief networks (BBNs) as a non-linear modeling technique provide an evaporation estimation method under uncertainty. As a case study, we estimated the surface water evaporation of the Persian Gulf and worked with a dataset of observations ...

Adaptive learning technologies have been demonstrating effective by many types of adaptive educational systems (e.g., intelligent tutoring systems, adaptive hypermedia systems, adaptive assessment systems). NMC Horizon Report 2015 predicts that this kind of learning technologies would be deployed widely in higher education in four to five years. Recently, there is a trend of shifting the measur...
