Abstract

Hypertext systems and other complex information stores offer little or no guidance in helping users find information useful for activities they are currently engaged in. Most users are not interested in exploring hypertext information spaces per se but rather in obtaining information to solve problems or accomplish tasks. As a step towards this we have developed the JANUS design environment. JANUS allows designers to construct artifacts in the domain of architectural design and at the same time to be informed about principles of design and the reasoning underlying them. This process integrates two design activities: construction and argumentation. Construction is supported by a knowledge-based graphical design environment and argumentation is supported by a hypertext system. Our empirical evaluations of JANUS and its predecessors has shown that integrated support for construction and argumentation is necessary for full support of design.
