    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
    The information retrieval problem is described starting from an analysis of the concepts 'user's information request' and 'information offerings of texts'. It is shown that natural language phrases are a more adequate medium for expressing information requests and information offerings than character string based query and indexing languages complemented by Boolean oprators. The phrases must be represented as concepts to reach a language invariant level for rule based relevance analysis. The special type of representation called advanced thesaurus is used for the semantic representation of natural language phrases and for relevance processing. The analysis of the retrieval problem leads to a symmetric system structure

    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 Electronic Libraries and Information Highways MITRE Sponsored Research project aims to help searchers working in digital libraries increase their chance of matching the language of authors. Focuses on whether query formulation can be improved through the addition of semantic knowledge that is interactively gathered from a thesaurus that exists in a distributed, interoperating, cooperative environment. A prototype, ELVIS, was built that improves information retrieval through query expansion and is based on publicly available Z39.50 standard thesauri integrated with networked information discovery and retrieval tools

    Abstract
    Describes the backgroud to the construction of a thesaurus at Hydro-Quebec, Quebec, Canada. Several information units, linked to form a network, share the same bibliographic database. The need for coherence and efficiency was the principle motive for the construction of the multidisciplinary thesaurus. Describes the construction process, discusses the specifity of the tool, its circulation, and considers its use on a partnership basis with other information services

    Abstract
    Reports on the development of a thesaurus by Engineering Information, Inc. for use in indexing its databases. The concept in the former, highly precoordinate, indexing vocabulary were converted into postcoodinate descriptors, and a full set of thesaural relationships developed. Issues to be resolved in developing the vocabulary included the degree of postcoordination that was appropriate, the need to make the thesaurus usable with retrospective indexing that could not be converted and the demands on in-house staff during the development and conversion process

    Abstract
    Although commonly used in both commercial and experimental information retrieval systems, thesauri have not demonstrated consistent benefits for retrieval performance, and it is difficult to construct a thesaurus automatically for large text databases. In this paper, an approach, called PhraseFinder, is proposed to construct collection-dependent association thesauri automatically using large full-text document collections. The association thesaurus can be accessed through natural language queries in INQUERY, an information retrieval system based on the probabilistic inference network. Experiments are conducted in INQUERY to evaluate different types of association thesauri, and thesauri constructed for a variety of collections

    Abstract
    Shows that it is possible to construct a lexical database by combining material from a number of machine-readable sources. Discusses the kind of lexical information required for applications in information retrieval and in other natural language processing areas, such as database interfaces and automatic filing systems. Describes the organization of the lexical database which is stored in an Oracle relational database management system and the design of the tables that comprise the database. In addition to the traditional alphabetic listing, access is privided from roots to derived forms and from derived forms to roots, and also through lexical and semantic relations between words, so that the database functions as a thesaurus as well as a dictionary. The database is designed to be open-ended and self-defined. Every attribute of every table is defined in the database itself. The lexical database can easily be extended through an SQL forms interface that facilitates additions to the tables
