CHEMICAL ABSTRACTS SERVICE (CAS), IN CONJUNCTION WITH THE NATIONAL SCIENCE FOUNDATION, CONDUCTED THE FIRST PUBLIC DEMONSTRATION OF CAS COMPUTER-BASED SUBSTRUCTURE SEARCH TECHNIQUES AT THE 152ND MEETING OF THE AMERICAN CHEMICAL SOCIETY IN NEW YORK CITY. FROM SEPTEMBER 11 THROUGH SEPTEMBER 16, 1966, INTERESTED PERSONS WERE GIVEN THE OPPORTUNITY TO…

This report explains the following mathematical techniques which may be used for relating search requests to documents contained in a library: (1) Boolean Algebraic Retrieval, (2) Linear Statistical Retrieval, (3) Statistical Association Techniques for expanding a query and/or for expanding the set of retrieval documents, (4) Vector Space…

This report outlines a generalized storage scheme for large files of highly structured data, or catalogs, and describes their realization on magnetic tape. Each datum, large or small, is assigned to one of a number of data classes of which a user may define any number. The over-all organization of a catalog is given by a map that imposes a tree…

This collection of search formulations was assembled to assist in Dialog Searching of the ERIC data base. The formulations represent modular building blocks or concepts that occur frequently when searching this file. They have been formulated and described in such a way that they can be used as given, or they can be modified to suit specific…

An experiment was conducted to identify some of the important parameters affecting search time, a critical cost factor in retrieval systems. Using actual computer searches of Chemical Abstracts Condensate, a comparison was made between the effectiveness of linear and inverted filing systems. Since the results indicated that it was the type and…

A committee on rules fur cataloging machine readable data files (MRDF) recommends areas for revision of the Anglo American Cataloging Rules to integrate collections of MRDF into the mainstream of bibliographic control. The 12 working papers which support and detail these recommendations are appended to this report. They include rationales for…

Modern technology has given us the ability to record, store, retrieve, and disseminate large volumes of data. Though technically efficient, such a procedure can be misused and thus constitute an invasion of privacy. Most school systems maintain extensive student records, but few have systematic policies regarding dissemination of such information.…

Presented are the findings of the Committee on Scientific and Technical Communication of the National Academy of Science and the National Academy of Engineering after a three-year survey of scientific and technical communication activities in the United States and abroad. There are eleven recommendations concerned with planning, co-ordination and…

Areas of concern with respect to processing, storage, and output requirements of a generalized information processing system are considered. Special emphasis is placed on multiple-access systems. Problems of system management and control are discussed, including hierarchies of storage levels. Facsimile, digital, and mass random access storage…

This document discusses problems and methods of language classification, especially with regard to questions of information storage and retrieval in connection with an information network for the language sciences such as that envisioned by the LINCS (Language Information Network and Clearinghouse System) Project at the Center for Applied…

General Information Storage, Retrieval, and Application System (GENIRAS) is a computer-aided information system designed for the storage, retrieval, and manipulation of data files. The system gives the user (1) flexibility in defining and using data bases, (2) a wide range of procedures to be applied to the data, and (3) a variety of acceptable…

The author suggests that the best guidance programs are those which allow the professional counselor the largest amount of time for counseling. The use of computers in the field of guidance assists the counselors in information storage and retrieval and provides for individualized instruction. However, the use of computers will require specific…

INFOL for the CDC 6400 is a rewrite in FORTRAN IV of the CDC 3600/3800 INFOL (Information Oriented Language), a generalized information storage and retrieval system developed by the Control Data Corporation for the CDC 3600/3800 computer. With INFOL, selected pieces of information are extracted from a file and presented to the user quickly and…

Large-scale, on-line information storage and retrieval systems pose numerous problems above those encountered by smaller systems. A step toward the solution of these problems is presented along with several demonstrations of feasibility and advantages. The methodology on which this solution is based is that of a posteriori automatic classification…

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…
