- 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
- In der globalen Online-Umgebung stellen viele bibliographische Dienstleistungen integrierten Zugang zu unterschiedlichen internetbasierten OPACs zur Verfügung. In solch einer Umgebung erwarten Benutzer mehr Übereinstimmungen innerhalb und zwischen den Systemen zu sehen. Zweck dieser Studie ist, die Indexierungskonsistenz zwischen Systemen zu untersuchen. Währenddessen werden einige Faktoren, die die Indexierungskonsistenz beeinflussen können, untersucht. Wichtigstes Ziel dieser Studie ist, die Gründe für die Inkonsistenzen herauszufinden, damit sinnvolle Vorschläge gemacht werden können, um die Indexierungskonsistenz zu verbessern. Eine Auswahl von 3307 Monographien wurde aus zwei chinesischen bibliographischen Katalogen gewählt. Nach Hooper's Formel war die durchschnittliche Indexierungskonsistenz für Indexterme 64,2% und für Klassennummern 61,6%. Nach Rolling's Formel war sie für Indexterme 70,7% und für Klassennummern 63,4%. Mehrere Faktoren, die die Indexierungskonsistenz beeinflussen, wurden untersucht: (1) Indexierungsbereite; (2) Indexierungsspezifizität; (3) Länge der Monographien; (4) Kategorie der Indexierungssprache; (5) Sachgebiet der Monographien; (6) Entwicklung von Disziplinen; (7) Struktur des Thesaurus oder der Klassifikation; (8) Erscheinungsjahr. Gründe für die Inkonsistenzen wurden ebenfalls analysiert. Die Analyse ergab: (1) den Indexieren mangelt es an Fachwissen, Vertrautheit mit den Indexierungssprachen und den Indexierungsregeln, so dass viele Inkonsistenzen verursacht wurden; (2) der Mangel an vereinheitlichten oder präzisen Regeln brachte ebenfalls Inkonsistenzen hervor; (3) verzögerte Überarbeitungen der Indexierungssprachen, Mangel an terminologischer Kontrolle, zu wenige Erläuterungen und "siehe auch" Referenzen, sowie die hohe semantische Freiheit bei der Auswahl von Deskriptoren oder Klassen, verursachten Inkonsistenzen.

- 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
- Studies the quality of subject indexing by Chemical Abstracts Indexing Service by confronting authors with the particular indexing terms attributed to their computer, for 270 articles published in 54 journals, 5 articles out of each journal. Responses (80%) indicate the superior quality of keywords, both as content descriptors and as retrieval tools. Author judgements on these 2 different aspects do not always converge, however. CAS's indexing policy to cover only 'new' aspects is reflected in author's judgements that index lists are somewhat incomplete, in particular in the case of thesaurus terms (index headings). The large effort expanded by CAS in maintaining and using a subject thesuaurs, in order to select valid index headings, as compared to quick and cheap keyword postings, does not lead to clear superior quality of thesaurus terms for document description nor in retrieval. Some 20% of papers were not placed in 'proper' CA main section, according to authors. As concerns the use of indexing data by third parties, in bibliometrics, users should be aware of the indexing policies behind the data, in order to prevent invalid interpretations

- 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
- 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.
