The four chapters included in this report are based on LINCS project activities undertaken since 1968, with an emphasis on indexing tools in the language sciences and related problems. Chapter one, "Indexing Tools for the Language Sciences: Methodology," discusses the development of a LINCS thesaurus and its role in the LINCS network.…

The development of the INSPEC vocabulary system which comprises a unified indexing and classification scheme is described together with the reasons for its adoption. (Author)

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…

A punch-card, optical coincidence information retrieval system has been designed for the information needs of a small library specializing in drug abuse literature. (Author)

This report presents the identification and definitions of subject oriented engineering and scientific disciplines and fields which are included in the EDIS Subject Categories. The discussion is extended to include the mix of subjects with other orientations, such as Item, Mission-Project, Expertise and Data Bank Categories. Sample queries are…

ONE OF THE PROBLEMS IN INFORMATION STORAGE AND RETRIEVAL SYSTEMS OF TECHNICAL DOCUMENTS IS THE INTERPRETATION OF WORDS USED TO INDEX DOCUMENTS. SEMANTIC TOOLS, DEFINED AS CHANNELS FOR THE COMMUNICATION OF WORD MEANINGS BETWEEN TECHNICAL EXPERTS, DOCUMENT INDEXERS, AND SEARCHERS, PROVIDE ONE METHOD OF DEALING WITH THE PROBLEM OF MULTIPLE…

Reexamines the feasibility of automatic thesaurus generation by establishing a framework for analyzing the degree of correspondence between automatically generated thesauri and a thesaurus of the same terms constructed by subject specialists. (Author/FM)

This paper on Thesauri in Educational Documentation attempts to show by description and analysis the difference in application between thesauri and classification schemes as indexing languages in documentary information systems, and from this to infer possible future developments. First, the differences between the pre-coordination and…

This is the fifth in a series of eight reports of a research study for the National Agricultural Library (NAL) on the effective utilization of bibliographic data bases in machine readable form. NAL desires ultimately to develop techniques of interacting with other data bases so that queries put to NAL may be answered with documents or document…

This experiment used five index languages to form nine different index files to the same collection of documents. Each index term, in each language, was treated in two ways: as an independent English term, and as a coded entry in a faceted-type thesaurus which specified relationships between terms. The performance effect of the thesaurus was then…

The aim of the conference was to hold a working discussion on problems essential to the building of thesauri, a uniform comprehension of which would make it possible to build them in a manner ensuring easier communication and exchange of information between information systems covering different ranges of subject matter, and using different…

For information storage and retrieval, a thesaurus is used during indexing and searching processes to translate from natural language into a more restricted retrieval system language. The purpose of this thesaurus is to control the language used to index and retrieve documents of interest to Social and Rehabilitation Service (SRS) and the…

Procedures for coordinate indexing are described and the importance of a controlled vocabulary common to indexer and searcher discussed. (Author)

Contained are listings of descriptors used to index the literature in the National Criminal Justice Reference Service (NCJRS) documentation data base, and to store and retrieve information about the literature for users of the service. Term selection is determined by the vocabulary used in the documents input into the system, the frequency of term…

This report discusses the problem of the meansings of words used in information retrieval systems, and shows how semantic tools can aid in the communication which takes place between indexers and searchers via index terms. After treating the differing use of semantic tools in different types of systems, two tools (classification tables and…
