Focuses on methods of generating and evaluating hypertext. Highlights include historical landmarks; nonlinearity; literary hypertext; models of hypertext; manual, automatic, and semi-automatic generation of hypertext; mathematical models for hypertext evaluation, including computing coverage and correlation; human factors in evaluation; and…

More than a third of park and recreation agencies in a 1983 survey reported use of microcomputers. This article explores types of software and hardware favored in the recreation profession. Work processing, budgeting, registration, and inventory are some of the applications used by this profession. (DF)

Presents a critique of recent theoretical developments in the field of human-computer interaction (HCI) together with an overview of HCI practice. This chapter discusses why theoretically based approaches have had little impact on the practice of interaction design and suggests mechanisms to enable designers and researchers to better articulate…

Describes the design of an experimental computer-aided cataloging advisor, Mapper, that was developed to help novice users with the descriptive cataloging of single-sheet maps from U.S. publishers. The human-computer interface is considered, the use of HyperCard is discussed, the knowledge base is explained, and assistance screens are described.…

Describes the development of a model for future national and international digital libraries. Four aspects of the model are presented: (1) nine principles underlying constructing electronic archives; (2) a study of potential user needs; (3) the design and evaluation of the user interface; and (4) objects and document type definition development.…

Discusses intelligent front-end processors designed to impose uniform standards on multiple databases and assist searchers, including motivation for development, prototypes from research community, commercial systems using microcomputers, capabilities and problems encountered in developing Franklin Institute's Online Database Search Assistance…

Introduces navigation as a central concept for information retrieval and for information systems in general. The evolution of information systems is described; navigability as an aid to improve relevance is discussed; and a system under development that attempts to facilitate navigation for information retrieval is described. (31 references) (LRW)

Discussion of human-computer interaction (HCI) as an essential part of the design of computing systems focuses on incorporating HCI into university computing courses. HCI training needs for various career profiles are given; and an outline of the contents of the Open University postgraduate module on HCI is appended. (nine references) (LRW)

Proposes a discourse analysis model of student-computer interaction, which, by viewing the student and the computer as two participants in a dialogue, provides the necessary elements and structures to describe computer-assisted language learning (CALL) discourse, analyze data from student-computer interaction, and compare CALL activities with…

Describes SHRIF, a System for Heuristic Retrieval of Information and Facts, and the medical knowledge base that was used in its development. Highlights include design decisions; the user-machine interface, including the language processor; and the organization of the knowledge base in an artificial intelligence (AI) project like this one. (57…

Identifies current trends in the automation of indexing, of information retrieval, and of interaction between the system and the users. Topics discussed include location, navigation, and indexing; digital libraries; matching documents to queries; weight of concepts; query structure, including fuzzy sets; algorithms; stemming; clustering; users'…

This paper reviews the history of separate online system interfaces which led to efforts to develop expert systems for searching databases, particularly for end users, and introduces the research on such expert systems. Appended is a bibliography of sources on interfaces and expert systems for online retrieval. (Author/EJS)

Briefly describes some experiments in human-machine interaction in the context of its relevance to multimedia audiovisual instruction, with emphasis on the use of microcomputer systems augmented with slides or audiocassettes. Fifteen references are listed. (Author/LLS)

Reviews the literature on the use of Web search engines in information science research, including: ways users interact with Web search engines; social aspects of searching; structure and dynamic nature of the Web; link analysis; other bibliometric applications; characterizing information on the Web; search engine evaluation and improvement; and…

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)
