AAAI-97 Workshop on AI and Knowledge Management
This article describes a one-day workshop entitled AI and Knowledge Management that was held at the Fourteenth National Conference on Artificial Intelligence. The workshop was successful in identifying areas where AI techniques can be used to help those working on knowledge management and identifying areas for future work in this area.
CHEMREG: Using Case-Based Reasoning to Support Health and Safety Compliance in the Chemical Industry
CHEMREG is a large knowledge-based system used by Air Products and Chemicals, Inc., to support compliance with regulatory requirements for communicating health and safety information in the shipping and handling of chemical products. This article concentrates on one of the knowledge bases in this system: the case-based reasoner. The case-based reasoner addresses the issue of how proper communication of public health and safety information can be ensured while rapid and cost-effective product evaluation is allowed in the absence of actual hazard testing of the product. CHEMREG generates estimates of hazard data for new products from similar products using an existing relational database as a case library.
Combining Neural Networks and Context-Driven Search for Online, Printed Handwriting Recognition in the NEWTON
Yaeger, Larry S., Webb, Brandyn J., Lyon, Richard F.
We discuss a combination and improvement of classical methods to produce robust recognition of hand-printed English text for a recognizer shipping in new models of Apple Computer's NEWTON MESSAGEPAD and EMATE. Combining an artificial neural network (ANN) as a character classifier with a context-driven search over segmentation and word-recognition hypotheses provides an effective recognition system. Long-standing issues relative to training, generalization, segmentation, models of context, probabilistic formalisms, and so on, need to be resolved, however, to achieve excellent performance. We present a number of recent innovations in the application of ANNs as character classifiers for word recognition, including integrated multiple representations, normalized output error, negative training, stroke warping, frequency balancing, error emphasis, and quantized weights.
Mind: Introduction to Cognitive Science -- A Review
Bennett, Bonnie Holte, Nelson, Dwight, Pannier, Russell, Sullivan, Thomas, Robinson-Riegler, Gregory
Understanding the mind is one of the great "holy grails" of twentieth-century research. Regardless of training, most people who come in contact with the field of AI are at least partially motivated by the glimmer of hope that they will get a better understanding of the mind. This quest, of course, is a rich and complex one. It is easy to get mired in minutiae along the way, be they the optimization of an algorithm, the details of a mental model, or the intricacies of a logical argument.
CREWS_NS: Scheduling Train Crews in The Netherlands
Morgado, Ernesto M., Martins, Joao P.
We present a system, CREWS_NS, that is used in the long-term scheduling of drivers and guards for the Dutch Railways. CREWS_NS is built on top of CREWS, a scheduling tool for speeding the development of scheduling applications. CREWS heavily relies on the use of AI techniques and has been built as a white-box system, in the sense that the planner can perceive what is going on, can interact with the system by proposing alternatives or querying decisions, and can adapt the behavior of the system to changing circumstances. CREWS has mechanisms for dealing with the constant changes that occur in input data, can identify the consequences of the change, and guides the planner in accommodating the changes in the already built schedules (rescheduling).
An Intelligent System for Case Review and Risk Assessment in Social Services
The growing use of paraprofessionals as caseworkers responsible for assessment in the social services area provides fertile domain areas for new and innovative application of intelligent system technology. The main function of DISXPERT is to provide support to paraprofessional caseworkers in reaching unbiased and consistent assessment decisions regarding referral of clients to vocational rehabilitation services. The results after four years of use demonstrate that paraprofessionals using DISXPERT can make assessments in less time and with a level of accuracy superior to the vocational rehabilitation domain professionals using manual methods.
What Are Intelligence? And Why? 1996 AAAI Presidential Address
It has, for example, been interpreted in a variety of ways even within our own field, ranging from the logical view (intelligence as part of mathematical logic) to the psychological view (intelligence as an empirical phenomenon of the natural world) to a variety of others. Our physical bodies are in many ways overdetermined, unnecessarily complex, and inefficiently designed, that is, the predictable product of the blind search that is evolution. Natural intelligence is unlikely to be limited by principles of parsimony and is likely to be overdetermined, unnecessarily complex, and inefficiently designed. One example is the view that thinking is in part visual, and hence it might prove useful to develop representations and reasoning mechanisms that reason with diagrams (not just about them) and that take seriously their visual nature.
MITA: An Information-Extraction Approach to the Analysis of Free-Form Text in Life Insurance Applications
Glasgow, Barry, Mandell, Alan, Binney, Dan, Ghemri, Lila, Fisher, David
MetLife processes over 260,000 life insurance applications a year. MetLife's intelligent text analyzer (MITA) uses the information-extraction technique of natural language processing to structure the extensive textual fields on a life insurance application. MITA is currently processing 20,000 life insurance applications a month. Eighty-nine percent of the textual fields processed by MITA exceed the established confidence-level threshold and are potentially available for further analysis by domain-specific analyzers.
AI, Decision Science, and Psychological Theory in Decisions about People: A Case Study in Jury Selection
The emerging literature on combined systems is directed at domains where the prediction of human behavior is not required. Professionals concerned with human outcomes make decisions that are intuitive or analytic or some combination of both. Justifications and methodology are presented for combining analytic and intuitive agents in an expert system that supports professional decision making. The system presented demonstrates the challenges and opportunities inherent in developing and using AI-collaborative technology to solve social problems.
