Purpose: A mobile student information system (MSIS) based on mobile computing and context-aware application concepts can provide more user-centric information services to students. The purpose of this paper is to describe a system for providing relevant information to students on a mobile platform. Design/methodology/approach: The research…

The Current Awareness Bulletin" is discussed and the details of the mechanics of its preparation are described. (Author)

Examines the assumptions which underlie the design of SDI systems with respect to context of use, activities supported by SDI, and characteristics which make documents useful. Relates these assumptions to the failure of SDI to gain widespread acceptance among scientific information users. A 43-item reference list is included. (JL)

NASA interviewed users of its scientific and technical information system in order to assess the usefulness of the present system and to find ways to make it more effective. Emphasis was on announcement and current awareness services, the publication program, and the interactive retrieval system. (Author/LS)

The impetus for the nation-wide study of SDI (Selective Dissemination of Information) came from the desire to learn more about the options available for the application of the SDI concept prior to decisions about its possible use in Air Force research and development activities. For this purpose, data on user populations, literature coverage,…

This document contains the results of a survey of 94 U. S. organizations, and 36 organizations in other countries that were thought to prepare machine-readable data bases. Of those surveyed, 55 organizations (40 in U. S., 15 in other countries) provided completed camera-ready forms describing 81 commercially available, machine-readable data bases…

A selective dissemination of information service based on computer scanning of Nuclear Science Abstracts tapes has operated at the Atomic Energy Research Establishment, Harwell, England since October, 1968. The performance of the mechanized SDI service has been compared with that of the pre-existing current awareness service which is based on…

During the five years of activities the documentation centre at the Royal Institute of Technology has established itself as an information centre in the fields of science and technology. The SDI service is now well implemented and its activities are used and appreciated by scientists, research workers and engineers at the universities, research…

The Information and Documentation Centre of the Royal Institute of Technology Library performs research and development in information science. The two main areas of this continuing research and development programme are (1) development of a comprehensive SDI service and (2) investigations in interactive retrieval services. This annual report…

This report describes recent progress towards the provision of SDI services, current awareness bulletins, and retrospective search facilities to the potential users in Australian industry. Particular emphasis is placed on the role of periodical literature, reports, and patent literature. A list of information bulletins available from the…

The OSTI-SEA (Sociology of Education Abstracts) project was conceived as a result of the awareness that the task of SEA as a service was steadily increasing in complexity and size. A three-year project was initiated to develop a system to meet information needs, patterns of inquiry and preferences as to type of service of its users. The study…

The development of a large scale selective dissemination of information program, its experimental operation, and program evaluation is reported. An IBM 7090/94 computer program compared user interest profiles with the subject indexes of reports announced in "Scientific and Technical Aerospace Reports." Users were provided with selected…

AN OVERVIEW OF THE OPERATIONAL AND EXPERIMENTAL SYSTEMS ESTABLISHED FOR THE SELECTIVE DISSEMINATION OF SCIENTIFIC AND TECHNICAL INFORMATION (SDI) IS PRESENTED. AN ATTEMPT HAS ALSO BEEN MADE TO IDENTIFY THE TRENDS WHICH MAY SHAPE THE FUTURE DEVELOPMENT OF THE SELECTIVE DISSEMINATION PROCEDURES. THE REPORT IS BASED IN PART ON THE EXISTING SDI…

The report describes a large-scale computerized system for Selective Dissemination of Information (SDI) developed over the past five years at the U.S. Army Electronics Command to serve its technical personnel. The system, which uses as its document base the current accessions of the Defense Documentation Center, was developed in three phases: (1)…
