First, we introduce the concept of a learning agent shell as a tool to be used directly by a subjectmatter of theories, methods, and tools that expert (SME) to develop an agent. In his invited talk at the 1993 National strategies. In addition, it supported the (MIT), Stanford University, and Conference on Artificial Intelligence, development of methods for rapidly Northwestern University, developed two Edward Feigenbaum compared the technology extracting knowledge from natural language end-to-end integrated systems that were of a knowledge-based computer texts and the World Wide Web evaluated by Information Extraction system with a tiger in a cage. Rarely does and for knowledge acquisition from subject and Transport Inc. (IET), the challenge a technology arise that offers such a matter experts (SMEs). However, emphasis of the HPKB Program was 1999. Both systems demonstrated high this technology is still far from the use of challenge problems, which are performance through knowledge reuse achieving its potential. This tiger is in a complex, innovative military applications and semantic integration and created a cage, and to free it, the AI research community of AI that are intended to focus the significant amount of reusable knowledge.

LifeCode is a natural language processing (NLP) and expert system that extracts demographic and clinical information from free-text clinical records. The initial application of LifeCode is for the emergency medicine clinical specialty. An application for diagnostic radiology went into production in October 2000. The LifeCode NLP engine uses a large number of specialist readers whose particular output are combined at various levels to form an integrated picture of the patient's medical condition(s), course of treatment, and disposition. The LifeCode expert system performs the tasks of combining complementary information, deleting redundant information, assessing the level of medical risk and level of service represented in the clinical record, and producing an output that is appropriate for input to an electronic medical record (EMR) system or a hospital information system. Because of the critical nature of the tasks, LifeCode has a unique "self-awareness" feature that enables it to recognize the limits of its competence and, thus, ask for assistance from a human expert when faced with information that is beyond the bounds of its competence. The LifeCode NLP and expert systems reside in various delivery packages, including online transaction processing, a web browser interface, and an automated speech recognition (ASR) interface.

The SciFinance software synthesis system, licensed to major investment banks, automates programming for financial risk-management activities -- from algorithms research to production pricing to risk control. SciFinance's high-level, extensible specification language, aspen, lets quantitative analysts generate code from concise model descriptions written in application-specific and mathematical terminology; typically, a page or less produces thousands of lines of c. aspen's abstractions help analysts focus on their primary tasks -- model description, validation, and analysis -- rather than on programming details. Compared with manual programming, automation produces codes that are more sophisticated, accurate, and consistent. Analysts develop models within a day that previously took weeks or were not even attempted. SciFinance extends a system that generates scientific computing codes in a variety of target languages. The implementation integrates an object-oriented knowledge base, refinement and optimization rules, computer algebra, and a planning system. The shared knowledge base is used by the specification checker, synthesis system, and information portal.

We are interested in solving real-world planning problems and, to that end, argue for the use of domain knowledge in planning. We believe that the field must develop methods capable of using rich knowledge models to make planning tools useful for complex problems. In particular, we compare knowledge rich approaches such as hierarchical task network planning to minimal-knowledge methods such as STRIPS-based planners and disjunctive planners. Finally, we draw an analogy from the current focus of the planning community on disjunctive planners to the experiences of the machine learning community over the past decade.

We are interested in solving real-world planning problems and, to that end, argue for the use of domain knowledge in planning. We believe that the field must develop methods capable of using rich knowledge models to make planning tools useful for complex problems. We discuss the suitability of current planning paradigms for solving these problems. In particular, we compare knowledge rich approaches such as hierarchical task network planning to minimal-knowledge methods such as STRIPS-based planners and disjunctive planners. We argue that the former methods have advantages such as scalability, expressiveness, continuous plan modification during execution, and the ability to interact with humans. However, these planners also have limitations, such as requiring complete domain models and failing to model uncertainty, that often make them inadequate for real-world problems. In this article, we define the terms knowledge-based and primitive-action planning and argue for the use of knowledge-based planning as a paradigm for solving real-world problems. We next summarize some of the characteristics of real-world problems that we are interested in addressing. Several current real-world planning applications are described, focusing on the ways in which knowledge is brought to bear on the planning problem. We describe some existing knowledge-based approaches and then discuss additional capabilities, beyond those available in existing systems, that are needed. Finally, we draw an analogy from the current focus of the planning community on disjunctive planners to the experiences of the machine learning community over the past decade.

By user-driven modeling for end users and near-optimal knowledge-driven scheduling acquired from human experts, races can produce parking schedules for about 400 daily flights in approximately 20 seconds; human experts normally take 4 to 5 hours to do the same. Scheduling results in the form of Gantt charts produced by races are also accepted by the domain experts. After daily scheduling is completed, the messages for aircraft change, and delay messages are reflected and updated into the schedule according to the knowledge of the domain experts. By analyzing the knowledge model of the domain expert, the reactive scheduling steps are effectively represented as the rules, and the scenarios of the graphic user interfaces are designed.

Finally, during knowledge refinement, the models are validated through simulation on paper or with prototyping, and the knowledge bases medicine, car troubleshooting, software are refined. The last of the book's authors domain-specific knowledge, and corrections or extensions to the products has been involved in this effort since standardizing the design and development of earlier ones. Thus, the book of expert systems then became The book is intended for practitioners is particularly interesting to those who the major research problems of the in knowledge management.
