    Abstract
    Most indexed databases now include their thesauri and/or coding in their bibliographic files, searchable at the databases' online connect rates. Assesses the searchability of these on the different hosts. Thesauri and classifications are also available as diskette or CD-ROM products. Describes a number of these, highlighting the diskette thesaurus from IFI/Plenum Data for its flexible databases, the CLAIMS Uniterm and Comprehensive indexes to US chemical patents

    Abstract
    The Nuovo soggettario, the official Italian subject indexing system edited by the National Central Library of Florence, is made up of interactive components, the core of which is a general thesaurus and some rules of a conventional syntax for subject string construction. The Nuovo soggettario Thesaurus is in compliance with ISO 25964: 2011-2013, IFLA LRM, and FAIR principle (findability, accessibility, interoperability, and reusability). Its open data are available in the Zthes, MARC21, and in SKOS formats and allow for interoperability with l library, archive, and museum databases. The Thesaurus's macrostructure is organized into four fundamental macro-categories, thirteen categories, and facets. The facets allow for the orderly development of hierarchies, thereby limiting polyhierarchies and promoting the grouping of homogenous concepts. This paper addresses the main features and peculiarities which have characterized the consistent development of this categorical structure and its effects on the syntactic sphere in a predominantly pre-coordinated usage context.

    Abstract
    Describes a deductive data model based on 3 abstraction levels for representing vocabularies for information retrieval: conceptual level; expression level; and occurrence level. The proposed data model can be used for the representation and navigation of indexing and retrieval thesauri and as a vocabulary source for concept based query expansion in heterogeneous retrieval environments

    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.

    Abstract
    This document describes in brief how to express the content and structure of a thesaurus, and metadata about a thesaurus, in RDF. Using RDF allows data to be linked to and/or merged with other RDF data by semantic web applications. The Semantic Web, which is based on the Resource Description Framework (RDF), provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries.

    Abstract
    Efforts towards internationalization have become increasingly important in scientific environments. As for content-based indexing of scientific research data, however, standards leading to internationally coherent indexing which is vital for retrieval purposes are not yet sufficiently developed. Even concerning the concrete use of indexing instruments, launched by initiatives on an international scale, there are still no binding policies and guidelines. Against this backdrop, essential criteria which internationally applicable indexing systems should meet will be outlined. These will be illustrated through the multilingual European Language Social Science Thesaurus (ELSST), originally based on the UK Data Archive's (UKDA) Humanities and Social Science Electronic Thesaurus (HASSET) and ultimately developed by the Council of European Social Science Data Archives (CESSDA). Additionally, the general pros and cons of using international versus national indexing languages will be weighed using the ELSST and the Thesaurus for the Social Sciences (TSS) developed by GESIS - Leibniz-Institute for the Social Sciences. In this light, the benefit of vocabulary crosswalks for supporting a combined use of international and national indexing systems will be discussed.

    "Das Informationsnetz zwischen dem österreichischen und dem deutschen Umweltbundesamt wird enger. Nach dem gemeinsam entwickelten Umweltthesaurus für die Umweltdatenkataloge (UDK-Thesaurus) erscheint nun "THESshow", eine CD-ROM mit mehrsprachigen umwelt-relevanten Fachbegriffen (Thesauri und Glossare). Sie ermöglicht eine raschere Suche nach Dokumenten und Informationen und ist auch für Aufbau und Pflege von Bibliotheks- und anderen Informationssystemen geeignet. Vergleichbar mit einem Wörterbuch, helfen Thesauri, Dokumentationssysteme nach festgelegten Stichwörtern inhaltlich zu ordnen. "THESshow" beinhaltet unter anderem: UDK-Thesaurus Version 6, GEMET (General Multilingual Environment Thesaurus) mit 19 Sprachen, ENVOC (Multilingual Thesaurus of Environmental Terms, UNEP/INFOTERRA) mit vier UN-Sprachen, das Abfallwirtschaftsglossar des Österreichischen Normungsinstituts mit neun Sprachen, sowie das "Lexikon Waldschädigende Luftverunreinigungen" des Bundesamtes und Forschungszentrums für Wald (BFW). In einer Kooperation der Umweltbundesämter mit dem italienischen Consiglio Nazionale delle Ricerche (CNR), Rom, entstand zudem das Produkt "SuperThes" zur Wartung und Pflege multilingualer Thesauri nach den Normen DIN 1462 / ISO 2788 und DIN / ISO 5964. Sowohl "THESshow" als auch "SuperThes" können an kundenspezifische Anforderungen angepasst werden."

    Abstract
    Automatic thesaurus construction is accomplished by extracting term relations mechanically. A popular method uses statistical analysis to discover the term relations. For low frequency terms the statistical information of the terms cannot be reliably used for deciding the relationship of terms. This problem is referred to as the data sparseness problem. Many studies have shown that low frequency terms are of most use in thesaurus construction. Characterizes the statistical behaviour of terms by using an inference network. Develops a formal approach using a Baysian network for the data sparseness problem

    Abstract
    Design and construction of indexing languages require thorough knowledge and understanding of the information environment. This empirical study investigated a mixed set of methods (group interviews, recollection of information needs and word association tests to collect data; content analysis and discourse analysis to analyse data) to evaluate whether these methods collected the data needed for work domain oriented thesaurus design. The findings showed that the study methods together provided the domain knowledge needed to define the role of the thesaurus and design its content and structure. The study was carried out from a person-insituation perspective. The findings reflected the information environment and made it possible to develop a thesaurus according to the characteristics of the work domain. It seemed more difficult to capture the needs of the individual user and adapt the thesaurus to individual characteristics.

    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
    This paper describes the procedures for a concept-based mapping of two agricultural thesauri, the multilingual AGROVOC, created and maintained by the Food and Agricultural Organization, and the bilingual Chinese Agricultural Thesaurus, created and maintained by the Chinese Academy of Agricultural Science. Conducted under the auspices of FAO's Agricultural Ontology Service, the mapping project aims to extend AGROVOC with an additional set of perspectives on the agricultural domains, enrich its domain and language coverage, and make use of AGROVOC as a common data model for data exchange among a wide range of multilingual repositories within agriculture.

    Abstract
    This paper demonstrates the application of conventional database design techniques to thesaurus representation. The thesaurus is considered as a printed document, as a semantic net, and as a relational database to be used in conjunction with an intelligent information retrieval system. Some issues raised by analysis of two standard thesauri include: the prevalence of compound terms and the representation of term structure; thesaurus redundancy and the extent to which it can be eliminated in machine-readable versions; the difficulty of exploiting thesaurus knowledge originally designed for human rather than automatic interpretation; deriving 'strength of association' measures between terms in a thesaurus considered as a semantic net; facet representation and the need for variations in the data model to cater for structural differences between thesauri. A complete schema of database tables is presented, with an outline suggestion for using the stored information when matching one or more thesaurus terms with a user's query

    Abstract
    Five years ago, we raised the question: is there a data model which is general enough such that all existing thesauri can be represented by a specialization of this general model without loss of information? The answer was not given at that time, but we referred to the principle of abstraction, well supported in object-oriented data modelling. We gained the empirical basis for that process of abstraction by modelling existing thesauri and a terminological dictionary; an abstracting view was afterwards presented in a paper to the TKE'93 conference. The present paper reports on a third step of abstraction with its very concrete consequences, embodies in a software called TerminologyFramework(TFw)
