Two hundred journal articles related to fields of taxation, genetic psychology, and Shakespearean drama published from 1970-1980 were analyzed and PRECIS input strings were drawn. Occasions when input string and index entries looked incomplete and unexpressive after losing context of document are provided with solutions. Role operator schema is…

Describes a microcomputer-based string index format generated from concept networks using multiple search terms. Link weighting is highlighted as a method to decide which term appears first so the entry reflects the classification implied by the search specification. The computer software used for this system is briefly described. (Author/LRW)

An annotated bibliography of materials published during 1984-1985 on subject analysis covers classification, indexing, subject headings, and thesauri. The major theme is the need for improved subject analysis and the new computer technology is seen as the way to achieve it. (EM)

This review of the 1986 literature on subject access covers: (1) general works; (2) organization and history; (3) classification systems; (4) classification theory and method; (5) Library of Congress Subject Headings (LCSH); (6) authority control through LCSH; (7) subject searching through LC-based, assigned subject headings; and (8) other subject…

Presents adaptation of a probabilistic theoretical model previously used in relevance feedback for use in automatic indexing of documents (in the sense of imitating) human indexers. Methods for model application are proposed, independence assumptions used in the model are interpreted, and the probability of a dependence model is discussed.…

This paper reviews 19th and 20th century English-language literature dealing with the user friendliness of library catalogs and cataloging. Sections cover literature on: (1) the need for catalogs and the possibility of substituting subject bibliographies for the subject catalog; (2) user needs and the dichotomy between designing catalogs based on…

This exploration of reasons why historians do not take full advantage of government publications as sources of historical materials focuses on the difficulty of accessing information under current classification and indexing schemes. (CLB)

Selection and acquisition of relevant materials for building and developing an information infrastructure are modern worldwide problems. This document provides a core listing of journals in the earth sciences in an effort to develop a tool for the improvement of information handling and transfer. The core list was generated using several databases…

Analyzes associations among different role operators quantitatively by taking input strings from 200 abstracts, each related to subject fields of taxation, genetic psychology, and Shakespearean drama, and subjecting them to the Chi-square test. Significant associations by other differencing operators and connectives are discussed. A schema of role…

The information retrieval thesaurus emerged in operational form following a confused intellectual history as a secondary indexing aid. Prescriptive language ideas of Moore and Luhn were absent in early forms and no one attempted to reduce retrieval language as advocated earlier. DuPont retrieval thesaurus (1959) offered a model for further…

Examines the literature on the myth of "hard science-soft science" as a means of defining scientific specialties and classifying science literature, and discusses some shortcomings of scholarship in library and information science. Use of Toulmin's categorization of sciences to organize the literature and provide access for scientists is…

This review of the literature discusses theories of information with emphasis on the views of Dervin and Popper on subjectivity and objectivity as they relate to information use. Classification and indexing as applied in information retrieval systems and libraries are also discussed, and 78 references are provided. (LRW)

Investigates techniques for automatic classification of book material focusing on: computer-based surrogation of monographic material, book surrogate clustering on basis of content association, evaluation of resultant classifications. Test collection (250 books) is described with surrogation by means of back-of-the-book index, table of contents,…

Discusses the inclusion of expert systems in library and information science (LIS) education in such areas as library management, classification and indexing, and information retrieval. Emphasis is placed on involvement in developing areas such as programing and knowledge acquisition to create information professionals able to use the new…

This manual outlines a coding system for the categorization of social action performed in talking, in the context of mother-infant interaction. The system, constructed for investigating the acquisition of language for social-communicative purposes, codes talk on two levels: the single utterance, and the interchange. Both kinds of units are defined…
