    Abstract
    Our purpose is to adapt a statistical method for the analysis of discrete numerical series to the keywords appearing in scientific articles of a given area. As an example, we apply our methodological approach to the study of the keywords in the Library and Information Sciences (LIS) area. Our objective is to detect the new author keywords that appear in a fixed knowledge area in the period of 1 year in order to quantify the probabilities of survival for 10 years as a function of the impact of the journals where they appeared. Many of the new keywords appearing in the LIS field are ephemeral. Actually, more than half are never used again. In general, the terms most commonly used in the LIS area come from other areas. The average survival time of these keywords is approximately 3 years, being slightly higher in the case of words that were published in journals classified in the second quartile of the area. We believe that measuring the appearance and disappearance of terms will allow understanding some relevant aspects of the evolution of a discipline, providing in this way a new bibliometric approach.

    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
    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

    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.
