Addresses the question of how to write computer programs using explicit knowledge and rules-based systems. Highlights include the knowledge representation tool; the knowledge base on programming; and results of experiments that tested the system. Appendices include the set of rules for the experimental knowledge base and details of two…

Describes expert systems and discusses their use in libraries. Highlights include parts of an expert system; expert system shells; an example of how to build an expert system; a bibliography of 34 sources of information on expert systems in libraries; and a list of 10 expert system shells used in libraries. (Contains five references.) (LRW)

Description of the use of expert systems for training applications presents three case studies of expert systems that are currently in use: (1) CESA, used for government contracting; (2) TOPSCO, for training in telecommunications; and (3) EVIDENT, for law students learning admissibility of evidence. (13 references) (LRW)

Discussion of expert systems and intelligent tutoring systems in the education field highlights an expert system that was developed to enhance the learning process in the field of grammatical constructs. Topics addressed include representing the natural language; parsing; LOGOOP (Logo in Object-Oriented Programing); and user-system interface. (11…

Describes a prototype expert system that was developed to guide the instructional design phase of instructional system development. Declarative and procedural knowledge representation methods employed in the system are explained, a sample dialog between the system and a designer is presented, and future phases of the project are discussed. (nine…

This paper describes the use of video to provide a screenplay depiction of a proposed artificial intelligence software system. Advantages of such use are identified: (1) the video can be used to provide a clear conceptualization of the proposed system; (2) it can illustrate abstract technical concepts; (3) it can simulate the functions of the…

Reviews the background, concepts, and role of hypermedia systems and analyzes essential, expected, and desirable features of hypermedia in order to provide a basis for system design and evaluation. Four hypermedium shells and systems are described, and approaches to user interface problems are discussed. (48 references) (MES)

Discusses general issues of computer and human understanding; contrasts three paradigms of information retrieval methodology, including statistical, deep semantic or natural language, and smart Boolean; describes CONIT, a knowledge-based intermediary retrieval assistance system; and examines system evaluation procedures, including a…

Summaries of research performed by the Information Sciences Institute at the University of Southern California for the U.S. Department of Defense Advanced Research Projects Agency in 17 areas are provided in this report: (1) Common LISP framework, an exportable version of the Formalized Software Development (FSD) testbed; (2) Explainable Expert…

This paper begins with a description of the context and background of cognitive research into knowledge acquisition and representation for computer based training. The nature of concept maps is alluded to and examples are given of the ways that maps can facilitate knowledge elicitation. It is noted that: (1) the concept knowledge in this research…

Describes issues and advances in the design of appropriate inference engines and knowledge structures needed by commercially feasible intelligent intermediary systems for information retrieval. Issues associated with the design of interfaces to such functions are discussed in detail. Design principles for guiding implementation of these interfaces…

This report presents a model combining the emerging technologies of hypertext and expert systems. Hypertext is relatively unexplored but promises an innovative approach to information retrieval. In contrast, expert systems have been used experimentally in many different application areas ranging from medical diagnosis to oil exploration. The…

Provides an in-depth introduction to the various technologies that are bringing intelligent agents into the forefront of information technology, explaining how such agents work, the standards involved, and how agent-based applications can be developed. (Author/AEF)

This paper is grounded in a large-scale, nine-year research project intended to design, develop, evaluate, and transfer intelligent tutoring systems (ITS) to public schools and workforce development settings. Discussion includes the implementation model; roles and responsibilities of the project team; evaluation results of the tutoring systems;…

This paper begins by examining concepts of artificial intelligence (AI) and discusses various definitions of the concept that have been suggested in the literature. The nesting relationship of expert systems within the broader framework of AI is described, and expert systems are characterized as knowledge-based systems (KBS) which attempt to solve…
