The purpose of the present study is to explore cost-effectiveness factors that affect the choice among alternative system designs for retrospective searching services. A cost-effectiveness model that may be used to evaluate potential systems was derived, and a statement of the general magnitude of costs that the American Psychological Association…

A program is presented for a National Information System for Physics based on a computerized American Institute of Physics (AIP) Information Service which is designed to augment the element of selectivity of the present information system for user interests. It is proposed that the system be developed in discreet stages, each adding to the…

PROBE, a search and retrieval program, was developed in 1970 at Indiana University to search the computer tape bases for the two ERIC publications, "Research in Education" (RIE) and "Current Index to Journals in Education" (CIJE). The ERIC tapes are received, converted, and combined at the University and implemented on the…

A statistical model for characterizing the growth patterns of data base utilization and for estimating future utilization levels of demand has been developed for information retrieval organizations. Illustrations of the model applied to a typical information retrieval organization are given and discussed. (5 references) (Author)

Presents an abstract for a planned session on the need to coordinate user studies and information retrieval system design research. Topics include human-based research and system-based research; children's information use; usability and cartographic information systems; and ethnomethodology and system design. Panelists included: Nick Belkin, Dania…

The primary purpose of the Conference was to emphasize the value of technical information to leaders of British industries by relating the use of technical information to economic development, showing that there are weaknesses in the collection and use of technical information, trying to cost these failings, and indicating some of the remedial…

The traditional concern with relevance or nonrelevance of unexamined documents is misplaced, and traditional measures of effectiveness should be replaced by estimates of direct utility of examined documents. (Author)

The University of Georgia Information Dissemination Center is profiled. Emphasis is on the organization and services of the system which primarily serves 27 state supported schools in Georgia. Based on a recent survey, the impact of the service on the users is discussed. (DH)

The design, implementation and operation of the Computer Search Center of IIT Research Institute, an information center to educate and link industry and academic institutions to chemical and other scientific information systems, is described. Format conversion, profile input, search and output programs developed over a two-year period are detailed…

The ERIC information system is designed for computerized information storage and retrieval. While the computer can play an increasingly more vital role in facilitating reference searches of large literature collections, experience shows that manual searching gives the user skills and expertise that are essential to effectively use the computerized…

Text similarity measurements are used to determine relationships between natural-language texts and text excerpts. The resulting linked hypertext maps can be broken down into text segments and themes used to identify different text types and structures, leading to improved information access and utilization. Examples are provided for text…
