    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
    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
    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
    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
