    Abstract
    Bericht über die Ergebnisse einer von der Kommission der Europäischen Gemeinschaften in Brüssel vom 11.12.3.86 organisierten Konferenz. Als Ausgangspunkte dienten Folgerungen aus einer umfassenden Analyse von fast 1.000 Thesauri, dahingehemd, daß 'too many thesauri hampered by inadequate design, inappropriate exploitation, sometimes even non-use, insufficient maintenance, and inadequate development and updating software'. Die Ziele der Konferenz waren: (1) Set up an inventory of problems encountered in compiling, using, and managing a thesaurus; (2) Measure the impact of these problems on the effectiveness of information retrieval; (3) Make recommendations in order to solve these problems or avoid their occurrence

    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
    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
    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.

    Abstract
    Although thesauri can be solve some problems posed by computerised data base searching (synonyms, generic representation) their compilation requires extensive time and effort of experts and their maintenance is also difficult. Describes how a thesaurus was compiled and maintained automatically by taking advantage of the specially designed formats to input expertise with ease. The thesaurus was named a dynamic thesaurus because it depends on the set of stored data and is adapted to the necessary and sufficient range of keywords. A data base of polymers is taken as an example.
