- Abstract
- This article discusses indexing practices at the National Agriculture Library. Indexers at NAL scan over 2,200 incoming journals for input into its bibliographic database, AGRICOLA. The National Agriculture Library's coverage extends worldwide covering a broad range of agriculture subjects. Access to AGRICOLA occurs in several ways: onsite search, commercial vendors, Dialog Information Services, Inc. and BRS Information Technologies. The National Agricultural Library uses CAB THESAURUS to describe the subject content of articles in AGRICOLA.

- Abstract
- Describes an experiment comparing the performance of automatic full-text indexing software for personal computers with the human intellectual assignment of indexing terms in each document in a collection. Considers the times required to index the document, to retrieve documents satisfying 5 typical foreseen information needs, and the recall and precision ratios of searching. The software used is QuickFinder facility in WordPerfect 6.1 for Windows

- Abstract
- Indexing consistency between Library of Congress and British Library catalogers using the LCSH is compared.82 titles published in 1987 in the field of library and information science were identified for comparison, and for each title its LC subject headings, assigned by both LC and BL catalogers, were compared. By applying Hooper's 'consistency of a pair' equation, the average indexing consistency value was calculated for the 82 titles. The average indexing value between LC and BL catalogers is 16% for exact matches, and 36% for partial matches

- Abstract
- Considers the interindexer consistency between indexers working in various organisations and reports on the result of an empirical study. The interindexer consistency was low, but there were clear differences depending on whether the consistency was calculated on the basis to terms or concepts or aspects. The fact that the consistency figures remained low can be explained. The low indexing consistency caused by indexing errors also seems to be difficult to control. Indexing consistency and its control have a clear impact on how feasible and useful centralised services and union catalogues are and can be from the point of view of subject description.

- Abstract
- The biomedical book collection in the Genetech Library and Information Services was first inventoried and cataloged in 1983 when it totaled about 2000 titles. Cataloging records were retrieved from the OCLC system and used as a basis for cataloging. A year of cataloging produced a list of 1900 subject terms. More than one term describing the same concept often appears on the list, and no hierarchical structure related the terms to one another. As the collection grew, the subject catalog became increasingly inconsistent. To bring consistency to subject cataloging, a thesaurus of biomedical terms was constructed using the list of subject headings as a basis. This thesaurus follows the broad categories of the National Library of Medicine's Medical Subject Headings and, with some exceptions, the Guidelines for the Establishment and Development of Monolingual Thesauri. It has enabled the cataloger in providing greater in-depth subject analysis of materials added to the collection and in consistently assigning subject headings to cataloging record.

- Abstract
- The development of regional on-line catalogs and in-house information systems for retrieval of references provide examples of the impact of indexing theory and applications on technical processing. More emphasis must be given to understanding the techniques for evaluating the effectiveness of a file, irrespective of whether that file was created as a library catalog or an index to information sources. The most significant advances in classification theory in recent decades has been as a result of efforts to improve effectiveness of indexing systems. Library classification systems are indexing languages or systems. Courses offered for the preparation of indexers in the United States and the United Kingdom are reviewed. A point of congruence for both the indexer and the library classifier would appear to be the need for a thorough preparation in the techniques of subject analysis. Any subject heading list will suffer from omissions as well as the inclusion of terms which the patron will never use. Indexing theory has provided the technical services department with methods for evaluation of effectiveness. The writer does not believe that these techniques are used, nor do current courses, workshops, and continuing education programs stress them. When theory is totally subjugated to practice, critical thinking and maximum effectiveness will suffer.

- Abstract
- Purpose - The purpose of this paper is to examine the effect of the Helping Interdisciplinary Vocabulary Engineering (HIVE) system on the inter-indexer consistency of information professionals when assigning keywords to a scientific abstract. This study examined first, the inter-indexer consistency of potential HIVE users; second, the impact HIVE had on consistency; and third, challenges associated with using HIVE. Design/methodology/approach - A within-subjects quasi-experimental research design was used for this study. Data were collected using a task-scenario based questionnaire. Analysis was performed on consistency results using Hooper's and Rolling's inter-indexer consistency measures. A series of t-tests was used to judge the significance between consistency measure results. Findings - Results suggest that HIVE improves inter-indexing consistency. Working with HIVE increased consistency rates by 22 percent (Rolling's) and 25 percent (Hooper's) when selecting relevant terms from all vocabularies. A statistically significant difference exists between the assignment of free-text keywords and machine-aided keywords. Issues with homographs, disambiguation, vocabulary choice, and document structure were all identified as potential challenges. Research limitations/implications - Research limitations for this study can be found in the small number of vocabularies used for the study. Future research will include implementing HIVE into the Dryad Repository and studying its application in a repository system. Originality/value - This paper showcases several features used in HIVE system. By using traditional consistency measures to evaluate a semantic web technology, this paper emphasizes the link between traditional indexing and next generation machine-aided indexing (MAI) tools.

- Abstract
- Reports on an analysis of lexical ambiguity in information retrieval text collections and on experiments to determine the utility of word meanings for separating relevant from nonrelevant documents. Results show that there is considerable ambiguity even in a specialised database. Word senses provide a significant separation between relevant and nonrelevant documents, but several factors contribute to determining whether disambiguation will make an improvement in performance such as: resolving lexical ambiguity was found to have little impact on retrieval effectiveness for documents that have many words in common with the query. Discusses other uses of word sense disambiguation in an information retrieval context
