Reviews approaches to machine learning (development of techniques to automate acquisition of new information, skills, and ways of organizing existing information) in symbolic domains. Four categorical tasks addressed in machine learning literature are examined: learning from examples, learning search heuristics, learning by observation, and…

Discusses issues involved in offering printing for online library catalogs and weighs advantages and disadvantages of screen printing versus remote printing--speed, quality, privacy, convenience, noise, control, costs, accessibility and service. Additional technical issues discussed are buffered versus unbuffered asynchronous printer ports,…

Describes a graphic modeling, natural language processing system, VerbalImage, which mimics features of human shape reasoning. Subjects read the same text description and were able to recognize the image generated by the computer from among a series of other computer-generated images. Performance on task was as good as for a control group…

SPIRES (Stanford Public Information Retrieval System) is a computerized information storage and retrieval system intended for use by students and faculty members who have little knowledge of computers but who need rapid and sophisticated retrieval and analysis. The functions and capabilities of the system from the user's point of view are…

This progress report covers a two-year project which is part of a program that is exploring the value of computer aids in augmenting human intellectual capability. The background and nature of the program, its resources, and the activities it has undertaken are outlined. User experience in applying augmentation tools and techniques to various…

The five technical working papers that comprise the two volumes of this document are related to the problem of creating a valid process model of human communication in dialogue. In Volume 1 both papers consider reference as a phenomenon in text. The first surveys reference identification and resolution methods in various existing natural language…

The technical working papers that comprise the two volumes of this document are related to the problem of creating a valid process model of human communication in dialogue. In Volume 2, the first paper concerns study methodology, and raises such issues as the choice between system-building and process-building, and the advantages of studying cases…

This article discusses similarities between the local bulletin board system (BBS) and the public library. Highlights include components of the small BBS (system operator, host computer, "messaging" software, auto-answer device, connection to one or more phone lines); uploading and downloading; notes from the board; and the role of the…

Concepts and symbols of the language of information techology are examined, including the concept of a technological revolution, a literacy crisis, the presumption of a moral and ethical dilemma, orientation toward the future, the promise of productivity, the image of an elite using an unintelligible language, and the symbol of the infallible…

Examines capabilities of the computer as a tool for bibliographic instruction; how librarians can utilize the computers; and the effects of microcomputers on bibliographic instruction librarians. Three approaches to writing computer-assisted instruction (CAI) programs (CAI authoring system, special purpose CAI language, general purpose computer…

Outlines design requirements for situation description, policy specifications, and decision consequences feedback systems of type that could be used to help manage Research, Development, Test, and Evaluation (RDT&E) portfolios for large organizations. Several systems are described, and three additional systems design characteristics are…

The design of five experiments comparing usability evaluation methods (UEMs) is examined. Each has had an important influence on human-computer interaction (HCI); however, problems with experimental design raised questions as to the efficacy of various UEMs. To obtain desired outcomes of the experimental method addressing HCI issues, close…

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)

Planning for a computer-based personnel job opportunities system for the Air Force led to a requirement for a procedure to generate a "payoff" or "value" of the assignment of each person to each possible job. This report discusses three methods of weighting different information to form a single indicator "payoff" or "value," explicit weighting…

A translating-computer-interface approach to providing a common, or virtual-system, mode of access to a network of heterogeneous online bibliographic retrieval systems has been investigated. Enhanced access to such systems by end users has been demonstrated through test usage of an experimental interface. A table-driven, rule-based message…
