Reviews research on data mining (DM) and knowledge discovery (KD). Discusses popular conceptions of information growth, the knowledge acquisition process, major elements of the DM process, and evaluation methods. Research on DM and KD is divided into two categories: analysis of numerical databases and analysis of non-numerical or textual…

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…

Investigates the combination of terms and document weighting functions in information retrieval. Describes weighting functions based on how information is used within documents and collections and uses them in two types of experiments: one based on combination of evidence for ad hoc retrieval, and one within a relevance feedback situation.…

Designed to minimize information overload in telecommunications systems, the formal model developed in this paper predicts the usefulness of a message based on the available message features, and may be used to rank messages by expected importance or economic worth. The assumptions of binary and two Poisson independent probabilistic distributions…

This study has as its main object the formulation of an approach, as global and comprehensive as possible, to the multiple aspects of the engineer's needs for scientific and technical information. The basis of the study is an analysis of the engineer's role, its characteristics, different specialties, levels of training, and categories of…

THE DEVELOPMENT OF AN OBJECTIVE STRATEGY FOR THE SELECTION OF JOURNAL LITERATURE IN THE RETRIEVAL OF READING RESEARCH IS DESCRIBED. A FREQUENCY COUNT WAS MADE OF THE ARTICLES APPEARING IN THE GRAY SUMMARIES OF READING RESEARCH PUBLISHED ANNUALLY BY THE READING RESEARCH CENTER OF THE UNIVERSITY OF CHICAGO. THE JOURNALS FOR THE PERIOD 1884 TO…

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…

Researchers make little or no use of formal information systems. This is due, not so much to 'information apathy' on their part, as to faults inherent in information services as a whole. A formal information service may not come through at all. It is not capable of reaching behind a request to the real question that motivated it. By not being able…

In pursuance of resolution 2.141 (a) adopted by the General Conference at its sixteenth session (October-November 1970), the Intergovernmental Conference for the Establishment of a World Science Information System (UNISIST) was organized by Unesco. The purpose of the Conference held October 4-8, 1971 was to make recommendations covering the basic…

Computers make possible a variety of investigative and enforcement techniques. However, the technology of systematic data searching is subject to at least six sources of error, e.g., incorrectly entered data, none of which can be completely eliminated. Thus, a thought police as envisioned by Orwell remains a technological fiction. (RM)

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)

Reviews research findings on the effects of user fees in online searching, and concludes that charging does discourage use of computerized retrieval systems. It is recommended that alternatives to direct user fees be sought whenever possible. (SW)

A LARGE BODY OF EDITED PRESENT-DAY AMERICAN ENGLISH, FROM A RANDOM SAMPLE OF MATERIAL PUBLISHED FOR THE FIRST TIME IN 1961, WAS PREPARED IN A FORMAT BY WHICH IT CAN BE TRANSFERRED TO MAGNETIC TAPE FOR USE IN DIGITAL DATA-PROCESSING EQUIPMENT. FIVE HUNDRED SAMPLES, OF 2,000 WORDS EACH, OF INFORMATIVE AND IMAGINATIVE PROSE WERE CHOSEN, EXCLUDING…

The Florida R & D Utilization Project has two major goals: to provide schools with access to the best available R & D products and practices to resolve local needs, and to assist schools in developing a capacity for diagnosing and resolving instructional and other problems. This paper describes the 7-step conceptual model that governs the…
