- Abstract
- Online public access catalogues enable users to undertake subject searching by classification schedules, natural language, or controlled language terminology. In practice the 1st method is little used. Controlled language systems require indexers to index specifically and consistently. A comparative survey was made of indexing practices at Amsterdam and Mijmegen university libraries. On average Amsterdam assigned each document 3.5 index terms against 1.8 at Nijmegen. This discrepancy in indexing policy is the result of long-standing practices in each institution. Nijmegen has failed to utilise the advantages offered by online cataloges

- 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.

- Abstract
- An earlier article ('Cataloging must change' by D. Gregor and C. Mandel in: Library journal 116(1991) no.6, S.42-47) has popularized the belief that there is low consistency (only 10-20% agreement) among subject cataloguers in assigning LCSH. Because of this alleged lack og consistency, the article suggests, cataloguers 'can be more accepting in variations in subject choices' in copy cataloguing. Argues that this inference is based on a serious misreading of previous studies of indexer consistency. The 10-20% figure actually derives from studies of people trying to guess the same natural language key words, precisely in the absence of vocabulary control mechanisms such as thesauri or LCSH. Concludes that sources cited fail support their conclusion and some directly contradict it. Raises the concern that a naive acceptance by the library profession of the 10-20% claim can only have negative consequences for the quality of subject cataloguing created, and accepted throughout the country

- Abstract
- Purpose - To examine the degree of exact and partial match between the assigned descriptors and title keywords of medical theses written in Farsi and submitted for a PhD degree.Design/methodology/approach - A sample population of 506 theses in Pediatrics, Gynecology, Cardiology and Psychiatry was randomly picked out of a total of 909 indexed in the Indexing Department of the Central Library of the Iran University of Medical Science and Health Care Services. The results obtained are compared with those reported for other documents written in Farsi and English. Where applicable, the influence of the foreign language and its structure is commented on.Findings - It is shown that the degree of match between the assigned descriptors and the title keywords is greater than 70 per cent, equaling those reported for Farsi books and Michigan University Library catalogue in USA. It is also shown that the frequency of the match has increased since 1982, indicating that the authors have become more attentive in their choice of title.Research limitations/implications - Detailed analysis of results, however, shows significant differences between the degree of exact match amongst the four categories, with psychiatry theses that use more common terms showing highest exact match findings (50 per cent).Originality/value - This paper highlights the need for a closer collaboration with medical institutions for definition of approved terms and their incorporation in indexation in order to improve findings in various medical categories.

- Content
- The overall objective of this study was to examine the implementation of a different approach to the expression of the subject content of monographs in the cataloging record, i.e., the use of a post-coordinate, thesaurus of keywords, using inter-indexer consistency testing and in-depth analysis of mistakes in indexing. A sample of 50 non-fiction monographs was subject cataloged by 16 library science students (non-experienced indexers) using the new Hebrew Thesaurus of Indexing Terms (1996). The 800 indexing records of the non-experienced indexers were compared to the "correct indexing records" (prepared by a panel of three experienced indexers). Indexing consistency was measured using two different formulas used in previous inter-indexer studies. A medium level of inter-indexer consistency was found. In the analysis of mistakes, it was found that the most frequent mistake was the assignment of indexing terms to minor subject matter (i.e., subjects that were less than 20% of the content of the book). Among possible explanations offered for these finding are: sparseness of scope notes in the thesaurus, the priority given by Israeli public libraries to Hebrew language materials in the development of their non-fiction collection, and the size of the output of the Israeli publishing industry of non-fiction materials in Hebrew. The results of the consistency tests and the mistakes analysis were also examined in light of several factors: (1) the number of indexing terms assigned; (2) the length of the monographs (number of pages); and (3) subject area of each monograph. The same examinations were carried out for the subject cataloging records prepared by the Israeli Center for Libraries (ICL) for these monographs.

- 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.
