    Abstract
    The patterns of overlap between terms which are closely related in a thesaurus are considered. The relationships considered are parent/child, in which one term is a broader term of the other, and sibling in which to 2 terms share the same broader term. The patterns of overlap observed in the MeSH thesaurus with respect to selected MEDLINE postings are examined. The implications of the overlap patterns are discussed, in particular, the impact of the overlap patterns on the potential effectiveness of a proposed algorithm for handling negation is considered.

    Abstract
    Die Vorteile internationaler Verbundsysteme werden durch Schwierigkeiten bei der Inhaltserschließung gefährdet. Abweichungen des tatsächlichen Selektionsergebnisses vom gewünschten Selektionsziel sind sprachlich bedingt; sie werden insbesondere durch Polysemie, Kontextabhängigkeit und syntaktische Ambiguität verursacht. Unter mehrsprachigen Bedingungen verschlechtert sich die Selektivität; es entstehen sprachabhängig unterschiedliche Selektionsergebnisse. Verbesserung ist nur bei Schaffung und sachgerechter Anwendung eines solchen multilingualen Thesaurus zu erreichen, der größtmögliche semantische Isomorphie (klare und übereinstimmende Begriffsabgrenzung) zwischen den Vokabularen und exakte semantische Äquivalenz zwischen den Deskriptoren gewährleistet. Dies erfordert hohe Aufwendungen, ist aber wichtiger als die Speicherung großer Mengen schlecht selektierbarer Dokumentationseinheiten

    Abstract
    Bei der Pilotstudie DB-Thesaurus ging es um die Untersuchung der Art und Form der von der Deutschen Bibliothek für ihre Inhaltserschließung verwendeten Schlagwörter und ihre Eignung als Elemente eines allgemeinen Thesaurus für Bibliotheken. Der Abschlußbericht (Arbeits- und Ergebnisbericht) beantwortet die in der Ausschreibung ausgesprochenen Fragen bezgl. der Möglichkeiten und Grundprinzipien eines solchen Thesaurus der DB-Schlagwörter, insbesondere auch seiner Struktur (Umfassung der Fachgebeiete, Anzahl der Hauptgruppen, Erschließungstiefe), seiner Relationsarten (begriffliche und terminologische), der Möglichkeiten der Wortschatzbegrenzung, der Behandlung von Eigennamen und der Möglichkeiten der Terminologiekontrolle. Die Untersuchung ergab, daß sich die SW der DB als Thesauruselemente eignen, daß diese aber um viele Begriffe ergänzt werden müssen, die teilweise aus dem Schatz der DB-Verweisungen gewonnen werden könnten, wenn man einen systematisch angelegten, allgemeinen Thesaurus auf dieser Basis erstellen will. Unter den Anlagen befindet sich als Beispiel dafür, daß DB-Schlag- und Verweisungswörter zur Thesauruserstellung herangezogen werden können, ein sog. Sportthesaurus, der nur durch einige fehlende Oberbegriffe ergänzt wurde. Der gesamte systematische Teil ist im alphabetischen Teil enthalten. Auf die Unterscheidung der Abstraktionsrelation von der Bestandsrelation wurde auch im alphabetischen Teil besonderer Wert gelegt

    Abstract
    Im Jahre 1978/79 wurde bei der Deutschen Bibliothek eine Pilotstudie durchgeführt, in der die zur Indexierung der in der Reihe A der Deutschen Bibliographie ("Wöchentliches Verzeichnis") verwendeten Schlagwörter auf ihre Brauchbarkeit als Deskriptoren eines Allgemeinen Thesaurus für Bibliotheken untersucht werden. Es sollten die Grundprinzipien eines solchen Thesaurus darsgestellt, und seine Struktur (Fachgebiete, Anzahl der Hauptgruppen, Erschließungstiefe), die Möglichkeiten der Wortschatzbegrenzung, die Behandlung der Eigennamen und die Möglichkeiten der Terminologiekontrolle untersucht werden. Es zeigte sich, daß sich die Schlagwörter der DB sehr wohl als Thesauruselemente eignen, daß sie aber um viele Begriffe ergänzt werden müssen, um den Zusammenhang der Hierarchieebenen herzustellen

    Abstract
    Calvin Mooers' work toward the resolution of the problem of ambiguity in indexing went unrecognized for years. At the time he introduced the "descriptor" - a term with a very distinct meaning-indexers were, for the most part, taking index terms directly from the document, without either rationalizing them with context or normalizing them with some kind of classification. It is ironic that Mooers' term came to be attached to the popular but unsophisticated indexing methods which he was trying to root out. Simply expressed, what Mooers did was to take the dictionary definitions of terms and redefine them so clearly that they could not be used in any context except that provided by the new definition. He did, at great pains, construct such meanings for over four hundred words; disambiguation and specificity were sought after and found for these words. He proposed that all indexers adopt this method so that when the index supplied a term, it also supplied the exact meaning for that term as used in the indexed document. The same term used differently in another document would be defined differently and possibly renamed to avoid ambiguity. The disambiguation was achieved by using unabridged dictionaries and other sources of defining terminology. In practice, this tends to produce circularity in definition, that is, word A refers to word B which refers to word C which refers to word A. It was necessary, therefore, to break this chain by creating a new, definitive meaning for each word. Eventually, means such as those used by Austin (q.v.) for PRECIS achieved the same purpose, but by much more complex means than just creating a unique definition of each term. Mooers, however, was probably the first to realize how confusing undefined terminology could be. Early automatic indexers dealt with distinct disciplines and, as long as they did not stray beyond disciplinary boundaries, a quick and dirty keyword approach was satisfactory. The trouble came when attempts were made to make a combined index for two or more distinct disciplines. A number of processes have since been developed, mostly involving tagging of some kind or use of strings. Mooers' solution has rarely been considered seriously and probably would be extremely difficult to apply now because of so much interdisciplinarity. But for a specific, weIl defined field, it is still weIl worth considering. Mooers received training in mathematics and physics from the University of Minnesota and the Massachusetts Institute of Technology. He was the founder of Zator Company, which developed and marketed a coded card information retrieval system, and of Rockford Research, Inc., which engages in research in information science. He is the inventor of the TRAC computer language.

    Im Zuge des Aufbaus des DV-gestützten Verbundes der Bibliotheken der obersten Bundesbehörden in Bonn wurde auch der Thesaurus des Bibliothek des Deutschen Bundestages auf DV übernommen. Diese Automatisierung wurde zum Anlaß genommen, den Thesaurus im Lichte des neuesten Standes der nationalen und internationalen Normung zu überarbeiten. Dabei zeigte es sich, daß die Thesaurusnormung, wie sie in den genannten Normen zum Ausdruck kommt, Lücken in bezug auf die Bedürfnisse eines sozialwissenschaftlichen Thesaurus aufweist. Diese bilden den Schwerpunkt der Ausführungen

    Abstract
    After reviewing some fundamental distinctions in relationships (paradigmatic/sytagmatic, interconceptual/ structural) the author proposes a functional approach for investigating the relationships in thesauri. The comparison between three closely related types of semantic fields (lexical, conceptual, thesaural) shows the specific function of relationships in all of these intellectual tools. In information retrieval the two main functions are location of relevant concepts and search of exhaustivity. a clear distinction of these aims can contribute to solving the difficult problem of the choice of 'related terms'. It is suggested that their usefulness relies upon empirical rather than upon semantic proximity. Some practical propositions are amde for the choice and display of relationships in thesauri

    Abstract
    Connecting and evaluating thesauri is an important task for the systematic development of better information retrieval systems. Connecting thesauri includes not only determining when terms in different thesauri are the same but also determining what kinds of relationships can be transferred from one thesaurus to another. This paper first presents issues in connecting and evaluating thesauri. Various experiments in connecting a particular thesaurus, the Medical Subject Headings, with other medical thesauri are described. In these experiments, similar terms in two thesauri are recognized and then differences in two thesauri are exploited to create more powerful thesauri. Part of the evaluation requires the thesaurus to support automatic indexing and retrieving of documents

    Abstract
    Über eine Schnittstelle zwischen Programmen zur automatischen Indexierung (PRIMUS-IDX) und zur maschinellen Thesaurusverwaltung (INDEX) sollen große Textmengen schnell, kostengünstig und konsistent erschlossen und verbesserte Recherchemöglichkeiten geschaffen werden. Zielvorstellung ist ein Verfahren, das auf PCs ablauffähig ist und speziell deutschsprachige Texte bearbeiten kann

    Abstract
    The biomedical book collection in the Genetech Library and Information Services was first inventoried and cataloged in 1983 when it totaled about 2000 titles. Cataloging records were retrieved from the OCLC system and used as a basis for cataloging. A year of cataloging produced a list of 1900 subject terms. More than one term describing the same concept often appears on the list, and no hierarchical structure related the terms to one another. As the collection grew, the subject catalog became increasingly inconsistent. To bring consistency to subject cataloging, a thesaurus of biomedical terms was constructed using the list of subject headings as a basis. This thesaurus follows the broad categories of the National Library of Medicine's Medical Subject Headings and, with some exceptions, the Guidelines for the Establishment and Development of Monolingual Thesauri. It has enabled the cataloger in providing greater in-depth subject analysis of materials added to the collection and in consistently assigning subject headings to cataloging record.
