Information retrieval (IR) systems have tremendously broaden users' access to information. However, users need to select their needs from trillions of information indexed daily. Due to the "semantic gap" between queries and indexed terms in IR system, whether users can satisfy their needs depends on whether they use the correct terms as…

In information systems development, end-users have shifted in their role: from consumers of information to informants for requirements to developers of systems. This shift in the role of users has also changed how information systems are developed. Instead of systems developers creating specifications for software or end-users creating small…

User clustering algorithms have been introduced to analyze users' learning behaviors and help to provide personalized learning guides in traditional Web-based learning systems. However, the explicit and implicit coupled interactions, which means the correlations between user attributes generated from learning actions, are not considered in these…

Describes the experience accumulated by the United Nations and its agencies during the last decade in the international information system field. Bibliographic, statistical, and resource systems are described, and common features are identified; in addition, a model for strengthening national information capabilities and for sharing information is…

A Career Education Document Information System (CEDIS) Project was funded September 1, 1971, for the purpose of establishing more effective communication links between the occupational educators who need to obtain new knowledge and acquire improved skills. During the first year of operation, several major accomplishments were achieved, including:…

A generalized framework for developing analytical and conceptual relationships involving the flow of information has been suggested. This paper provides further refinement, rigor, and extension for some of the earlier relationships suggested. In particular, a measure of the amount of information is defined as the difference of the value of the…

With the advent of the microcomputer, end users need personal information systems that work both at the office and at home and in the external world. The librarian's role could extend from being an information service provider to being a professional counselor on personal information management. (41 references) (MES)

Ten assumptions about the next 25 years are outlined, a model state level information system is set forth, and a forecast of the impact of such a model state sponsored service in the year 2000 is attempted. (Author/PF)

Considers nature of information-seeking in terms of decision making and problem solving, dynamics of process, and value of information. Basic psychological studies, effects of cognitive style, human behavior models, and design issues (attributes and evaluation of information systems, analysis of information needs, information seeking aids) are…

Discusses a reliability theoretic construct focusing on information produced to satisfy specified purposes or achieve preconceived objectives. When measures of system reliability and sensitivity analyses are performed, the result is a closer congruence between the objectives of the data producer and user requirements. (Author/MBR)

A study looked at the possibilities for a user-based information system which could provide usable structured information about educational technology and attempted to determine how best to supply information about educational process to users. The study had three phases. The first surveyed the literature and activities of centers concerned with…

Recommends that Medical School libraries be equipped to organize and provide biomedical information services in their respective states or areas, as a basis for the development of a national library-based biomedical information network to support Nigeria's programs of medical education, research, and health care delivery at all levels. (VT)

Presents a model of human information needs which classifies information need types by their inherent properties. The influence of information needs on human behavior, and the need to incorporate this concept into information storage and retrieval systems, are discussed. (15 references) (CLB)

Introduction: To provide valuable services in the future, libraries will need to create better information systems and set up an infrastructure more in line with the current technologies. The "Functional Requirements for Bibliographic Records" conceptual model provides a basis for this transformation, but there are still a number of…
