Uses and sources of voice indexing (a look-up feature for recorded materials) are discussed. Voice indexing enables a blind user of audiocassettes to find specific sections of recorded text independently. A procedure for sequential voice indexing on a two-track or four-track cassette recorder is described. (JW)

Reviews different structures and techniques of knowledge representation: structure of database records and files, data structures in computer programming, syntatic and semantic structure of natural language, knowledge representation in artificial intelligence, and models of human memory. A prototype expert system that makes use of some of these…

Describes and discusses the findings of an experiment that tested the precision of full-text retrieval enhanced by 29 document term weighting algorithms at the lowest, middle, and highest levels of recall, and compared with the precision of full-text retrieval without algorithms and with paragraph retrieval. (29 references) (Author/CLB)

Describes how Murray State University Library, a medium sized academic library in Kentucky, made use of an IBM mainframe and SCRIPT, a text formatting program to index two local newspapers. The entire procedure is described, including indexing, authority lists, input techniques, editing, and production and distribution of the index. (CLB)

Discusses the difficulties encountered in accessing online information on women and women's issues that results from the indexing of relevant items across several databases. A project designed to index literature on employment, equality, and gender within a single database is described. (CLB)

Describes research which measured the efficiency of role operators through frequency of appearances in PRECIS input strings for 200 abstracts related to taxation, genetic psychology, and Shakespearian drama. Frequencies of appearance of major categories of role operators, role operators in different subjects, individual main line operators, and…

Reports on axiomatic approach to systems design that has emanated from documentation work in field of chemistry and closely related disciplines. It is based on five axioms: definability, order, sufficient degree of order, representational predictability, and representational fidelity. Mandatory indexing is discussed; a glossary is appended. (106…

Review of office filing facility filing and retrieval mechanisms for unstructured and mixed media information focuses on free text methods. Also discussed are the state of the art in handling voice and image data, problems with searching text surrogates to implement free text content retrieval, and work of Project Minstrel. (Author/MBR)

Arguing that inadequacy of subject access in online catalogs lies with the database used as a foundation, this essay discusses the weaknesses of Library of Congress subject cataloging and MARC records, electronic card catalogs, enhancement of data, publisher warnings, Boolean search strategy inadequacies, and changes in the national standard. (EJS)

This paper reviews indexing theory and suggests that information retrieval can be significantly improved by applying basic indexing criteria. Indexing practices are described, including the three main types of indexes: pre-coordinate, post-coordinate, and variants of both. Design features of indexes are summarized, including accuracy, consistency,…

This paper presents some of the efforts currently being made to develop mechanisms that can organize World Wide Web resources for efficient and effective retrieval, as well as programs that can accommodate multiple languages. Part 1 discusses structural approaches to organizing Web resources, including the use of hierarchical or…

Library classification at the Croatian library school of the Department of Information Sciences, University of Zagreb (Croatia) has an important place in the department's curriculum. This is due to the fact that classification is the most important indexing language in Croatian libraries and documentation centers and services, and its role has not…

English has become the primary language of most information retrieval tools. This makes it almost impossible for the non-English speaking world to take advantage of American abstracting and indexing services. One solution to this problem is to use the Universal Decimal Classification (UDC) as a switching language. (Author/DH)

Construction planning, vocabulary base development, and term analysis and grouping are the main subjects treated in this paper. (NH)

Computerization seems to offer some solutions to the inadequacies of the card catalog. However, vocabulary obstacles must be overcome before the history, art history, and art students alike can enter libraries all over the world and quickly satisfy their various needs. (10 references) (Author/NH)
