An information retrieval system based on superimposed coding

Abstract: The cost of storing information in machine-accessible form has declined markedly in the last decade, and promises are such that one can look forward to having complete libraries available in such form. This places increased importance on algorithms which make it possible to search large files efficiently.

Interactive search and retrieval methods using automatic information displays

Abstract: Throughout the world, the design and operation of large-scale information systems has become of concern to an ever-increasing segment of the scientific and professional population. Furthermore, as the amount and complexity of the available information has continued to grow, the use of mechanized or partly mechanized procedures for various information storage and retrieval tasks has also become more widespread. While a number of retrieval systems are already in operation in which the search operations needed to compare the incoming information requests with the stored items are performed automatically, no systematic study has ever been made of the use of man-machine interaction as a part of a mechanized text analysis and information processing system. Specifically, the recent development of high capacity random-access storage mechanisms and conversational input-output consoles should permit a rapid interchange of information between users and system. Such an interchange can then be used to produce improved search formulations, resulting in a more effective retrieval service.

Toward a Viable Classification Scheme: Some Theoretical Considerations.

Abstract: Drawing on current psychological, philosophical, and rhetorical theories, a scheme is presented which will allow the classification, indexing, and retrieval of information using content-free cues. The system is patterned after that of human information retrieval and with current software packages can be completely computerized.

On Information Storage Models.

Abstract: The transfer of information through space and time in communication systems is often accompanied by significant delays which give rise to meaningful storage problems. Mathematical model have been developed for the study of these kinds of problems which are applicable to the design of manual, library-type, or mechanized information storage and retrieval systems. This state-of-the-art review of such models divides the subject into three kinds of storage models: those concerned primarily with spatial efficiency, those concerned with usage and cost, and those concerned with retrieval accuracy.

Information Retrieval for the Working Scientist: A Simple Algorithm

Abstract: Many scientists collect and maintain citations, references, and reprints in diverse forms. Investigators differ in the use, intensity, and breadth of their collections. The effort may be motivated by potential use to students and colleagues or may exist only long enough to deal with a particular problem or research project. All collections are subject to problems of care, cataloging, storage, and probably most important, of retrieval. Some workers have developed complex indexing procedures and some have given up and just stick them in boxes by author or date or some vague subject categorization. Several characteristics of modern digital computers afford some aid in solving the information retrieval problems. Many universities have time available to faculty and some have terminals available in most departments. Many installations have tape and disc storage and most serious workers have cardreading devices available within a short walk. Yet few investigators have computerized their efforts, preferring to await the future (Brown et al., 1967). Meanwhile, they expend time and effort in frustrating searches or extensive indexing. Computerized information retrieval of his own material is available

Phrase Dictionary Construction Methods for the R2 Information Retrieval System

Abstract: : The R2 Information Retrieval System, when complete, will be a question-answer information retrieval system in which a person, having questions over a pre-determined data base, will be able to receive answers to his questions. The paper concerns the initial processing of the data base for the R2 system and explores initially several simple strategies for retrieving relevant statements, rather than answers, for a given question over the data base. The paper is first concerned with the construction of a 'phase dictionary' from the data base, and, secondly, with the development of several initial attempts for information retrieval from the data base.

The development of an information storage and retrieval system for combustion research

Abstract: The development of, and initial operating experience with, a multiple‐access information retrieval system is described. Based upon the use of eighty‐column punched cards and the ICT 302 Sorter, it was devised specially for, and with the active co‐operation of, research scientists concerned with the fundamental aspects of combustion. The content and arrangement of the classification scheme used is outlined. A preliminary analysis is made of the searching techniques applied to, and the retrieval response for, the inquiries received from research scientists during the first two years of operation of the retrieval system.
