Generating Guided Tours over Indexed Information Resources
نویسندگان
چکیده
This article proposes an approach to the generation of guided tours over indexed information resources on user demand. It represents an alternative to more sophisticated hyperdocument generation techniques, in cases where very few is known about resource contents. The information space is modelled as a hypergraph of resource and resource descriptors. A spanning tree of descriptors is extracted from the line graph of this hypergraph to constitute the guided tour structure. We use a matching between spanning tree edges and a subset of transition resources to strengthen guided tour coherence and avoid redundancy. The model relies on an analysis of cognitive issues of guided tour consultation.

Generating Guided Tours to Facilitate Learning from a Set of Indexed Resources
This presentation proposes 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 descriptor...
متن کاملStudent Modeling in an Active Learning Environment using Bayesian Networks
Learning environments that allow for active (constructivist) learning lead to different adaptation requirements than environments based on more conventional teaching strategies. We discuss our approach of building adaptive hyperbooks (adaptive extendible information resources on the internet). The adaptation techniques used in our hyperbooks are based on a goal-driven approach for selecting pro...
متن کاملHyperMilano: Hypermedia Navigation in a City Information Point
This paper discusses design issues and information access paradigms in HyperMilano, a hypermedia information point about Milano. The static design of HyperMilano follows the guidelines of HDM the Hypertext Design Model which provides powerful constructs to define consistent and well organise hypermedia structures. HyperMilano supports different paradigms of information access. Free navigation a...
متن کاملUsing a Metro Map Metaphor for organizing Web-based learning resources
This paper briefly describes the WebNize system and how it applies a Metro Map metaphor for organizing guided tours in Web based resources. Then experiences in using the Metro Map based tours in a Knowledge Sharing project at the library at Aarhus School of Business (ASB) in Denmark, is discussed. The Library has been involved in establishing a Learning Resource Centre (LRC). The LRC serves as ...
متن کاملBehavioural Impacts of Mobile Tour Guides
Electronic tour guides have been developed to personalise guided tours. Also, in contrast to traditional tours, electronic tour guides allow their users to abandon or modify tours at any time. Research as to whether users take advantage of these added capabilities is currently not available. A field trial was conducted comparing the behaviour of tourists as they were using a Planner providing a...
