    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
    The Art and Architecture Thesaurus (AAT) was designed as a comprehensive vocabulary in its domain. Its faceted, hierarchically arranged structure allows for powerful indexing and retrieval capabilities, while its planned network of related term relationships makes it especially amenable to natural language processing. To gauge the AAT's effectiveness as a search tool against natural language queries, an experiment was carried out on DIALOG. There are 3 art data bases on DIALOG and there are also a number of other data bases that contain art related material. The experiment used queries culled from reference librarians at art and architecture libraries.

    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
    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
    An attempt is made to compare the existing standards and guidelines for thesaurus consruction and development, focussing particularly on the ISO, BSI standards as well as on the guidelines suggested by Aitchison and Gilchrist, and UNISIST. The different facets/aspects considered are: linguistic aspects of thesauri; formal requirements suggested by the standards/guidelines with special emphasis on problems associated with the compound terms, homographs, forms of terms, etc.; semantic relationships between terms - synonymy, BT/NT, and associativity; problems peculiar to multilingual thesauri, especially the problem of inexact equivalence between terms; and presentation and arrangement of terms in a thesaurus

    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
