    Abstract
    After a period of experiment and evolution in the 1950s and 1960s, a fairly standard format for thesauri was established with the publication of the influential Thesaurus of Engineering and Scientific Terms (TEST) in 1967. This and other early thesauri relied primarily an the presentation of terms in alphabetical order. The value of a classified presentation was subsequently realised, and in particular the technique of facet analysis has profoundly influenced thesaurus evolution. Thesaurofacet and the Art & Architecture Thesaurus have acted as models for two distinct breeds of thesaurus using faceted displays of terms. As of the 1990s, the expansion of end-user access to vast networked resources is imposing further requirements an the style and structure of controlled vocabularies. The international standards for thesauri, first conceived in a print-based era, are badly in need of updating. Work is in hand in the UK and the USA to revise and develop standards in support of electronic thesauri.

    Abstract
    An African Studies Thesaurus was constructed for the purpose of subject indexing and retrieval in the Library of the African Studies Centre (ASC) in Leiden in 2001-2006. A word-based system was considered a more user-friendly alternative to the Universal Decimal Classification (UDC) codes which were used for subject access in the ASC catalogue at the time. In the process of thesaurus construction UDC codes were used as a starting point. In addition, when constructing the thesaurus, each descriptor was also assigned a UDC code from the recent edition of the UDC Master Reference File (MRF), thus replacing many of the old UDC codes used by then, some of which dated from the 1952 French edition. The presence of the UDC codes in the thesaurus leaves open the possibility of linking the thesaurus to different language versions of the UDC MRF in the future. In a parallel but separate operation each UDC code which had been assigned to an item in the library's catalogue was subsequently converted into one or more thesaurus descriptors.

    Abstract
    Thesaurus-Crosskonkordanzen bilden eine wichtige Voraussetzung für die integrierte Suche in einer verteilten Datenstruktur. Ihr Aufbau erfordert allerdings erhebliche personelle Ressourcen. Der vorliegende Beitrag liefert Evaluationsergebnisse des Library Track 2012 der Ontology Alignment Evaluation Initiative (OAEI), in dem Crosskonkordanzen zwischen dem Thesaurus Sozialwissenschaften (TheSoz) und dem Standard Thesaurus Wirtschaft (STW) erstmals automatisch erstellt wurden. Die Evaluation weist auf deutliche Unterschiede in den getesteten Matching- Tools hin und stellt die qualitativen Unterschiede einer automatisch im Vergleich zu einer intellektuell erstellten Crosskonkordanz heraus. Die Ergebnisse sprechen für einen Einsatz automatisch generierter Thesaurus-Crosskonkordanzen, um Domänenexperten eine maschinell erzeugte Vorselektion von möglichen Äquivalenzrelationen anzubieten.

    Abstract
    THESYS is based on the natural language processing of free-text databases. It yields statistically evaluated correlations between words of the database. These correlations correspond to traditional thesaurus relations. The person who has to build a thesaurus is thus assisted by the proposals made by THESYS. THESYS is being tested on commercial databases under real world conditions. It is part of a text processing project at Siemens, called TINA (Text-Inhalts-Analyse). Software from TINA is actually being applied and evaluated by the US Department of Commerce for patent search and indexing (REALIST: REtrieval Aids by Linguistics and STatistics)

    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
    The present study investigates the ability of a bibliometric based semi-automatic method to select candidate thesaurus terms from citation contexts. The method consists of document co-citation analysis, citation context analysis, and noun phrase parsing. The investigation is carried out within the specialty area of periodontology. The results clearly demonstrate that the method is able to select important candidate thesaurus terms within the chosen specialty area.

    Abstract
    The development of the general theory of subject indexing language and of POPSI for organisation, storage and retrieval of subjects embodies in documents has a striking parallel in the search for and development of 'universal forms' and 'deep structure' in language and linguistic studies. This paper briefly traces the development of POPSI language as a metalanguage for information organisation and for generating information retrieval thesaurus. Also a computer-based system for generating an information retrieval thesaurus from modulated subject headings formulated according to POPSI which are enriched with certain codes for relating the terms in the subject headings is described. It is also mentioned that, if it is possible to form a table of equivalent terms in another language for the terms already used to generate the thesaurus, then it is possible to translate the thesaurus automatically into the other language

    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
    In order to enhance the use of Universal Decimal Classification (UDC) numbers in information retrieval, the authors have represented classification with multilingual thesaurus descriptors and implemented this solution in an automated way. The authors illustrate a solution implemented in a BiblioPhil library system. The standard formats used are UNIMARC for subject authority records (i.e. the UDC-based multilingual thesaurus) and MARC XML support for data transfer. The multilingual thesaurus was built according to existing standards, the constituent parts of the classification notations being used as the basis for search terms in the multilingual information retrieval. The verbal equivalents, descriptors and non-descriptors, are used to expand the number of concepts and are given in Romanian, English and French. This approach saves the time of the indexer and provides more user-friendly and easier access to the bibliographic information. The multilingual aspect of the thesaurus enhances information access for a greater number of online users

    Abstract
    Reports on a research project aimed at constructing a thesaurus to be used for indexing materials in the area of law. it was observed that despite the importance of specialized controlled vocabularies, none has been made for law. In the project, terms used by practitioners and those in literature were compared to produce a balanced thesaurus. 1000 terms were selected from the literature of law and sent to 60 law experts for their comments and suggestions. Analysis was then carried out using the student t-test statistic. It was observed that there was no significant difference between the terms used by the lawyers and those in law literature
