    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 benefits of a well constructed thesaurus to an information retrieval system have long been recognised by both researchers and practitioners in the field. Examines both early and current approaches to automatic thesaurus construction and describes an approach to the automatic generation of global thesauri based on the term discrimination value model of Salton Yang, and Yu and on an appropriate clustering algorithm. This method has been implemented and applied to 2 document collections. Preliminary results indicate that this method, which produces improvements in retrieval performance in excess of 10 and 15% in the test collections, is viable and worthy of continued investigation.

    Abstract
    This paper describes a proposal for a new approach to thesaurus design and construction that could have significant implicantions for change in the way multilingual thesauri are handled and integrated with each other. The formula presented here has its origin in the work of the German Thesaurus Committee and has had input from a number of scientists and practitioners int he field. The emphasis is on the various types of relationships found among concepts, notiions and universals in languages. These relationships are analysed and refined beyond the approach taken in existing thesauri. This proposal is very much at the discussion stage and the author invites the assistance of interested readers through criticisms, discussion and dialogue. Applications of the proposed thesaurus are included and the major goal of this proposal is to provide the basis for improved desing and integration of multilingual thesauri

    Abstract
    Despite early claims to the contemporary, thesauri continue to find use as access tools for information in the full-text environment. Their mode of use is changing, but this change actually represents an expansion rather than a contrdiction of their utility. Thesauri and similar vocabulary tools can complement full-text access by aiding users in focusing their searches, by supplementing the linguistic analysis of the text search engine, and even by serving as one of the tools used by the linguistic engine for its analysis. While human indexing contunues to be used for many databases, the trend is to increase the use of machine aids for this purpose. All machine-aided indexing (MAI) systems rely on thesauri as the basis for term selection. In the 21st century, the balance of effort between human and machine will change at both input and output, but thesauri will continue to play an important role for the foreseeable future

    Abstract
    Describes a specific application of domain analysis to the construction of thesauri to exploit domain analysis' ability to construct valid domain representations and determine fuzzy limits that normally define specific domains. The system employs a structure, called a Software Thesaurus (developed from a descriptor thesaurus), as a repository to store the information regarding specific domains. The domain representation is constructued semi automatically and can be used as a means of semiautomatic thesaurus generation

    Abstract
    In 1987 the Department of Library and Information Science at the University of South Africa committed itself to a research programme on community information. As part of that programme, the Department's Centre for Library and Information Service is compiling a prototype resource file of community information for a well-defined community in the Pretoria municipality. To retrieve information from the file, the Centre adopted an alphabetical approach, which necessitated a thesaurus. Instead of developing a thesaurus for the specific needs of the particular community, a "master" thesaurus, applicable to South African communities can be generated. The development of this South African "master" thesaurus for community information is described and the results reviewed.

    Abstract
    A metathesaurus is a set made of a reference thesaurus and various forms of indexing languages attached to it. Among these, the sub-thesauri cover restricted fields in more detail. A functional definition of the sub-thesaurus is proposed: elements, relationships, sub-systems and rules to be respected to preserve the possibilities for communication via the reference thesaurus. Considerations on the methods of presentation, the use and the compilation are also given

    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
    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
    The need for thesauri to help users in their search for information in online information systems has been discussed for several decades. Many wide-ranging contributions have been made to solve this problem. Nevertheless, investigation is needed to design a thesaurus structure based on what is relevant for users and generators of information within a specific subject domain. Explores the possibility of creating a thesaurus from the cognitive viewpoint. This approach is based on a system that organizes its representation of knowledge or its classification as closely as possible to the authors' and users' images of the subject domain with the objective of increasing the interaction between users and texts, and thus the communication in a given information retrieval system. Discourse analysis is used as a main method to identify the categories and its relevance for building such a structure is discussed

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
    Terminological definitions establish relations between terms and concepts by specifying the characteristics of each concept and locating it in the knowledge area. Using results from a largely automatic analysis of standardised (BSI/ISO) definitions, this paper demonstrates that technical definitions are rich in term content and that they contain a number of relations which can be used in the construction of a terminological control device such as a terminological thesaurus. Such a thesaurus will contain the keyconcepts of the domain, and can be used by technical authors to produce texts with greater consistency of terminology
