Abstract : The research goal for the project reported here has been to develop enabling technology for building large knowledge bases designed to support automated and semi-automated problem solving for scientific and engineering domains. The work on analyzing problem-solving tasks, much of it preceding the project reported here, has led to the view that there are distinct, analyzable Generic Tasks (GT's) that occur naturally in problem-solving activity. The Functional Representation Language (FR), was originally introduced by Sembugamoorthy and Chandrasekaran (1986) as a device representation from which diagnosis-specific knowledge could be derived by a process of knowledge compilation. It was subsequently applied to support other tasks besides diagnosis (most notably forms of qualitative simulation), and used to represent a wide variety of device types.
