    A prototypical knowledge-based system that uses different identification techniques to assess the impact of new technologies is presented. Technology assessment and impact identification analysis are described in the context of environmental impact assessment (EIA), and the characteristics of ten components of EIA are discussed. A knowledge-based prototype that provides a decision framework for im... View full abstract»

    Research in equipping rule-based expert systems with skill refinement behavior by utilizing the recognize-act control mechanism is described. An overview of expert system skill refinement is provided. A skill refinement model for generating plans is then presented. Two closely coupled and mutually supportive mechanisms characterize this model: a rule-selecting mechanism (corresponding to a buyer-s... View full abstract»

    Basic expert system terminology is reviewed, and several uncertainty management paradigms are surveyed. The focus is on subjective probability theory, Dempster-Shafer theory, and possibility theory, although a number of other methods are mentioned. The benefits and limitations of the various schemes are examined, examples of expert systems within each school are presented, and some relevant open p... View full abstract»

    Extase, a situation assessment system that finds the causes of alarm signals relating to the heating furnace of a distillation column, is presented. The system is centered around two design principles. First, heterogeneous knowledge is represented by causally describing process functions. Second, a hypothesis network that supports local search control, stores time-dependent dynamic information, an... View full abstract»

    The National Library of Medicine indexes about 3000 of the world's 20000 biomedical journals and maintains various indices to health-professional literature. The decision on which journals to index is based on a policy that is difficult to apply precisely. The current method for selecting journals is described and experiments in building an expert system to facilitate that task are discussed. It i... View full abstract»

    A few issues that the author considers of central importance are identified, and their implications for the central question of how relevant current AI studies are to understanding the architecture of human intelligence are analyzed. A plausible strategy for inferring the architecture of human intelligence is outlined and used as a framework for discussing the issues raised by the author. It is co... View full abstract»
