    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
    Open system protocols for search and retrieval have not provided explicit ways in which to implement thesaurus-aided searching. A number of different approaches within the existing protocols, as well as a proposed service, are evaluated. A general approach to implementing thesaurus-aided searching, particularly during consultation of a thesaurus, requires an entirely new service, whose main features are described

    Abstract
    Once the library has been through a process of transition from traditional library procedures to automated ones, natural language searching became a necessity for both indexers and searchers. Therefore, aside from the precoordinated classified catalogue we started to build a dictionary of terms in order to make postcoordinate search possible in keeping with the UDC notations assigned to each bibliographic record. After a while we came to the conclusion that the dictionary needed a control of its terms so that synonymous concepts and semantic ambuguities be avoided. The project presented in this paper shows how reality imposed the improvement of the quality of indexing and hence of the searching possibilities. Is also shows the reasons why we consider a multilingual thesaurus based on UDC an ideal indexing and searching device. The experiment applied on class 8 of UDC illustrates the way the UDC tables can be quite successfully used in building a thesaurus due to their qulities and how their limitations can be overcome by a thesaurus. An appendix to the paper contains a sample of the multilingual thesaurus given in both alphabetical and systematic layouts

    Abstract
    For more than thirty years thesauri have been valuable tools in information retrieval. Originally, the basic function of the thesauri was to help the indexer to transform concepts and their relationships, as expressed in the language of documents, into the more regularised indexing language of catalogues and databases. In the nineties another important purpose of the thesauri is to guide the searcher to the best search terms. In spite of the new role, the design of the thesauri has remained more or less stable. This paper explores the demands which are put on the thesauri in relation to searching. Findings are presented in the form of generalisations and moreover illustrated in relation to a real-life situation. Suggestions for improved functionality are presented in the form of a prototype of a thesaurus record. The new role as a conceptual searching tool is also influencing the construction process. Therefore, the paper ends up with a discussion of new methods for thesaurus construction

    Abstract
    While information retrieval thesauri may improve search results, there is little research documenting whether general information system users employ these vocabulary tools. This article explores user comprehension and searching with thesauri. Data was gathered as part of a larger empirical query-expansion study involving the ProQuest Controlled Vocabulary. The results suggest that users' knowledge of thesauri is extremely limited. After receiving a basic thesaurus introduction, however, users indicate a desire to employ these tools. The most significant result was that users expressed a preference for thesauri employment through interactive processing or a combination of automatic and interactive processing, compared to exclusively automatic processing. This article defines information retrieval thesauri, summarizes research results, considers circumstances underlying users' knowledge and searching with thesauri, and highlights future research needs.

    Abstract
    The basic elements of faceted thesauri are described, together with a review of their origins and some prominent examples. Their use in browsing and searching applications is discussed. Faceted thesauri are distinguished from faceted classification schemes, while acknowledging the close similarities. The paper concludes by comparing faceted thesauri and related knowledge organization systems to ontologies and discussing appropriate areas of use.

    Abstract
    When consumers search for health information, a major obstacle is their unfamiliarity with the medical terminology. Even though medical thesauri such as the Medical Subject Headings (MeSH) and related tools (e.g., the MeSH Browser) were created to help consumers find medical term definitions, the lack of direct and explicit integration of these help tools into a health retrieval system prevented them from effectively achieving their objectives. To explore this issue, we conducted an empirical study with two systems: One is a simple interface system supporting query-based searching; the other is an augmented system with two new components supporting MeSH term searching and MeSH tree browsing. A total of 45 subjects were recruited to participate in the study. The results indicated that the augmented system is more effective than the simple system in terms of improving user-perceived topic familiarity and question-answer performance, even though we did not find users spend more time on the augmented system. The two new MeSH help components played a critical role in participants' health information retrieval and were found to allow them to develop new search strategies. The findings of the study enhanced our understanding of consumers' search behaviors and shed light on the design of future health information retrieval systems.

    Abstract
    Part of a special issue on hypertext and information retrieval. Conventional information retrieval systems provide little support for browsing. Browsing is the major method of searching in hypertext system but users can become disoriented even when browsing small information space. If hypertext is to be used to support browsing in bibliographic databases navigational assistance will be required. Examines the role of thesauri as navigational aids for subject domains of Bibliographic databases. Presents the design of an experimental hypertext-based browsing inference for a thesaurus and its implementation using a commercially available hypertext program. Examines strategies for linking the thesaurus to a database

    Abstract
    The derivation of a thesaurus from a new schedule for UDC class 61 Medical Sciences which has been restructured into a faceted classification system using the framework provided by the Bliss Bibliographic Classification. The resulting thesaurus is intended to serve as a tool for indexing and searching but will also be the index to the 61 class itself. The background for the research is briefly described.

    Abstract
    Discusses the concept of descriptor equivalence, with its 2 subcomponents of dictionary equivalence and indexing equivalence, in the context of the compatibility of differnt thesauri used in bilingual indexing. In multilingual indexing and searching, the equivalence relationship between terms means either that all equal terms are descriptors or that only one of the terms is selected for the descriptor and users are directed with USE refrences to use it instead of the other potential terms. Discusses these issues with particular reference to the LUASPORT study: a study of the compatibility of the Finnish language sports thesaurus (LUAS) with the Canadian Sport Thesauri (SPORT) in terms of compatibility of subject descriptors. In LUASPORT, LUAS was the source thesaurus and SPORT was the target thesaurus

    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
    Until the 1980s, concepts like authority control, controlled vocabularies, and metadata and schemas were all but unknown in the world of art and material culture information. This paper traces the evolution and current status of tools and resources for authority control of art information, and gives examples of how the lack of authority control can impede end-user access. Collection-specific thesauri and subject indexes, and vocabulary-assisted searching and query expansion are also discussed.

    Abstract
    This article provides an overview of recent developments relating to the application of thesauri in information organisation and retrieval on the World Wide Web. It describes some recent thesaurus projects undertaken to facilitate resource description and discovery and access to wide-ranging information resources on the Internet. Types of thesauri available on the Web, thesauri integrated in databases and information retrieval systems, and multiple-thesaurus systems for cross-database searching are also discussed. Collective efforts and events in addressing the standardisation and novel applications of thesauri are briefly reviewed.

    Abstract
    An approach to accessing databases, which makes extensive use of structured thesaurus views for presenting and searching a large bibliographic database through progressive refinement, is being investigated in a research project which is seeking to apply usability criteria as the determinant for interface design. It aims to investigate measurements of retrieval performance in an application of graphical user interface techniques using multi-windowed layered attribute value aggregation, including those provided by a structured thesaurus, to access bibliographic databases. This paper reports on the progress made in the first year of the project of the application of usability methodologies, the revision of a preliminray design and the resulting prototype development. Implications for more widespread applications are discussed

    Abstract
    In this paper, after an introduction about problems of multilingual information languages, the rules and recommendations of the Guidelines for the establishment and development of multilingual thesauri for non-equivalence and partial equivalence of terms in different languages are discussed. Artificial terms are not very useful in searching, because most users are not willing to use a thesaurus to find the right descriptor. On the other hand indexers need guidance on how to index and therefore need a thesaurus with all desirable and necessary relations. It is suggested that bibliographic online systems can take over some of the functions for the searcher from the thesaurus and that a few new relations could be helpful to an indexer

    Abstract
    In the UK, the aim to make public sector information much more available to the citizen has led to establishment of an "e-Govemment Interoperability Framework" based an a set of core standards. Among the standards is a controlled vocabulary, known as the Govemment Category List (GCL), used to select keywords for the metadata of all electronic resources originating from central or local govemment. The GCL is a small and simple taxonomy, designed to facilitate high-level browsing rather than deep searching. Specialized thesauri for particular subject areas may optionally complement the GCL. To ease the indexing burden, GCL terms will often be selected by direct mapping from the specialized vocabularies.
