    Abstract
    Describes a design for ideal online subject and author thesauri. The subject thesaurus is a graphic thesaurus with a semantic network, so the spread activation assumption can be applied. The hierarchical relationship is broken into 3 specific relations, so automated inheritance can be performed. The associated relationship is separated with several specific relationships, so spatial recognition can function well. This thesaurus will provide variety and complexity to deal with uncertainty and will be a user constructed, user enhanced hyperthesaurus that serves as an analogue of the human mind. The author thesaurus is designed to show all authors which are alphabetically adjacent to a given author as well as other authors whose subject area is close to that of the given author

    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
    Presents a state of the art review of the literature of expert systems in library and information science, involving exhaustive searches of all major LIS CD-ROM databases (LISA, ERIC, LiLi, INSPEC etc.) and bibliographies appended in review articles. The search retrieved 679 references, comprising 362 periodical articles, 180 conference proceedings, 63 books articles, 28 theses and 46 monographs. The growth of the literature peaked between 1989 and 1990 and subsequently declined after 1992. Over 1/3 (287) covered intelligent front ends and interfaces for online searching and retrieval, followed by applications in reference service (113), classification, indexing and abstracting (86) and cataloguing (7). The most productive periodicals comprised 6 titles, of which 'Information processing and management' topped the lsit: 43 authors were found to contribute between 5 and 35 articles each, hence contributing 32,19% of the total contributors. 382 of the publications were single author works, 172 were by 2 authors, 72 were by 3 authors and 49 were by 4 or more authors. Only 161 titles were expressive enough to reveal both the name and function of systems being developed

    Abstract
    The patterns of overlap between terms which are closely related in a thesaurus are considered. The relationships considered are parent/child, in which one term is a broader term of the other, and sibling in which to 2 terms share the same broader term. The patterns of overlap observed in the MeSH thesaurus with respect to selected MEDLINE postings are examined. The implications of the overlap patterns are discussed, in particular, the impact of the overlap patterns on the potential effectiveness of a proposed algorithm for handling negation is considered.

    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
    In the 21st century, multilingual tools are gaining importance as increasingly diverse user groups from different cultural and linguistic backgrounds seek access to equally diverse pieces of information. The authors of this paper believe that most current forms of multilingual information access are inadequate for this role, and that a new form of multilingual thesaurus is required. The core of this paper introduces their pilot thesaurus InfoDEFT as a possible model for new online thesauri, which are semantically structured, encyclopedic and multilingual. The authors conclude that while the manual construction of such thesauri is labour intensive and hence costly, pilot thesauri can be used as training sets for artificial learning programmes, thus increasing their volume considerably at relatively little extra cost.
