Describes the mouse and other pointing devices used with microcomputers to facilitate easier user-microcomputer interaction, reviews previous educational applications and research, presents a study comparing the efficiency of the mouse with users of different ages, and discusses the implications for software design. (MBR)

A number of projects over the past decade, in a range of educational contexts, have sought to link forms and patterns of communicative interaction to improvements in knowledge, conceptual understanding and reasoning skills. These initiatives have produced dialog models, methodologies for developing these in ways that lead to the design of…

This paper describes an evaluation of the Kea automatic keyphrase extraction algorithm. Tools that automatically identify keyphrases are desirable because document keyphrases have numerous applications in digital library systems, but are costly and time consuming to manually assign. Keyphrase extraction algorithms are usually evaluated by…

A classification system for analyzing the dynamics of energy consumption in building components. (Author/MF)

Describes a two-phase stemming algorithm which consists of word root identification and automatic selection of word variants starting with same word root from inverted file. Use of algorithm in book catalog file is discussed. Ten references and example of subject search are appended. (EJS)

Describes a microcomputer software system designed at British Library which will interface with existing BLAISE services; e.g., offline editing of records retrieved online, stored search, and data preparation facilities. A technical description, features of system, applications programs, and the CORTEX interface with the mainframe system are…

Describes a computer-aided instruction program developed at Sheffield City Polytechnic, England, which teaches students to analyze simple sentences into their constituents and to draw tree diagrams representing their structures. Program strategy, control and operation of the programs, and evaluation are discussed. Three references and illustrative…

Describes the computing environment and command language for a new programing language called OUSBASIC which is designed to enable naive users to interact usefully, with little assistance, with a computer system. (Author/CHC)

Discusses why computer assisted instruction did not work in many classrooms, how older people have fought the new technology, and why implementation of computer technology as part of training has been slow. Also examines uses of the videodisc and microcomputer and the trainer's role. (CT)

Proposes a problem-oriented, man-machine modelling process which combines algorithms and software to assist decision makers and planners in dealing with complex socio-economic issues. Includes the specific parts in each of the system's three basic elements: a library, special units, and system control units. (Author/DC)

Discusses and compares some online catalog systems actually in operation in terms of self-service usability; number, choice, and formulation of access points; record content and display; database content; connections to technical processing and circulation; number and location of terminals; equipment and software features; and cost. (Six…

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)

At Indiana University the demand for word processing, the burden on the university's text processors, and the variety of commercial equipment demanded detailed, systematic technical and social planning. In the process of studying available equipment and software, the university's Office Systems Groups developed tools for evaluating the technology.…

Clarifies often misconstrued distinctions with regard to microcomputers, minicomputers, and maxicomputers. Criteria for educational use of microcomputers are examined, including its potential for language and peripheral expansion, and its communication capabilities. (MER)

The need for traps, a program routine which checks the validity of the user's response to the computer's request for input, in Computer Assisted Learning Packages, is discussed. Several example traps are described. (MK)
