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.…

To support studies in automatic indexing, classification and extracting, a general purpose frequency program was developed to further theoretical and practical understanding of text word distributions. While the program is primarily designed for counting strings of character-oriented data, it can be used without change for counting any items which…

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 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…

Vocabulary studies conducted in this century are reviewed in this paper, with an emphasis on several recent investigations utilizing computer technology. The use of computers has greatly facilitated the ease and accuracy of word tabulation, but the lists are only as language-reflective as the sources from which they are derived. The great majority…

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…

THE CREATION OF AN INDUSTRIAL SYSTEM OF MACHINE TRANSLATION WITH AUTOMATIC INDEXING OF THE TRANSLATED MATERIALS PRESUMES THE DEVELOPMENT OF DICTIONARIES WHICH PROVIDE FOR THE IDENTIFICATION OF KEY WORDS AND WORD COMBINATIONS, FOLLOWED BY THEIR TRANSLATION INTO THE DESCRIPTORS OF THE SEARCH LANGUAGE. THREE SIGNS WHICH SHOW THAT A GIVEN WORD IS A…

This document is the last of a series of eight reports of a project undertaken to (1) investigate the ways in which the National Agricultural Library (NAL) could utilize existing bibliographic data bases, (2) define the problems associated with efficient utulization of these data bases, and (3) develop approaches to solving these problems by…

This report describes how vocabulary and thesaurus techniques can be applied to a user-oriented computerized data handling system. An analysis is presented of the specialized problems associated with the development of vocabularies and rules for regulating their usage. The report consists of glossaries of action verbs and nouns accompanied by…

Objectives of this project were to develop and test a method for automatically processing the text of abstracts for a document retrieval system. The test corpus consisted of 768 abstracts from the metallurgical section of Chemical Abstracts (CA). The system, based on a subject indexing rational, had two components: (1) a stored dictionary of words…

Examines the vocabulary and communication constructs that are used by novices and domain experts to describe objects in an object identification task. Results suggest that indexing and retrieval systems should provide semantic level similarity mechanisms to allow for whole-object as well as part-wise visual analogy. The systems should also provide…

A practical machine translation system called CULT (Chinese University Language Translator), capable of translating Chinese mathematical texts into readable English, has been developed during the period 1969-1977 at the Chinese University of Hong Kong. Programs for the system are written in Standard FORTRAN and run on the ICL1904A computer system.…
