    Comments obtained from interviewing dozens of women working in the artificial intelligence (AI) field are presented. The scientists discuss unbalanced percentages between genders in the AI field, experiences with stereotyping, dual-career issues, parenting, social interaction and invisibility at work, competition, and the glass ceiling of promotions. Recommendations for overcoming these obstacles ... View full abstract»

    The diagnosis system with automated rebuilding of models, or Disarm, which uses a hypothesis-and-test strategy to identify faults in chemical plants, is described. The qualitative models in Disarm describe chemical plant behavior at an abstract level, allowing diagnosis of a wide range of faults with less explicit modeling of possible faults. The model-building approach is based on the qualitative... View full abstract»

    Two models, one originating from an artificial-intelligence paradigm and the other from database research, that incorporate connectionist techniques into their knowledge representation and reasoning processes are described. The first approach, called evidential reasoning, is based on semantic networks and focuses on solving inheritance and recognition queries using a rich internal structure. The s...

  • CRACK: qualitative reasoning about fatigue and fracture in steel bridges

    Publication Year: 1992, Page(s):41 - 48

    The consultant reasoning about cracking knowledge (CRACK) system, which uses qualitative reasoning to analyze fatigue and fracture in steel bridges, is described. CRACK's architecture includes three reasoning levels-heuristic, qualitative, and quantitative-linked by a common representation of the bridge's physical structure. CRACK explains a failure by matching a crack progression sequence to the ... View full abstract»

  • The Ignatius environment: supporting the design and development of expert-system user interfaces

    Publication Year: 1992, Page(s):49 - 57

    The Ignatius user interface management system, with which designers can create user interfaces for conversational and model-based expert systems, is discussed. Because conversational and model-based expert systems require different approaches to user interface management, Ignatius consists of two separate but communicating tools: the surface interaction manager and the session discourse manager. T... View full abstract»

  • A decision-theoretic approach to planning, perception, and control

    Publication Year: 1992, Page(s):58 - 65

    The application of Bayesian decision theory as a framework for designing high-level robotic control systems is discussed. The approach to building planning and control systems integrates sensor fusion, prediction, and sequential decision making. The system explicitly uses the value of sensor information as well as the value of actions that facilitate further sensing. A stochastic decision model an... View full abstract»

    The application of an Autoclass III machine-learning algorithm for heuristic Bayesian classification to independently confirm and provide new information about structural classes of proteins is discussed. Bayesian classification and Autoclass III systems are reviewed. The decisions concerning and data representations and where to begin searching the space of potential classifications are discussed...
