The article examines goals of information systems and basic areas that must be considered before an information system is established. The ERIC system is described as an example. Administrative organization, information processing, and problems of the system are discussed. (Author/AV)

Discussion of basic telecommunications concepts includes data terminal equipment, carrier equipment and data communications equipment. Guidelines offered for librarians planning the implementation of a telecommunications network address reliability and costs of equipment, requirements of the system, and ease of use of the system. (CLB)

Discusses the probabilistic nature of information retrieval, and describes a front end system designed to permit searchers to attach probabilistically interpreted weights to query terms, which could be adapted for conventional information retrieval systems without requiring radical changes in current indexing procedures. (37 references) (CLB)

Describes the three subsystems of an information retrieval system (document descriptions, queries, and matching algorithms) and argues that the interdependency of these subsystems requires adaptation for the system to perform when any component changes. An algorithm for redescribing documents, in response to changes in queries and retrieval rules,…

This review of the events leading to a planned materials information system in Europe focuses on national policies and actions the Commission of the European Communities. Recommendations issued by a 1982 workshop are discussed, and the objectives and development of a planned demonstrator program are outlined. (11 references) (CLB)

Based on the literature and interviews with personnel in the United Kingdom, this article identifies possible roles for information professionals in the design and development of expert systems. The need for training in expert systems, communications with computer scientists, and improved recognition of the information science profession are…

Comparison of the use in libraries of open systems--a configuration of software and hardware components from separate vendors linked by interfaces--and integrated systems considers selection of services; reliability; relationships with vendors; time needed to implement systems; and overall effectiveness of both approaches. (CLB)

Examines the role of human information processing and decision-making capabilities and limitations in the design of effective human-computer interfaces. Several cognitive engineering principles that should guide the design process are outlined. (48 references) (Author/CLB)

This description of the design of an online library acquisition system highlights the use of database management systems in developing information retrieval systems, and software requirements for the hierarchical menu-driven operation. A conceptual view of the database is included. (LRW)

An automated library routine management system was developed in-house to create system unique to the Library and Information Center, Lunar and Planetary Institute, Houston, Texas. A modular approach was used to allow continuity in operations and services as system was implemented. Acronyms and computer accounts and file names are appended.…

A major change is underway at the University of Michigan as a new telecommunications network is being installed to become the central focus for information technology on the campus as voice communication, mainframe, minicomputer, and microcomputer installations all become part of the network. (MLW)

Identifies organizational risks of end-user computing (EUC) associated with different stages of the end-user applications life cycle (analysis, design, implementation). Generic controls are identified that address each of the risks enumerated in a manner that allows EUC management to select those most appropriate to their EUC environment. (5…

Overview of expert systems (intelligent computer applications that use data, a knowledge base, and a control mechanism to solve problems) highlights history of expert systems; construction (human element, knowledge acquisition and learning, system architecture); limitations; issues and trends; and implications for information science. Thirty-three…

Encourages use of case studies to introduce "real-life" engineering assignments, suggesting that they should be given in a natural order as a series. Describes three such assignments being used at the University of the West Indies. Description, analysis, and design of an existing engineering system is included. (JM)

In this information system, sponsored research information is routinely forwarded, in machine-readable form, from NIH to Columbia, to the benefit of each. The promotion of future systems development is enhanced through the adoption of standardized data element designations and definitions. (LBH)
