DATA COLLECTED FROM 15 YEARS OF PSYCHOLOGICAL TESTING UNDER THE APTITUDES RESEARCH PROJECT IN THE DEPARTMENT OF PSYCHOLOGY, UNIVERSITY OF SOUTHERN CALIFORNIA, WERE MICROFILMED OR KEYPUNCHED AND MADE AVAILABLE TO EDUCATORS, PSYCHOLOGISTS, AND GRADUATE STUDENT RESEARCHERS. EACH TEST HAD BEEN ADMINISTERED TO ABOUT 600 EXAMINEES. STUDENT HAND-WRITTEN…

This is a progress report on a project attempting to design a system of compacting text for storage appropriate to disc oriented demand searching. After noting a number of previously designed methods of compression, it offers a tentative solution which couples a dictionary of most frequent character-strings with a set of variable-length codes. The…

The chair of scientific information at the Leningrad State Institute of Culture has worked out a preliminary syllabus on informatics for the Technical Libraries Department. The syllabus comprises the following topics: Informatics as a scientific discipline, Organization of information work, Information provision techniques, Information retrieval…

The unclassified and unlimited bibliography compiles references dealing specifically with the role of computers in information sciences. The volume contains 239 annotated references grouped under three major headings: Artificial and Programming Languages, Computer Processing of Analog Data, and Computer Processing of Digital Data. The references…

Reported is a compilation of the data collected from a comprehensive evaluation of the Information Retrieval Center of the Northern Colorado Educational Board of Cooperative Services (NCEBOCS) The evaluation consists of an historical review of the Center (1967-1970), analysis of requests received, user reactions to the services, interviews with…

Describes the data bases and programs of numerous on-line retrieval systems for chemical information, including mass spectra, NMR, x-ray, and substructure data. (MLH)

Northwestern University's Remote Information Query System (RIQS), an information storage and retrieval system characterized by a mixture of data structures for the internal record organization, is discussed. On-line and batch mode search capabilities handle both textual and quantitative information. Other system characteristics, capabilities and…

Four operational systems for searching and retrieving information from the ERIC data base are described. (NH)

Computer programs have been written which enable substructure searches to be carried out on a file of compounds ciphered using a modified version of the IUPAC (Dyson) notation. The search system outlined is to be linked with one which uses input from the chemical structure typewriter. (3 references) (Author)

A hierarchical extension to the American National Standard for Bibliographic Information Interchange on Magnetic Tape is defined and described. The accommodation of the extension within the existing standard is discussed, modifications to the existing standard are proposed, and applications of the hierarchical format are presented. (21 references)…

Today, collecting, evaluating, and analyzing data--the basic concepts of scientific study--usually involves electronic probeware. Probeware combines sensors that collect data with software that analyzes it once it has been sent to a computer or calculator. Science inquiry has benefited greatly from the use of electronic probeware, providing…

This manual on microcomputer-based database management programs provides a description of the key characteristics of database software as well as guidelines for designing a database, uses of database programs, and selecting the right software. Three sets of concepts related to database management are listed and explained: creating a database,…

Reports on a series of programs that have been developed to process data bases, consisting of textual items, and to index and arrange (classify) the data items in accordance with an automatically generated classification system. (Author)

This report presents the rationale, motivation, and formal description underlying the General Retrieval and Information Processor for Humanities Oriented Studies (GRIPHOS) Management Information System. This system was devised to handle "card catalog" types of information; perform searches that are usually carried out in archives,…

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…
