Innovative Expert Systems with Hypertextual User Interfaces: a Special Support for the Building Recovering Project

In this paper, first of all a short account on the peculiarity of knowledge in the domain of Architectural and Building Project, particularly in the Building Recovering Project is given. Thatmeans to focus the concept of “degree of authority” of different types of knowledge with regard to project: regulations, specialist literature having in practice the value of self-regulation, technical updating, exemplary design cases, warnings, analysis methods, heuristics, orientating references. Consequently, the different roles of two basic design & decision support systems, that is expert systems and hypertexts, are considered. The former seem to be quite fit for representing information and knowledge linked to a clear “authority”, the one of experts in a certain domain, the latter seem to be quite fit for illustrating the interdisciplinary complexity, different historicinterpretations, various analogous references, and so on. Afterwards, the limits of expert systems based on the logic “true-false” are underlined, and the perspective of expert systems based on more sophisticated and appropriate rules and metarules is proposed. At last, the possible structure of such an innovative expert system, with a hypertextual interface, in the domain of Building Recovering Project is exemplified
