A proposal for a computer-aided method of building up an indexing language is made. The method involves linking terms relevant to any special retrieval system into the UDC, via a video terminal, producing a hybrid thesaurus-classification. (5 references)

An intermediate lexicon is described that employs a technique which allows, for a given subject area, the automatic translation of subject indexing from one indexing scheme into another. The lexicon was structured according to the principles of faceted classification and contained approximately 1,000 entries covering the field of library and…

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.…

Because of an absence of theory, rules and conventions for thesaurus construction and maintenance, an investigation of how thesauri are actually updated was conducted. Two concepts crucial to any theoretical foundation of thesauri and two techniques for systematic updating of a thesaurus are presented for consideration. (46 references) (Author/KE)

The field of education serves as the basis for this discussion on the use of categories in a thesaurus for information processing and documentation purposes. The author briefly shows how a number of writers concerned with the structure of the field of education, as well as makers of classification schemes, have commented on the value of setting up…

The utilization of all or most of the different possibilities to find prescribed descriptors, identifiers or new index terms in thesauri is aided by using a flow chart which is applicable to most indexing aids--thesauri or subject heading lists. (9 references) (Author)

The problem of determining the optimal cross-reference structure for a given index and for a given community of users is discussed. A cross-reference structure is represented as a graph in which the nodes are index terms and the links are relations between index terms. In order to clarify the concept of 'level of cross-referencing' the…

This new edition has the same purpose as its predecessors; i.e., to provide language which can process information relating to all aspects of economic and social development, and, at the same time, give a common dimension to the more specific vocabularies corresponding to each of them. However, it differs from previous editions on five major…

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…

The major topics included in this paper are: thesaurus structure, later developments, functions of thesauri, keyword list generation, compatibility, and maintenance and updating. (NH)

A SUBJECT HEADING AUTHORITY LIST CONTAINING MAIN ENTRIES, SCOPE NOTES, CROSS-REFERENCES, AND SUBDIVISIONS IS COMPILED, PRINTED, AND UPDATED BY COMPUTER. DESIGN CRITERIA, PROGRAMING, INPUT PREPARATION, PRINTING, AND FUTURE REFINEMENTS OF THE LIST TECHNIQUE ARE COVERED. A UNIQUE CODE WAS DESIGNED FOR SEQUENCING THE MASTER TAPE FILE AND PREPARING…

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 preliminary bibliography was prepared as a listing of background materials for use in connection with the development of an experimental thesaurus for the language sciences. The first half of the bibliography contains references to 68 sources of information on indexing materials in the language sciences. Actual indexes, lists of specialized…

Specific aspects of the thesaurus treated in this brief review are: thesaurus as a concept, classification and structure, and language compilation and control. (75 references) (NH)

Intended to facilitate the preparation of thesauri for the indexing of documents in any subject field, this report presents a set of rules pertaining to the complex issues and questions involved in indexing vocabulary development and construction. After a brief discussion of the nature, functions, and components of indexing vocabularies, a set of…
