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. We describe an assistant system for the navigation path planning, which is composed of a hyperspace map, page previewer and path previewer. 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.
