This review of the book, "Conceptual Structures: Information Processing in Mind and Machine," by John F. Sowa, argues that anyone who plans to get involved with issues of knowledge representation should have at least a passing acquaintance with Sowa's conceptual graphs for a database interface. (Used to model the underlying semantics of…

Describes GeoWorks, a new graphical user interface (GUI) that works on older, less powerful IBM PCs and compatibles. The PC/GEOS (PC/Graphical Environment Operating System) is explained, user friendliness is emphasized, comparisons are made to Microsoft Windows, and GeoWorks applications software is described.

BiblioFile Intelligent Catalog is a CD-ROM-based public access catalog system which incorporates graphics and sound to provide a multisensory interface and artificial intelligence techniques to increase search precision. The system can be updated frequently and inexpensively by linking hard disk drives to CD-ROM optical drives. (MES)

Compares features of user interfaces for CD-ROM public access catalogs by six vendors: (1) Auto-Graphics; (2) Brodart; (3) General Research Corp.; (4) Library Corporation; (5) Library Systems and Services, Inc.; and (5) Marcive. Brief evaluations of the products are included, and detailed descriptions of each are appended. (MES)

Compares the strengths and weaknesses of four authoring systems that can be used for courseware development: (1) Quest; (2) PCD3; (3) IconAuthor; and (4) Course of Action. Evaluation procedures used to assess their power, ease of use, and productivity aids are explained; menu and icon structures are described; and interactive design implications…

Reviews M.B. DeBevoise's "Conversations on Mind, Matter, and Mathematics," (a book of translated conversations between Jean-Pierre Changeux and Alain Connes), which explores the question of whether a machine could reproduce the activity of the human brain. Explains how mathematics might be able to mediate between mind and matter. (DDR)

Discusses natural language retrieval systems, focusing on West Publishing Company's WIN (Westlaw Is Natural) system used with its case law database. Information retrieval models, the advantages and disadvantages of natural language retrieval, and the use of the approach by Congressional Quarterly's Washington Alert, Personal Librarian, and other…

Discussion of speech recognition technology and its use in computer-assisted instruction focuses on prototype systems designed for medical education. Commercial speech recognition systems are described, hardware and software requirements are examined, and the use of a speech recognition system to streamline an existing user interface is discussed.…

Describes an information retrieval system developed at Bell Laboratories to create and maintain a variety of different but interrelated databases, and to provide controlled access to these databases. The components discussed include the interfaces, indexing rules, display languages, response time, and updating procedures of the system. (6 notes…

This paper describes a research and development effort by Jostens Learning Corporation that resulted in the Renaissance Information Management System (RIMS), an information-management user interface for an integrated learning system that is designed to overcome two major obstacles to the use of computer systems by classroom teachers--limited…

Describes the TIS Intelligent Gateway, developed at the Lawrence Livermore National Laboratory, which uses an extensible meta-machine approach to accommodate unlimited target resources, and provides a universal user interface to simplify communications between the user and target resources. (6 references) (Author/CLB)

Compares two authoring tools that were developed to enable users without programing experience to create and modify software. HyperCard, designed for Macintosh microcomputers, and ToolBook, for microcomputers that run on MS-DOS, are compared in the areas of programing languages, graphics and printing capabilities, user interface, system…

Reviews of Compton's Multimedia Encyclopedia, New Grolier's Electronic Encyclopedia, and World Book's Information Finder are based on the 1990 editions. It is noted that all three publishers have announced plans to release annual revisions to their discs. The description of each of the products includes critiques of the search program, the…

Describes five interfaces to remote, full-text databases accessed through distributed systems of servers. These are WAIStation for the Macintosh, XWAIS for X-Windows, GWAIS for Gnu-Emacs; SWAIS for dumb terminals, and Rosebud for the Macintosh. Sixteen illustrations provide examples of display screens. Problems and needed improvements are…

Criticizes reviews of library CD-ROM products as being uncritical of the user interface and advocates a more rigorous evaluation, not only to aid potential buyers, but as a way to influence manufacturers. Congressional Information Services' Masterfile 2 is evaluated in the context of Heckel's "Principles of Friendly Software Design." (24…
