Use of hypertext to provide explanations in knowledge-based systems: A conceptual model and an implementation

This paper discusses how hypertext can be used to provide explanations in knowledge-based systems (KBS), from both conceptual and implementation perspectives. To this end, it proposes a generic approach to providing hypertext-based explanations, which is based on the functional match between hypertext and explanations in KBS. A simulated KBS for financial analysis (Hyper-FINALYZER) is also described, to demonstrate the approach. First, deep knowledge can be linked to KBS output with referential links. Second, various concepts and procedures involved in problem solving can be linked to each other with both referential links and organizational links to reflect the interdependence among domain constructs and the complexity of the task domain
