    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
    This article introduces a new concept and technique for information retrieval called 'colinked descriptors'. Borrowed from an analogous idea in bibliometrics - cocited references - colinked descriptors provide a theory and method for identifying search terms that, by hypothesis, will be superior to those entered initially by a searcher. The theory suggests a means of moving automatically from 2 or more initial search terms, to other terms that should be superior in retrieval performance to the 2 original terms. A research project designed to test this colinked descriptor hypothesis is reported. The results suggest that the approach is effective, although methodological problems in testing the idea are reported. Algorithms to generate colinked descriptors can be incorporated easily into system interfaces, front-end or pre-search systems, or help software, in any database that employs a thesaurus. The potential use of colinked descriptors is a strong argument for building richer and more complex thesauri that reflect as many legitimate links among descriptors as possible

    Abstract
    The interindexer consistency between indexers working in 10 libraries was considered. The indexing environment is described with the help of organisational theory. Interindexer consistency was low, but there were clear differences depending on whether consistency was calculated on the basis of terms or concepts or aspects. Discusses the indexing environment's connections to interindexer consistency

    Abstract
    Melvil Dewey provided generally applicable classification guidelines or rules with his classification schedules, beginning with the second edition of his scheme. Many cataloging textbooks have adopted these guidelines. Recent editions of the DDC, however, provide considerably changed, quite intricate, and edition-specific rules. The resulting two different sets of classification rules are similar in theory but very different in application. Classifiers must be aware of both sets. They are summarized in two decision charts that are intended to illustrate the differences and similarities between the two sets of rules and to encourage consistent classification decisions. The need is expressed for a parallel, end-user-oriented searching code

    Abstract
    The paper examines main problems of semantic indexing taking into consideration the connection with the needs of scientific research, in particular in the field of Social Sciences. Multi-modal indexing approach, which allows researchers to find documents according to different dimensions of research, is described. Request-oriented indexing and Pragmatic approach are also discussed and, finally, the possibility of assuming as fundamental principle, in indexing, C. S. Peirce theory of Abduction, is outlined.

    Abstract
    Purpose - This paper seeks to report a project to investigate the degree of inter-indexer consistency in the assignment of controlled vocabulary topical subject index terms to identical graphical images by different indexers at the National Library of Wales (NLW). Design/methodology/approach - An experimental quantitative methodology was devised to investigate inter-indexer consistency. Additionally, the project investigated the relationship, if any, between indexing exhaustivity and consistency, and the relationship, if any, between indexing consistency/exhaustivity and broad category of graphic format. Findings - Inter-indexer consistency in the assignment of topical subject index terms to graphic materials at the NLW was found to be generally low and highly variable. Inter-indexer consistency fell within the range 10.8 per cent to 48.0 per cent. Indexing exhaustivity varied substantially from indexer to indexer, with a mean assignment of 3.8 terms by each indexer to each image, falling within the range 2.5 to 4.7 terms. The broad category of graphic format, whether photographic or non-photographic, was found to have little influence on either inter-indexer consistency or indexing exhaustivity. Indexing exhaustivity and inter-indexer consistency exhibited a tendency toward a direct, positive relationship. The findings are necessarily limited as this is a small-scale study within a single institution. Originality/value - Previous consistency studies have almost exclusively investigated the indexing of print materials, with very little research published for non-print media. With the literature also rich in discussion of the added complexities of subjectively representing the intellectual content of visual media, this study attempts to enrich existing knowledge on indexing consistency for graphic materials and to address a noticeable gap in information theory.

    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.
