    Abstract
    For years, Mexico has had a distance learning system backed by television-signal-transmitted videos. The change to digital and computer transmission demands organizing the information system and its subject contents through a thesaurus. To prepare the thesaurus, an evaluation of existing thesauri and standards for data exchange was carried out, aimed at retrieving subject contents and scheduling broadcasting. Methodology for evaluating thesauri was proposed, compared with a virtual educational platform and a basic structure for setting up the information system was recommended.

    Abstract
    This paper reports a part of an on-going PhD study on problems related to multicultural social science thesaurus construction in the general frame of information science. The main analysis methods used are discourse analysis and co-word analysis. In theoretical framework the emphasis is on communicative equivalence theories and different aims of thesaurus translation are discussed. Some examples are given how co-word analysis can be used to study contextual equivalence.

    Abstract
    This paper provides a review of the literature related to the application of domain-specific thesauri in the search and retrieval process. Focusing an studies that adopt a user-centred approach, the review presents a survey of the methodologies and results from empirical studies undertaken an the use of thesauri as sources of term selection for query formulation and expansion during the search process. It summarises the ways in which domain-specific thesauri from different disciplines have been used by various types of users and how these tools aid users in the selection of search terms. The review consists of two main sections: first, studies an thesaurus-aided search term selection; and second, studies dealing with query expansion using thesauri. Both sections are illustrated with case studies that have adopted a user-centred approach.

    Abstract
    A thesaurus in the controlled vocabulary environment is a tool designed to support effective infonnation retrieval (IR) by guiding indexers and searchers consistently to choose the same terms for expressing a given concept or combination of concepts. Terms in the thesaurus are linked by relationships of three well-known types: equivalence, hierarchical, and associative. The functions and properties of these three basic types and some subcategories are described, as well as some additional relationship types conunonly found in thesauri. Progressive automation of IR processes and the capability for simultaneous searching of vast networked resources are creating some pressures for change in the categorization and consistency of relationships.

    Abstract
    The present study investigates the ability of a bibliometric based semi-automatic method to select candidate thesaurus terms from citation contexts. The method consists of document co-citation analysis, citation context analysis, and noun phrase parsing. The investigation is carried out within the specialty area of periodontology. The results clearly demonstrate that the method is able to select important candidate thesaurus terms within the chosen specialty area.

    Abstract
    The purpose of this selected bibliography is to introduce issues and problems in relation to thesaurus construction and to present a set of readings that may be used in practical thesaurus design. The concept of thesaurus is discussed, the purpose of the thesaurus and how the concept has evolved over the years according to new IR technologies. Different approaches to thesaurus construction are introduced, and readings dealing with specific problems and developments in the collection, formation and organisation of thesaurus concepts and terms are presented. Primarily manual construction methods are discussed, but the bibliography also refers to research about techniques for automatic thesaurus construction.

    Abstract
    After a period of experiment and evolution in the 1950s and 1960s, a fairly standard format for thesauri was established with the publication of the influential Thesaurus of Engineering and Scientific Terms (TEST) in 1967. This and other early thesauri relied primarily an the presentation of terms in alphabetical order. The value of a classified presentation was subsequently realised, and in particular the technique of facet analysis has profoundly influenced thesaurus evolution. Thesaurofacet and the Art & Architecture Thesaurus have acted as models for two distinct breeds of thesaurus using faceted displays of terms. As of the 1990s, the expansion of end-user access to vast networked resources is imposing further requirements an the style and structure of controlled vocabularies. The international standards for thesauri, first conceived in a print-based era, are badly in need of updating. Work is in hand in the UK and the USA to revise and develop standards in support of electronic thesauri.

    Abstract
    This paper describes the Laurin thesaurus, which is used for indexing and searching in the Laurin system, a software package for digital clipping archives. As a multilingual thesaurus it complies with the corresponding standards, though presenting some approaches going beyond some of the standards' recommendations. The Laurin thesaurus integrates all kind of indexing terms, not only keywords, but proper names as well. The system of categories and relationships is described in detail.

    Abstract
    This paper describes a method for converting existing thesauri and related resources from their native format to RDF(S) and OWL. The method identifies four steps in the conversion process. In each step, decisions have to be taken with respect to the syntax or semantics of the resulting representation. Each step is supported through a number of guidelines. The method is illustrated through conversions of two large thesauri: MeSH and WordNet.

    Abstract
    Der Thesaurus als Dokumentationssprache wird in der DIN 1463-1in seinen wesentlichen Merkmalen beschrieben. Dort wird der Thesaurus im informationswissenschaftlichen Sinne so definiert: "Ein Thesaurus im Bereich der Information und Dokumentation ist eine geordnete Zusammenstellung von Begriffen und ihren (vorwiegend natürlichsprachigen) Bezeichnungen, die in einem Dokumentationsgebiet zum Indexieren, Speichern und Wiederauffinden dient. Er ist durch folgende Merkmale gekennzeichnet: a) Begriffe und Bezeichnungen werden eindeutig aufeinander bezogen ("terminologische Kontrolle"), indem - Synonyme möglichst vollständig erfasst werden, - Homonyme und Polyseme besonders gekennzeichnet werden, - für jeden Begriff eine Bezeichnung (Vorzugsbenennung, Begriffsnummer oder Notation) festgelegt wird, die den Begriff eindeutig vertritt, b) Beziehungen zwischen Begriffen (repräsentiert durch ihre Bezeichnungen) werden dargestellt." Diese Definition wäre zu ergänzen um folgende: c) Der Thesaurus ist präskriptiv, indem er für seinen Geltungsbereich festlegt, welche begrifflichen Einheiten zur Verfügung gestellt werden und durch welche Bezeichnungen diese repräsentiert werden. Im Folgenden sollen die wichtigsten Elemente und Prinzipien von Thesauri und die Thesaurusmethodik vorgestellt werden. Dies kann in diesem Rahmen nur auf eine sehr kursorische und allgemeine Art und Weise geschehen. Außerdem beschränkt sich die Darstellung auf den Thesauruseinsatz im klassischen Bereich von Information und Dokumentation. Auf die Behandlung von Spezialproblemen oder auf besondere Thesaurusformen (z.B. mehrsprachige Thesauri) kann hier nicht eingegangen werden, ebenso auf die erweiterten Anforderungen, die an Thesauri im Kontext von Wissensrepräsentation oder Hypertext zu stellen sind. Allerdings überschneidet sich der klassische IuD-Bereich zunehmend mit erweiterten Formen (etwa im Rahmen von Internetanwendungen). Da der Thesaurus im dokumentarischen Sinn alle Grundelemente des Thesaurusprinzips in klarer Form aufweist, wird dieser Bereich für eine Einführung gewählt. Für eine intensivere Auseinandersetzung mit der Thematik wird die Lektüre von Wersig empfohlen, auf den sich auch die folgenden Ausführungen in weiten Teilen stützen. Eine weitere grundsätzliche Einführung in diesen Bereich, allerdings eher ausgerichtet auf die Spezifika des englischen Sprachraums, findet sich bei Lancaster.

    Abstract
    Thesauri can be useful resources for indexing and retrieval on the Semantic Web, but often they are not published in RDF/OWL. To convert thesauri to RDF for use in Semantic Web applications and to ensure the quality and utility of the conversion a structured method is required. Moreover, if different thesauri are to be interoperable without complicated mappings, a standard schema for thesauri is required. This paper presents a method for conversion of thesauri to the SKOS RDF/OWL schema, which is a proposal for such a standard under development by W3Cs Semantic Web Best Practices Working Group. We apply the method to three thesauri: IPSV, GTAA and MeSH. With these case studies we evaluate our method and the applicability of SKOS for representing thesauri.

    Abstract
    This paper presents an overview of the work in progress at the W3C to produce a standard conversion of WordNet to the RDF/OWL representation language in use in the SemanticWeb community. Such a standard representation is useful to provide application developers a high-quality resource and to promote interoperability. Important requirements in this conversion process are that it should be complete and should stay close to WordNet's conceptual model. The paper explains the steps taken to produce the conversion and details design decisions such as the composition of the class hierarchy and properties, the addition of suitable OWL semantics and the chosen format of the URIs. Additional topics include a strategy to incorporate OWL and RDFS semantics in one schema such that both RDF(S) infrastructure and OWL infrastructure can interpret the information correctly, problems encountered in understanding the Prolog source files and the description of the two versions that are provided (Basic and Full) to accommodate different usages of WordNet.
