Abstract

This paper, based on the first author's Ph.D. dissertation describes an experimental system for authoring and delivering tutorials on the web under the assumption that the system should deliver the latest versions of the selected documents, even when they are not controlled by the tutorial author. The great richness of materials available on the web encourages reuse of web documents in tutorials. However, the dynamic, sometimes chaotic nature of the World Wide Web poses a new challenge for tutorials that depend on links to various people's or institutions' web pages. Therefore our system includes provisions for anticipation of various kinds of changes to documents or their availability. At time of tutorial delivery, our system validates web documents by evaluating differences between document profiles stored at authoring time and new profiles based on the current versions. If appropriately constructed, the tutorials can then adapt to the changed circumstances of availability or reliability.
