This paper describes the content, organization, specifications, and methods of use of the CAS77 and CAS7276 online files of worldwide chemical literature, databases produced by Chemical Abstracts Service and available from System Development Corporation (SDC). The scope of the databases, their unit record, their data elements, their modes of…

THE REPORT DESCRIBES THE EFFECTS THAT A CONTROLLED VOCABULARY HAS ON THE INDEXING AND SEARCHING OPERATIONS OF THE DOCUMENT RETRIEVAL SYSTEM ESTABLISHED BY THE UNIVERSITY OF DAYTON FOR THE AIR FORCE MATERIALS LABORATORY. THE SYSTEM CONTAINS ABOUT 30,000 SCIENTIFIC AND TECHNICAL REPORTS COVERING ALL ASPECTS OF MATERIALS RESEARCH AND IS CONTROLLED BY…

DESIGNED FOR LINGUISTS AND LEXICOGRAPHERS, THE COLLECT SYSTEM CAN ANALYZE THE SYNTAX AND SEMANTICS OF RUSSIAN SENTENCES BY SEARCHING A FILE OF RUSSIAN TEXT. IN A TYPICAL SEARCH ON A GIVEN SENTENCE, GRAMMATICAL RELATIONSHIPS, INDIVIDUAL WORD SPELLINGS, AND WORD OCCURRENCES CAN BE DETERMINED. SINCE THE SYSTEM INCLUDES INTERPRETERS, THE LINGUIST CAN…

A record format and file structure for searching and editing of large textual files have been designed within the 3RIP project. This document describes: (1) general characteristics of the system; (2) implementation of the system on a DEC 10 computer in the programming language, BLISS; (3) external record format; (4) internal format; and (5) file…

The disadvantages for Canadians using the ERIC system are (1) fledgling Canadian computer information systems are deprived of their financial support; (2) Canadian research included in ERIC can not necessarily be retrieved by country of origin; (3) of the 200 journals indexed in Canadian Education Index (CEI), only 26 are to found among the 600 in…

This paper reports the results of the testing and use of a batch-mode program, QUERY, in three large computer runs performed by the ERIC (Educational Resources Information Center) Clearinghouse on Teacher Education from March through August 1970. Focus is on the behavior of QUERY as a search tool, not on cost-benefit analysis or comparison with…

Dial access information retrieval systems enable learners at remote locations to dial and receive instantaneous access to a wide range of selected audio and video materials. If such systems are to succeed and proliferate, a concerted attempt must be made to produce software based on student and curricular needs; a program must be constructed which…

A five-year development program plan was drawn up for the Defense Documentation Center (DDC). This report presents in summary form the results of various surveys and reviews performed in selected areas of micrographics to support the efforts of the program's planners. Exhibits of supporting documentation are presented, together with a discussion…

This year's annual report of COSATI contains the history, charter, and accomplishments of the committee since its inception in 1962. Agency reports are arranged by subject developments that cut across departmental lines. Significant advances in technical communications are reported, as well as some management information systems. In addition, the…

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…

Primary research journals and meetings have long been the principal vehicles for communicating science information within the physics and astronomy community. Both vehicles have been slowly and subtly running into major problems because of expanding sizes and goals of the community, growing interdependencies of subject areas and increasing need…

SPIRES (Stanford Public Information REtrieval System) is a computer information storage and retrieval system being developed at Stanford University with funding from the National Science Foundation. SPIRES has two major goals: to provide a user-oriented, interactive, on-line retrieval system for a variety of researchers at Stanford; and to support…

Descriptions of representative nonconventional information systems in use today are given in order to provide managers, management analysts, supervisors, and others with ideas as to how they might improve the dissemination, storage, and retrieval of information in their offices. No attempt was made to evaluate the relative merits of the systems…

Indexing and abstracting can be thought of as a way of modeling an actual document or textual item. Both are miniature versions of the actual thing. Normally, the indexing model is used to locate desired information, while the abstracting model is used as a screening medium to help the searcher decide which of the apparently correct actual items…

The research has contributed toward establishing a discipline of information science since it shows that fundamental principles dealing with communication exist and can be applied to pracitcal problems. Several courses and Ph.D. dissertations grew out of the research. (Author)
