    Abstract
    New forms of man-machine interaction are becoming available that have great power for the delivery of information. But the scales of speed and capacity on which the computing machines operate demand new thoughts as to how information can be stored and retrieved. The objective of the discussion in this paper is to argue for a combination of natural-language processing and subject classification to be able to meet the demands

    Abstract
    In the early 1990s, indexing with classification codes from the Universal Decimal Classification (UDC) in an academic library, going from traditional to automated routines in any and all its activities, suddenly proved insufficient. Under the circumstances of online searching, the possibilities offered by the new OPAC looked much more attractive to indexers and searchers alike. Therefore, a quick shift to indexing with UDC and keywords instead of UDC numbers alone was made. Currency, precision and, more importantly, user-friendliness were strong advantages offered by keyword indexing and searching. But the larger the dictionary of keywords, the more problematic the consequences an information scattering, given the lack of control an terms. The present paper describes the advantages of the UDC in indexing by presenting some of the devices it is provided with: subdivision by analogy, common and special auxiliaries, use of synthesis, and use of connecting symbols. The solution of indexing with both UDC notation and words from a thesaurus based an UDC was prompted by some other characteristics of the schedules: a semi-faceted classification system, hierarchical organisation, richness in terminology and consistency and control of notation. The methodology used in building the thesaurus is conceived according to the international standards (ISO 2788 and 5964) to which some principles have been added, giving the specific approach of harmonising a classification structure with that of a thesaurus. Compatibility and translatability issues are also considered and some problems arising from them are treated in detail. Most of the problems discussed are illustrated with examples.

    Abstract
    Both classification systems and thesauri have their specific strengths and weaknesses. Through properly combining both approaches one can eliminate the latter and largely preserve the strenghts. 'Classauri' which originate in this well-known way are most effective if they are constructed and applied during computer-aided indexing. A special variety of classaurus is described which is characterized by the employment of simple bur highly effective conceptual and technical devices and by the renunciation of attempts to generate the wording of index entries algorithmically

    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.

    Relative Index (RI) terms in the Dewey Decimal Classification (DDC) system correspond to concepts that either approximate the whole of the class they index or that are in standing room there. DDC conventions and shallow natural language processing are used to determine automatically whether specific RI terms approximate the whole of or are in standing room in the classes they index. Approximately three-quarters of all RI terms are processed by the techniques described.

    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
    Czech authority file of topical terms is intended to form a base for multilingual controlled vocabulary. The aim of the proposal is to provide users of online library catalogues and internet services of cooperating institutions with an indexing and retrieval tool which enables multilingual and cross-domain searching ("one-stop" seamless searching). The goal of the project is to establish a multilingual subject approach to catalogues of participating libraries (Czechia, Croatia, Latvia, Lithuania, Macedonia, Slovakia, and Slovenia). In practice this means that a user in any of these countries would enter a query in his local language and receive hits from all the catalogues. The initiative is complying with the main goals currently defined by IFLA for the activity of Indexing and Classification Section, it means: Changing Roles of Subject Access Tools (Berlin), Implementation and Adaptation of Global Tools for Subject Access to Local Needs (Buenos Aires), and Cataloguing and Subject Tools for Global Access: International Partnerships (Oslo).

    The aim of this initiative is to provide the users of online library catalogues and information gateways of cooperating libraries with a prototype for multilingual subject searching in online environment. Library collections of these libraries are large and without any doubt very valuable for researchers throughout Europe. What is needed is a standardized, authorized indexing and retrieval tool which would bring together all their catalogues and databases and enable multilingual subject searching. At the beginning of the project, a number of factors affecting subject indexing in current environment and cross-searching for subjects have been identified. These factors include - standardization of subject retrieval process and indexing and classification tools - subject retrieval methods - possibility of interoperability among different indexing and classification schemes - multilingualism issue - possibility to increase precision and recall trough Z39.50 protocol and its profiles and to apply authority control in subject retrieval process - need for cooperation

    Abstract
    This paper discusses two inter-related themes: the retrieval potential of faceted thesauri and XML representations of fundamental facets. Initial findings are discussed from the ongoing 'FACET' project, in collaboration with the National Museum of Science and Industry. The work discussed seeks to take advantage of the structure afforded by faceted systems for multi-term queries and flexible matching, focusing in this paper an the Art and Architecture Thesaurus. A multi-term matching function yields ranked results with partial matches via semantic term expansion, based an a measure of distance over the semantic index space formed by thesaurus relationships. Our intention is to drive the system from general representations and a common query structure and interface. To this end, we are developing an XML representation based an work by the Classification Research Group an fundamental facets or categories. The XML representation maps categories to particular thesauri and hierarchies. The system interface, which is configured by the mapping, incorporates a thesaurus browser with navigation history together with a term search facility and drag and drop query builder.

    An diesem Punkt setzt das neue Projekt CrissCross an, das gemeinsam von der Deutschen Nationalbibliothek (DNB) und der Fachhochschule Köln betrieben und von der Deutschen Forschungsgemeinschaft (DFG) gefördert wird. CrissCross schafft Verbindungslinien zwischen einigen besonders verbreiteten und bewährten Erschließungsinstrumenten: Der deutschsprachigen Schlagwortnormdatei (SWD), den besonders im angloamerikanischen Raum verbreiteten Library of Congress Subject Headings (LCSH), der französischen Dokumentationssprache Répertoire d'autorité-matière encyclopédique et alphabétique unifié (Rameau) und der Dewey Decimal Classification (DDC) als dem international am meisten verbreiteten Klassifikationssystem. CrissCross kann dabei auf zwei wichtigen Vorgängerprojekten aufbauen. Hier ist zum einen das ebenfalls von DNB und der Fachhochschule Köln gemeinsam betriebene Vorgängerprojekt »DDC Deutsch« zu nennen. Bereits während dessen Laufzeit war deutlich geworden, wie vorteilhaft sich eine Anreicherung des DDC-Registers mit dem Schlagwortbestand der SWD auf die Klassifikationspraxis auswirken könnte. Genau dieser Schritt wird nun vollzogen, wobei sich die Projektarbeit auf die Sachschlagwörter konzentriert - kein kleines Unterfangen, beläuft sich doch die Zahl der zurzeit in der SWD befindlichen Datensätze mit dem Indikator s auf über 154.000.

    "Unsere Sitzung fand diesmal am 13. 9. 2005 in Bozen im Rahmen der ODOK statt. Es waren daher auch viele interessierte Südtiroler und italienische Sacherschließungskollegen/-innen zu Gast. Eine der beiden Konferenzsprachen war Englisch, und so konnten wir Mehrsprachigkeit, das Thema unserer Sitzung und der beiden Gastvorträge, gleich selbst praktizieren. Patrice LANDRY, der Leiter der Sacherschließung an derSLB in Bern, der seit kurzem den Vorsitz der IFLA-Sektion "Classification and Indexing" und der Arbeitsgruppe "Guidelines for subject access for national bibliographic agencies" übernommen hatte, referierte über den jüngsten Stand des Projekts MACS (Multilingual Access to Subjects) und ließ uns am Nachmittag in seinem Workshop hinter die Kulissen der bereits mit echten Titeldaten operierenden Suchoberfläche blicken. Er zeigte die verschiedenen Recherche- und Editier-Funktionen im Management Linking System und brachte Beispiele für die kooperative Bearbeitung an einigen Datensätzen der bisher bereits miteinander verzahnten Normdateien SWD, LCSH und RAMEAU. Schließlich eröffnete er Ausblicke auf die künftige Einbindung weiterer Sprachen, etwa des Italienischen durch den Soggetario und auf die Anreicherung der Daten, etwa mit DDC-Notationen durch die Nähe zum DDB-Projekt "CrissCross". Federica PARADISI, die in der Sacherschließungsabteilung der BNC in Florenz sowohl für die italienische Übersetzung der DDC und deren Anwendung in ganz Italien als auch für die Überarbeitung des seit 1956 existierenden italienischen Wortschatzes für die verbale Erschließung und für dessen Aufbereitung zu einer modernen, bald auch elektronischen Normdatei zuständig ist und an der Erstellung der italienischen Nationalbibliografie mitwirkt, hat zuletzt gemeinsam mit Anna Lucarelli den Prototyp des "Nuovo Soggetario" erarbeitet und stellte dieses umfangreiche Projekt vor. Der von ihr skizzierte Zeitplan gibt Anlass zur Hoffnung, dass MACS für die Auffindung beschlagworteter Literatur in Bibliothekskatalogen schon in einem Jahr um einen sprachlichen Zugang reicher sein könnte. Beide Gastreferenten/-innen standen dem Auditorium im Anschluss an die Präsentationen für Fragen zur Verfügung, und die neuen fachlichen Kontakte vertieften sich in den Pausengesprächen noch mehr. Vor der Führung durch die Dewey-Ausstellung im Lichthof der UB Bozen demonstrierte Margit SANDNER zum Abschluss dieses multilingualen Sacherschließungsnachmittags mit einigen Beispielen in deutscherSprache die Suchfunktionen in den beiden Webversionen von DDC Deutsch MelvilSearch (für OPACs) und MelvilClass (für das Klassifizieren) und kündigte an, dass ab Oktober bis Jahresende kostenlose Testaccounts vergeben werden. Wer daran interessiert ist, diese deutschsprachigen Webtools bereits auszuprobieren, wendet sich am besten direkt an Herrn Dr. Lars Svensson in Der Deutschen Bibliothek in Frankfurt: svensson@dbf.ddb.de. Die ab Jänner 2006 gültigen Lizenzbedingungen für "Melvil" entnehmen Sie bitte: http//www.ddc-deutsch.de/licence-melvil.html Noch zwei aktuelle Hinweise: - Informationstag der Arbeitsstelle für Standardisierung (DDB) über aktuelle Tendenzen in Sachen Regelwerke f. Formal- und Sacherschließung, Formate, Normdateien und Datentausch am 15. November in Wien. - Aufsatz über die Zukunft der SWD von Esther Scheven (BD 2005, H. 6, S. 748-773), in dem u. a. auch auf unsere seinerzeitige KofSE-Studie: Schlagwort "Benutzerforschung" ... (VÖB-Mitt. 1997, H. 3-4, S. 28-49) rekurriert wird."
