Abstract

We propose an approach to the generation of guided tours over indexed information resources on user demand. It represents a lightweight alternative to sophisticated hyperdocument generation systems based on knowledge representation and complex resource indexing. The information space is modelled as a hypergraph of resources and resource descriptors. A spanning tree of descriptors is extracted to constitute the guided tour structure. We use a matching between spanning tree edges and a set of transition resources to strengthen guided tour coherence and avoid redundancy. The model relies on an analysis of the cognitive issues of hyperdocument comprehension.
