Presents an operational definition of personal information retrieval systems and describes design principles of current applications and existing systems, current trends, and research guidelines for general design principles. (4 references) (Author/CLB)

Describes the inability of traditional subject index terms to represent relational information among concepts, and the development of frame based knowledge representation methods that provide relational semantic representations of documents and user queries. The discussion covers research in user interfaces and automatic document classifications,…

Describes the use of machine aided indexing as part of NASA's information systems. The discussion covers reasons for incorporating machine aided indexing, the lexical dictionary used, subject switching, natural language processing, benefits to the system, and possible future developments. (CLB)

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)

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)

Discusses the impact of research in artificial intelligence and human computer interaction on the design of bibliographic information retrieval systems, and presents design principles of a prototype system that uses semantically based searches and a knowledge base consisting of conceptual frames. (10 references) (CLB)

The most time consuming and expensive step in developing expert systems is knowledge acquisition (KA), and it is important to determine how the limited resources for acquiring knowledge should be allocated across different sources. This paper develops a model that determines how KA resources should be spent and how such a model may be used. (23…

Describes the development of Bookshelf, a multi-user microcomputer system for small libraries that uses an integrated software package. The discussion covers the design parameters of the package, which were based on a survey of seven small libraries, and some characteristics of the software. (three notes with references) (CLB)

The impact of emerging information technologies on the information industry is discussed in four papers. Topics covered include electronic delivery of full text primary literature; a brief evaluation of new information processing technologies and software; networking technologies; and the use of gateway technologies to create new products and…
