    Abstract
    Describes CLASTHES, a software package which structures a system of concepts defined both as the conceptual expression of the structural relationship of a whole and as the structural relationship between the individual elements within the system itself. The external structure, which is the general structure of the system, is created by means of thesaurus facets, here defined as 'areas', while the internal structure is represented by the relationships linking the single elements attributed to the various areas

    Abstract
    The case under consideration is a project of building an interdisciplinary multilingual thesaurus (Romanian-English-French) starting from a list of indexing terms based on an abridged version of the Universal Decimal Classification (UDC). The resulting thesaurus is intended for public libraries for both indexing and searching purposes in bibliographic databases covering a wide range of topics but with a fairly low level of specificity. The problems encountered in such an approach fall into two groups: 1) concordance or compatibility problems in terms of the indexing languages considered (between a classification system and a thesaurus); 2) equivalence and, hence, translatability problems in terms of the natural languages involved. Additionally, the question of ambiguity given the co-occurrence of terms in more than one class, will be discussed with reference to homographs and polysemantic words. In a thesaurus with such a wide coverage yet with a low specificity level, the method adopted in the thesaurus construction was to provide as many lead-in terms as possible and post them up to the closest in meaning broader term in order to improve the recall ratio

    Abstract
    The second edition of the Bibliographic Classidication of H.E. Bliss (BC2), being prepared under the editorship of Jack Mills, Vanda Broughton and others, is a rich source of structure and terminology for thesauri covering different subject fields. The new edition employs facet analysis and is thesaurus-compatible. A number of facet-based thesauri have drawn upon Bliss for terms and relationships. In two of these thesauri the Bliss Classification was the source of both systematic and alphabetical displays. The DHSS-DATA thesaurus, published by the United Kingdom Department of Health and Social Security, provides controlled terms and Bliss class numbers for indexing and searching the DHSS-DATA database. The ECOT thesaurus (Educational courses and occupations thesaurus) prepared for the Department of Education and Science, uses the software sedigned for the British Standards Institution ROOT thesaurus to genearte an alphabetical display from the systematic display derived from the Bliss schedules. Problems, benefits, and future prospects of Bliss-based thesaurus construction are discussed

    Abstract
    The article describes the research done over a bibliographic database in order to show the impact the specificity of the knowledge organising tools may have on information retrieval (IR). For this purpose two multilingual Universal Decimal Classification (UDC) based thesauri having different degrees of specificity are considered. Issues of harmonising a classificatory structure with a thesaurus structure are introduced, and significant aspects of information retrieval in a multilingual environment are examined in an extensive manner. Aspects of complementarity are discussed with particular emphasis on the real impact produced on IR by alternative search facilities. Finally, a number of conclusions are formulated as they arise from the study.

    Abstract
    There are many advantages for Digital Libraries in indexing with classifications or thesauri, but some current disincentive in the lack of flexible retrieval tools that deal with compound descriptors. This demonstration of a research prototype illustrates a matching function for compound descriptors, or multi-concept subject headings, that does not rely on exact matching but incorporates term expansion via thesaurus semantic relationships to produce ranked results that take account of missing and partially matching terms. The matching function is based on a measure of semantic closeness between terms.The work is part of the EPSRC funded FACET project in collaboration with the UK National Museum of Science and Industry (NMSI) which includes the National Railway Museum. An export of NMSI's Collections Database is used as the dataset for the research. The J. Paul Getty Trust's Art and Architecture Thesaurus (AAT) is the main thesaurus in the project. The AAT is a widely used thesaurus (over 120,000 terms). Descriptors are organised in 7 facets representing separate conceptual classes of terms.The FACET application is a multi tiered architecture accessing a SQL Server database, with an OLE DB connection. The thesauri are stored as relational tables in the Server's database. However, a key component of the system is a parallel representation of the underlying semantic network as an in-memory structure of thesaurus concepts (corresponding to preferred terms). The structure models the hierarchical and associative interrelationships of thesaurus concepts via weighted poly-hierarchical links. Its primary purpose is real-time semantic expansion of query terms, achieved by a spreading activation semantic closeness algorithm. Queries with associated results are stored persistently using XML format data. A Visual Basic interface combines a thesaurus browser and an initial term search facility that takes into account equivalence relationships. Terms are dragged to a direct manipulation Query Builder which maintains the facet structure.
