A navigation path planning on the Web

The main issue addressed in this paper is how to help learners navigate in existing Web-based learning resources. Our approach to this issue is to provide learners with a space, in which they can see through WWW pages to plan a navigation path in a learner-centered way.

The page previewer generates an overview of each WWW page in the map by extracting representative information from the HTML file. The path previewer helps learners make a sequence of the pages previewed as a navigation path plan. These facilities help learners decide which page to visit and plan a navigation path without visiting hyperspace
