- Abstract
- Für eine fiktive Dokumentmenge wird eine Dokument-Wort-Matrix erstellt und mittels zweier Suchanfragen, ebenfalls als Matrix dargestellt, die Retrievalergebnisse ermittelt. Den Wörtern der Dokumentmenge werden in einem zweiten Schritt Aspekte zugeordnet und die Untersuchung erneut durchgeführt. Ein Vergleich bestätigt die schon früher gefundenen Vorteile des aspektischen Indexierung gegenüber anderen Methoden der Retrievalverbesserung, wie Trunkierung und Controlled Terms

- Abstract
- Auf der Grundlage von vier Originaldokumenten, d.h. dokumentarischen Bezugseinheiten (DBEs), wird die Indexierung in vier biomedizinischen Online-Datenbanken (MEDLINE, EMBASE, BIOSIS PREVIEWS, SCISEARCH) analysiert. Anhand von Beispielen werden inahltliche Erschließung, Indexierungstiefe, Indexierungsbreite, Indexierungskonsistenz, Präzision (durch syntaktisches Indexieren, Gewichtung, Proximity Operatoren) und Wiederauffindbarkeit (Recall) der in den Datenbanken gespeicherten Dokumentationseinheien (DBEs) untersucht. Die zeitaufwendigere intellektuelle Indexierung bei MEDLINE und EMBASE erweist sich als wesentlich präziser als die schneller verfügbare maschinelle Zuteilung von Deskriptoren in BIOSIS PREVIEWS und SCISEARCH. In Teil 1 der Untersuchung werden die Indexierungen in MEDLINE und EMBASE, in Teil 2 die Deskriptorenzuteilungen in BIOSIS PREVIEWS und SCISEARCH verglichen

- 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.
