Toward Hypertext System Based Diagnosis

Artificial intelligence techniques useful in diagnosis can be classified into eight categories. Among these techniques the integrated diagnostic techniques are often presented as the most efficient to resolve practical problems. This approach may lack however some flexibility to be applied in many application domains, when the role played by users takes an important part of the diagnosis process. Hypertext systems offer now an interesting approach whenever users' interactions are important. However, to fulfil the high requirements imposed by practical and professional diagnosis, hypertext systems must satisfy constraints, which generally are not considered for common applications of hypertext. They are, for example, the ability of offering different projections of the same document; the adjunction of an instrumentation of the reading, and a well based formulated representation of involved knowledge concepts. This paper presents a preliminary study to build hypertext sy..
