Abstract

We describe the critiquing approach to building knowledge-based interactive systems. Critiquing supports computer users in their problem solving and learning activities. The challenges for the next generation of knowledge-based systems provide a context for the development of this paradigm. We discuss critics from the perspective of overcoming the problems of high-functionality computer systems, of providing a new class of systems to support learning, of extending applications-oriented construction kits to design environments, and of providing an alternative to traditional autonomous expert systems. One of the critiquing systems we have built — JANUS, a critic for architectural design — is used as an example of the key aspects of the critiquing process. We also survey additional critiquing systems developed in our and other research groups.
