    Abstract
    Specifications are presented for software designed to support manual development and maintenance of information retrieval thesauri. The specifications are intended to support both evaluation of existing packages for acquisition and design of custom software. Specialized requirements of thesaurus support are emphasized over more general database management requirements. Requirements for integration with larger systems and for the user interface are summarized. Relationships specified by the ANSI standard should be supported, and the relationships should be validated to avoid introduction of conflicting relationships. Flexibility in availability of note and date fields is important, and where required, term classifications should be available. Maintenance procedures should include provision for feedback on the impact of changes, as well as appropriate levels of approval for changes. A wide variety of online displays and printed reports are required, including but not limited to alphabetical, hierarchical, and rotated. In addition, it is desirable to be absle to search the thesaurus database with such capabilities as Boolean logic and proximity operators

    Abstract
    Describes a consultancy project for the development of a health care thesaurus involving the movement of text between different application programs. The thesaurus was built from existing text within the organisation originating from 3 sources: natural language registry file headings; descriptions from an internal business directory and a controlled vocabulary. The software used was WordPerfect and Cardbox

    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
    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

    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 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
    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
    Five years ago, we raised the question: is there a data model which is general enough such that all existing thesauri can be represented by a specialization of this general model without loss of information? The answer was not given at that time, but we referred to the principle of abstraction, well supported in object-oriented data modelling. We gained the empirical basis for that process of abstraction by modelling existing thesauri and a terminological dictionary; an abstracting view was afterwards presented in a paper to the TKE'93 conference. The present paper reports on a third step of abstraction with its very concrete consequences, embodies in a software called TerminologyFramework(TFw)

    Abstract
    This article introduces a new concept and technique for information retrieval called 'colinked descriptors'. Borrowed from an analogous idea in bibliometrics - cocited references - colinked descriptors provide a theory and method for identifying search terms that, by hypothesis, will be superior to those entered initially by a searcher. The theory suggests a means of moving automatically from 2 or more initial search terms, to other terms that should be superior in retrieval performance to the 2 original terms. A research project designed to test this colinked descriptor hypothesis is reported. The results suggest that the approach is effective, although methodological problems in testing the idea are reported. Algorithms to generate colinked descriptors can be incorporated easily into system interfaces, front-end or pre-search systems, or help software, in any database that employs a thesaurus. The potential use of colinked descriptors is a strong argument for building richer and more complex thesauri that reflect as many legitimate links among descriptors as possible

    Abstract
    Discusses the various functions which a thesaurus can have. Highlights the main function of a thesaurus in vocabulary control, eliminating natural language ambiguity and providing consistency of indexing, and serving as an aid in the searching process. Further discusses the function of a search thesaurus in serving as a user's aid in full text systems and in free indexing systems, and the additional function of an online thesaurus integrated with an online database, that of a vocabulary master file. Notes also how a thesaurus can function as a switching language or intermediary lexicon in multidatabase systems

    Abstract
    The ISO 2788 guidelines for monolingual thesauri contain a differentiation of "the hierarchical relationship" into "generic", "partitive", and "instance", which, for purposes of document retrieval, was deemed adequate. However, ontologies, designed as language inventories for a wider scope of knowledge representation, are based on all these and some more logical differentiations. Rereading the ISO 2788 standard and inspecting the published Cyc Upper Ontology, it is argued that the adoption of the document-retrieval definition of subsumption generally prevents the conception or use of a thesaurus as a substructure of an ontology of the new kind as constructed for AI applications. When a thesaurus is used for fact description and inference on fact descriptions, the instance-of relationship too should be reconsidered: It may also link concepts and metaconcepts, and then its distinction from subsumption is needed. The treatment of the instance-of relationship in thesauri, the Cyc Upper Ontology, and WordNet is described from this perspective

    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
    The ageing of the world population has focused attention on both geriatrics and gerontology and the past few years have seen the emergence of a holistic approach to serving the needs of elderly people. This has resulted in a need to harmonize the terminology of both domains. Reports developments in the creation of a bilingual controlled vocabulary in gerontology and geriatrics, a project undertaken jointly by the Graduate School of Library and Information Studies at McGill University and the Centre hospitalier Côte-des-Neiges in Quebec focusing on: the definition and purpose of the thesaurus; methodology; the user; communication between the 2 participants; choice of software; and verification of the vocabulary

    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
    Describes the compilation of a subject thesaurus to provide a controlled vocabulary for indexing the New South Wales Government Printing Office's collection of historical photographs. Discusses the use of interactive videodiscs for preserving, presenting and retrieving pictorial collections and describes the software, online access, and data entry. Considers the development of the subject thesaurus and outlines 3 approaches that might be used by institutions faced with describing and indexing a collection of photographs. Discusses some possible authorities for subject analysis of pictorial materials. Describes the building process focusing on compilation and maintenance, classes excluded, strucutre of the thesaurus and the question of publication
