基于Web的教学超媒体中的自适应导航支持技术

用户利用WWW浏览器进行学习的最大障碍是：用户必须自行应付大量的学习材料和导航链，而有时它们是与学习目标无关的，解决问题的有效方法是自适应超媒体环境的实现，即既保持WWW特有的转称分便性，又能为用户提供导航支持，基于用户的学习历史指导下一步学习内容的选择，本文介绍基于Web的教学超媒体中的ANS技术，给出了构造领域模型和用户模型的技术方法，并着重讨论了一些简单而且有效的ANS技术。

Adaptive navigation support techniques in Web-based educational hypermedia

The WWW provides a unlimited resources of materials for learning.However,learners in the WWW face one significent problem, they have to cope with a huge amount of materials and to navigate through links which sometimes are not relevant to the learner's goal.This problem can be solved by providing learners with an adaptive hypermedia environment,which preserves most of the WWW's traditional freedom of movement through the material which providing guidance on topic selection and ,optimally,making choices on the media available to the learner based on past learning experiences.In this paper,adaptive hypermedia technique is introduced,then the domain model,user model,and adaptive navigation support techniques for web based educational hypermedia system are discussed in detail.
