Describes plans of 3-year experimental program organized jointly by two universities aiming to assess cost, efficiency, and subjective impact of an electronic journal system (uses computer to aid procedures whereby article is written, refereed, accepted, and published), and to explore and evaluate alternative forms of user communication. Sixteen…

Describes the online catalog in a university library, including the database, the database index, user instruction, the command language and search capabilities, functions of various commands, statistics generated to monitor system use, and hardware for both public access and staff use. (CHC)

Five papers discuss factors affecting human interactions with online information systems. Topics covered include the use of discourse analysis for interaction functions specification; the impact of optical data disks; the need for research into the search process; user access to data dictionaries; and the development of full text systems. (CLB)

Discusses uses of technology in distance education and describes a study of college graduate students that illustrated the effects of two different instructional delivery technologies on the nature of interaction in online education systems: one used a synchronous video link-up and one used an asynchronous computer-mediated communication system.…

This paper proposes a model for a general interface between people and Computer Algebra Systems (CAS). The main features in the CAS interface are data navigation and the possibility of accessing powerful remote machines. This model is based on the idea of session management, in which the main engine of the tool enables interactions with the…

A study was conducted in September 1981 of factors which influence the process of communication between clients and staff at six high-capacity computer facilities in the Sacramento, California, metropolitan area. These included two large government organizations, a medium-sized corporation, two bibliographic database settings, and a computer…

Presented are variables and conditions for design of a computer-based adaptive instructional system. The design strategy uses Bayes' theory of conditional probability to determine an instructional sequence according to individual student characteristics and needs. The adaptive strategy uses prior estimates based on student pretask and on-task…

The command language features of 11 on-line information retrieval systems are presented in terms of the functional needs of a searcher sitting at a terminal. Functional areas considered are: becoming familiar with the system, receiving help when in trouble, regulating usage, selecting a data base, formulating simple queries, expressing single…

A ten-year research study designed a mechanized information system in the information processing field. Special attention was paid to implementation criteria entering into on-line retrieval through man-machine dialog from a remote typewriter or video terminal and four major areas were investigated: search strategies, machine stored indexer aids,…

This composite report provides summaries of presentations by 10 experts at the 23rd Annual Clinic on Library Applications of Data Processing in April 1986 at the University of Illinois at Urbana-Champaign. All were concerned with the design of online systems to make them easier for library patrons to use. (Author/CDD)

Seven articles present history and overview of an academic online catalog. Highlights include linking of the library circulation system with the full bibliographic record system; planning and maintenance of an online catalog; effect of the online catalog on reference (uses, services, personnel); and a microcomputer-based user interface. References…

Describes the design of a prototype adaptive online catalog that was implemented as a transparent workstation-based front end system to MELVYL, the online catalog for the University of California libraries. Problems with searching bibliographic retrieval systems are reviewed, including irrelevant retrievals and the inexperience of most users.…

This 22-paper collection addresses a variety of issues related to representation and transfer of knowledge. Individual papers include an explanation of the usefulness of general scientific models versus case-specific approaches and a discussion of different empirical approaches to the general problem of knowledge representation for information…

Design theory should identify candidate designers, specify design behavior to be measured, and discriminate between behavior of designers and nondesigners. A study evaluated different formats of computerized structural display and data entry to measure design behavior. A program using graph theory as an internal data structure in the computer and…

Research and development work on the use of the SCHOLAR autotutorial, online system is described. Inference strategies used within the system are deductive, negative, and functional in character. A graphics package allows user to ask questions and give commands in English to control SCHOLAR's map display capability. The examples shown are for…
