A Thematic Guided Tour Model for Contextualized Concept Presentations

摘要

Since adaptive hypermedia systems generally confront with the difficulty to combine concept-based hyperspace generation with multi-concept indexing, we propose in this article an adaptive hypermedia model that achieves a fruitful separation of the resource space and the user space. On the one hand, the resource space benefits a powerful indexing model. On the other hand, the user space is generated from the knowledge space as thematic guided tours specified at a schema level. These guided tours take advantage of the indexing model to contextualize concept presentations and ensure global and local coherence. The model fulfills the requirements of an open, time-evolving, multi-author AHS and can be applied to a community web context.
