KNOWLEDGE SYSTEM WITH DISTINCT PRESENTATION AND MODEL STRUCTURE

A knowledge-based system enables one knowledge model to generate multiple presentations. A domain expert, thus, can build a hierarchical collection of “knowledge blocks” that fully characterize all aspects of a given domain. Separate presentations of the domain, targeted at different classes of users, can then be created by assembling the knowledge blocks onto web pages. If an aspect of the domain changes, the domain expert need only modify the knowledge blocks, and the presentations that use the modified knowledge blocks are thereby automatically updated. Thus, the user is insulated from the organization of the knowledge model.
