    Abstract
    The application of thesauri in networked environments is seriously hampered by the challenges of introducing new concepts and terminology into the formal controlled vocabulary, which is critical for enhancing its retrieval capability. The author describes an automated process of adding new terms to thesauri as entry vocabulary by analyzing the association between words/phrases extracted from bibliographic titles and subject descriptors in the metadata record (subject descriptors are terms assigned from controlled vocabularies of thesauri to describe the subjects of the objects [e.g., books, articles] represented by the metadata records). The investigated approach uses a corpus of metadata for scientific and technical (S&T) publications in which the titles contain substantive words for key topics. The three steps of the method are (a) extracting words and phrases from the title field of the metadata; (b) applying a method to identify and select the specific and meaningful keywords based on the associated controlled vocabulary terms from the thesaurus used to catalog the objects; and (c) inserting selected keywords into the thesaurus as new terms (most of them are in hierarchical relationships with the existing concepts), thereby updating the thesaurus with new terminology that is being used in the literature. The effectiveness of the method was demonstrated by an experiment with the Chinese Classification Thesaurus (CCT) and bibliographic data in China Machine-Readable Cataloging Record (MARC) format (CNMARC) provided by Peking University Library. This approach is equally effective in large-scale collections and in other languages.

    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
    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
    The Nuovo soggettario, the official Italian subject indexing system edited by the National Central Library of Florence, is made up of interactive components, the core of which is a general thesaurus and some rules of a conventional syntax for subject string construction. The Nuovo soggettario Thesaurus is in compliance with ISO 25964: 2011-2013, IFLA LRM, and FAIR principle (findability, accessibility, interoperability, and reusability). Its open data are available in the Zthes, MARC21, and in SKOS formats and allow for interoperability with l library, archive, and museum databases. The Thesaurus's macrostructure is organized into four fundamental macro-categories, thirteen categories, and facets. The facets allow for the orderly development of hierarchies, thereby limiting polyhierarchies and promoting the grouping of homogenous concepts. This paper addresses the main features and peculiarities which have characterized the consistent development of this categorical structure and its effects on the syntactic sphere in a predominantly pre-coordinated usage context.

    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
    Describes a deductive data model based on 3 abstraction levels for representing vocabularies for information retrieval: conceptual level; expression level; and occurrence level. The proposed data model can be used for the representation and navigation of indexing and retrieval thesauri and as a vocabulary source for concept based query expansion in heterogeneous retrieval environments

    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
    Although thesauri can be solve some problems posed by computerised data base searching (synonyms, generic representation) their compilation requires extensive time and effort of experts and their maintenance is also difficult. Describes how a thesaurus was compiled and maintained automatically by taking advantage of the specially designed formats to input expertise with ease. The thesaurus was named a dynamic thesaurus because it depends on the set of stored data and is adapted to the necessary and sufficient range of keywords. A data base of polymers is taken as an example.

    Abstract
    This document describes in brief how to express the content and structure of a thesaurus, and metadata about a thesaurus, in RDF. Using RDF allows data to be linked to and/or merged with other RDF data by semantic web applications. The Semantic Web, which is based on the Resource Description Framework (RDF), provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries.

    Abstract
    Efforts towards internationalization have become increasingly important in scientific environments. As for content-based indexing of scientific research data, however, standards leading to internationally coherent indexing which is vital for retrieval purposes are not yet sufficiently developed. Even concerning the concrete use of indexing instruments, launched by initiatives on an international scale, there are still no binding policies and guidelines. Against this backdrop, essential criteria which internationally applicable indexing systems should meet will be outlined. These will be illustrated through the multilingual European Language Social Science Thesaurus (ELSST), originally based on the UK Data Archive's (UKDA) Humanities and Social Science Electronic Thesaurus (HASSET) and ultimately developed by the Council of European Social Science Data Archives (CESSDA). Additionally, the general pros and cons of using international versus national indexing languages will be weighed using the ELSST and the Thesaurus for the Social Sciences (TSS) developed by GESIS - Leibniz-Institute for the Social Sciences. In this light, the benefit of vocabulary crosswalks for supporting a combined use of international and national indexing systems will be discussed.
