    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
    This article revisits the debate concerning controlled and natural indexing languages, as used in searching the databases of the online hosts, in-house information retrieval systems, online public access catalogues and databases stored on CD-ROM. The debate was first formulated in the early days of information retrieval more than a century ago but, despite significant advance in technology, remains unresolved. The article divides the history of the debate into four eras. Era one was characterised by the introduction of controlled vocabulary. Era two focused on comparisons between different indexing languages in order to assess which was best. Era three saw a number of case studies of limited generalisability and a general recognition that the best search performance can be achieved by the parallel use of the two types of indexing languages. The emphasis in Era four has been on the development of end-user-based systems, including online public access catalogues and databases on CD-ROM. Recent developments in the use of expert systems techniques to support the representation of meaning may lead to systems which offer significant support to the user in end-user searching. In the meantime, however, information retrieval in practice involves a mixture of natural and controlled indexing languages used to search a wide variety of different kinds of databases

    Abstract
    This study represents an attempt to compare indexing consistency between the catalogers of the National Library of Iran (NLI) on one side and 12 major academic and special libraries located in Tehran on the other. The research findings indicate that in 75% of the libraries the subject inconsistency values are 60% to 85%. In terms of subject classes, the consistency values are 10% to 35.2%, the mean of which is 22.5%. Moreover, the findings show that whenever the number of assigned terms increases, the probability of consistency decreases. This confirms Markey's findings in 1984.

    Abstract
    Report of a study comparing 2 methods of indexing: LEXINET, a computerised system for indexing titles and summaries only; and manual indexing of full texts, using the thesaurus developed by French Electricity (EDF). Both systems were applied to a collection of approximately 2.000 documents on artifical intelligence from the EDF data base. The results were then analysed to compare quantitative performance (number and range of terms) and qualitative performance (ambiguity of terms, specificity, variability, consistency). Overall, neither system proved ideal: LEXINET was deficient as regards lack of accessibility and excessive ambiguity; while the manual system gave rise to an over-wide variation of terms. The ideal system would appear to be a combination of automatic and manual systems, on the evidence produced here.

    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
    Five controlled vocabularies currently used for content representation in collections of non art moving images were examined to determine their level of conceptual compatibility. Methods borrowed from previous research in the area of indexing language compatibility were used. Quantitative data and qualitative observations allowed us to estimate more precisely and realistically the actual degree of conceptual redundancy in these indexing languages. It was found that the conceptual overlap is high enough to justify the pursuit of research and development work an a common basic indexing and access language that could be used to name objects, events, categories of persons, and relations most frequently depicted in non art moving image collections.
