    Abstract
    Im Zuge zunehmender Globalisierung werden Wissensorganisationssysteme erforderlich, die ein sprachunabhängiges Retrieval ermöglichen, ohne dass dadurch bereits existierende und national bewährte Wissenssysteme obsolet werden. Das durch die Deutsche Forschungsgemeinschaft (DFG) geförderte und von der Deutschen Nationalbibliothek in Kooperation mit der Fachhochschule Köln durchgeführte Projekt CrissCross leistet einen wesentlichen Beitrag zur Schaffung eines solchen Wissensspeichers, indem es die Sachschlagwörter der deutschen Schlagwortnormdatei (SWD) mit Notationen der Dewey-Dezimalklassifikation sowie mit ihren Äquivalenten der Library of Congress Subject Headings (LCSH) und der französischen Schlagwortsprache RAMEAU (Repertoire d'autorité-matière encyclopédique et alphabétique unifié) verknüpft. Ein erweitertes multilinguales und thesaurusbasiertes Recherchevokabular wird erstellt, das für die inhaltliche Suche nach Dokumenten in heterogen erschlossenen Beständen verwendet werden kann. In diesem Artikel wird die Problematik bei der Verknüpfung semantisch heterogener Systeme unter besonderer Berücksichtigung der Unterschiede zwischen der DDC und der SWD skizziert. Die in CrissCross gewählte Methodik bei der Verknüpfung von SWD und DDC wird vorgestellt. Abschließend wird der Nutzen der erstellten Daten für das Retrieval aufgezeigt.

    Abstract
    Within the multilingual framework of the CrissCross project, MACS (Multilingual Access to Subjects) has continued its work. MACS has developed a prototype of mappings between three vocabularies: the LCSH (Library of Congress Subject Headings), RAMEAU (Répertoire d'autorité-matière encyclopédique et alphabétique unifié) and the SWD (Schlagwortnormdatei). A database with a Link Management System (LMI), which allows for an easy linking between English, French and German subject headings, was created. The database started working with headings from the disciplines sports and theatre, but by now headings from all other fields of knowledge have been included as well. In 2008-2010, equivalencies between English and French headings which had been produced by the Bibliothèque nationale de France have been completed with the most important German SWD topical terms. Thus, more than 50.000 trilingual links are now available and can be used in different retrieval scenarios. It is planned to use them in The European Library (TEL) in order to support multilingual searches over all European National Library collections. The article informs about the project workflow, methodology of mapping and future applications of MACS links.

    Abstract
    The German subject headings authority file - SWD - provides a terminologically controlled vocabulary, covering all fields of knowledge. The subject headings are determined by the German Rules for the Subject Catalogue. The authority file is produced and updated daily by participating libraries from around Germany, Austria and Switzerland. Over the last twenty years, it grew to an online-accessible database with about 550.000 headings. They are linked to other thesauri, also to French and English equivalents and with notations of the Dewey Decimal Classification. Thus, it allows multilingual access and searching in dispersed, heterogeneously indexed catalogues. The vocabulary is not only used for cataloguing library materials, but also web-resources and objects in archives and museums.

    Abstract
    Data from multiple knowledge organization systems are combined to provide a global overview of the content holdings of a small personal library. Subject headings and classification data are used to effectively map the combined book and topic space of the library. While harvested and manipulated by hand, the work reveals issues and potential solutions when using automated techniques to produce topic maps of much larger libraries. The small library visualized consists of the thirty-nine, digital, English language books found in the Osama Bin Laden (OBL) compound in Abbottabad, Pakistan upon his death. As this list of books has garnered considerable media attention, it is worth providing a visual overview of the subject content of these books - some of which is not readily apparent from the titles. Metadata from subject headings and classification numbers was combined to create book-subject maps. Tree maps of the classification data were also produced. The books contain 328 subject headings. In order to enhance the base map with meaningful thematic overlay, library holding count data was also harvested (and aggregated from duplicates). This additional data revealed the relative scarcity or popularity of individual books.

    Abstract
    This article presents an Italian experience of developing streamlined semantic interoperability between the Italian Thesaurus of Nuovo soggettario and the Library of Congress Subject Headings (LCSH). This ongoing project must take into consideration the differences between the two indexing tools, while the criteria on which the resulting actions are based are being clarified continually. Reciprocal interoperability, thanks to the Simple Knowledge Organization System format, enables us to create links with English language subject headings. The National Central Library of Florence is studying methods of automatically catching LCSH equivalents and the question of how to take advantage of both Semantic Web outputs and the multilingual dataset of Wikidata.

    Abstract
    The treatment of subjects by Functional Requirements for Bibliographic Records (FRBR) has attracted less attention than some of its other aspects, but there seems to be a general consensus that it needs work. While some have proposed elaborating its subject categories-concepts, objects, events, and places-to increase their semantic complexity, a working group of the International Federation of Library Associations and Institutions (IFLA) has recently made a promising proposal that essentially bypasses those categories in favor of one entity, thema. This article gives an overview of the proposal and discusses its relevance to another difficult problem, ambiguities in the establishment of headings for buildings.Use of dynamic links from subject-based finding aids to records for electronic resources in the OPAC is suggested as one method for by-passing the OPAC search interface, thus making the library's electronic resources more accessible. This method simplifies maintenance of links to electronic resources and aids instruction by providing a single, consistent access point to them. Results of a usage study from before and after this project was completed show a consistent, often dramatic increase in use of the library's electronic resources.

    Abstract
    The paper discusses the importance of these initiatives in releasing as linked data the very large quantities of rich, professionally-generated metadata stored in formats based on these standards, such as UNIMARC and MARC21, addressing such issues as critical mass for semantic and statistical inferencing, integration with user- and machine-generated metadata, and authenticity, veracity and trust. The paper also discusses related initiatives to release controlled vocabularies, including the Dewey Decimal Classification (DDC), ISBD, Library of Congress Name Authority File (LCNAF), Library of Congress Subject Headings (LCSH), Rameau (French subject headings), Universal Decimal Classification (UDC), and the Virtual International Authority File (VIAF) as linked data. Finally, the paper discusses the potential collective impact of these initiatives on metadata workflows and management systems.

    Abstract
    In economics there exists an internationally established classification system. Research literature is usually classified according to the JEL classification codes, a classification system originated by the Journal of Economic Literature and published by the American Economic Association (AEA). Complementarily to keywords which are usually assigned freely, economists widely use the JEL codes when classifying their publications. In cooperation with KU Leuven, ZBW - Leibniz Information Centre for Economics has published an unofficial multilingual version of JEL in SKOS format. In addition to this, exists the STW Thesaurus for Economics a bilingual domain-specific controlled vocabulary maintained by the German National Library of Economics (ZBW). Developed in the mid-1990s and since then constantly updated according to the current terminology usage in the latest international research literature in economics it covers all sub-fields both in the economics as well as in business economics and business practice containing subject headings which are clearly delimited from each other. It has been published on the web as Linked Open Data in the year 2009.

    Abstract
    Am 29. und 30. Oktober 2009 fand in der Königlichen Bibliothek in Den Haag das zweite internationale UDC-Seminar zum Thema "Classification at a Crossroad" statt. Organisiert wurde diese Konferenz - wie auch die erste Konferenz dieser Art im Jahr 2007 - vom UDC-Konsortium (UDCC). Im Mittelpunkt der diesjährigen Veranstaltung stand die Erschließung des World Wide Web unter besserer Nutzung von Klassifikationen (im Besonderen natürlich der UDC), einschließlich benutzerfreundlicher Repräsentationen von Informationen und Wissen. Standards, neue Technologien und Dienste, semantische Suche und der multilinguale Zugriff spielten ebenfalls eine Rolle. 135 Teilnehmer aus 35 Ländern waren dazu nach Den Haag gekommen. Das Programm umfasste mit 22 Vorträgen aus 14 verschiedenen Ländern eine breite Palette, wobei Großbritannien mit fünf Beiträgen am stärksten vertreten war. Die Tagesschwerpunkte wurden an beiden Konferenztagen durch die Eröffnungsvorträge gesetzt, die dann in insgesamt sechs thematischen Sitzungen weiter vertieft wurden.

    Abstract
    This paper reports on the second part of an initiative of the authors on researching classification systems with the conceptual model defined by the Functional Requirements for Subject Authority Data (FRSAD) final report. In an earlier study, the authors explored whether the FRSAD conceptual model could be extended beyond subject authority data to model classification data. The focus of the current study is to determine if classification data modeled using FRSAD can be used to solve real-world discovery problems in multicultural and multilingual contexts. The paper discusses the relationships between entities (same type or different types) in the context of classification systems that involve multiple translations and /or multicultural implementations. Results of two case studies are presented in detail: (a) two instances of the DDC (DDC 22 in English, and the Swedish-English mixed translation of DDC 22), and (b) Chinese Library Classification. The use cases of conceptual models in practice are also discussed.

    Abstract
    The publication of library legacy includes publication of structuring vocabularies such as thesauri, classifications, subject headings. Different sources use different vocabularies, different in structure, width, depth and scope, and languages. Federated access to distributed data collections is currently possible if they rely on the same vocabularies. Mapping techniques and standards supporting them (such as SKOS mapping properties, OWL sameAs and equivalentClass) are still largely experimental, even in the linked data land. Libraries use a variety of controlled subject vocabulary and classification schemes to index items in their collections. Although most collections will employ only a single scheme, different schemes may be chosen to index different collections within a library or in separate libraries; schemes are chosen on the basis of language, subject focus (general or specific), granularity (specificity), user expectation, and availability and support (cost, currency, completeness, tools). For example, a typical academic library will operate separate metadata systems for the library's main collections, special collections (e.g. manuscripts, archives, audiovisual), digital collections, and one or more institutional repositories for teaching and research output; each of these systems may employ a different subject vocabulary, with little or no interoperability between terms and concepts. Users expect to have a single point-of-search in resource discovery services focussed on their local institutional collections. Librarians have to use complex and expensive resource discovery platforms to meet user expectations. Library communities continue to develop resource discovery services for consortia with a geographical, subject, sector (public, academic, school, special libraries), and/or domain (libraries, archives, museums) focus. Services are based on distributed searching (e.g. via Z39.50) or metadata aggregations (e.g. OCLC's WorldCat and OAISter). As a result, the number of different subject schemes encountered in such services is increasing. Trans-national consortia (e.g. Europeana) add to the complexity of the environment by including subject vocabularies in multiple languages. Users expect single point-of-search in consortial resource discovery service involving multiple organisations and large-scale metadata aggregations. Users also expect to be able to search for subjects using their own language and terms in an unambiguous, contextualised manner.

    Die erste Session der Veranstaltung war dem von der DFG geförderten Projekt CrissCross gewidmet, das von der Fachhochschule Köln in Kooperation mit der Deutschen Nationalbibliothek durchgeführt wird. Das Projekt, das 2006 begann und im Herbst diesen Jahres endet, verfolgt das Ziel, ein multilinguales, thesaurusbasiertes und nutzerfreundliches Recherchevokabular zu heterogen erschlossenen Informationsressourcen zu schaffen. Hierzu wird einerseits eine unidirektionale Verbindung zwischen Sachschlagwörtern der Schlagwortnormdatei (SWD) und Notationen der Dewey-Dezimalklassifikation hergestellt, andererseits werden - in Fortführung der in dem Projekt Multilingual Access to Subject Headings (MACS) entwickelten Methodik - häufig verwendete SWD-Schlagwörter mit ihren Äquivalenten in der englischen Schlagwortsprache Library of Congress Subject Headings (LCSH) und der französischen Schlagwortsprache Répertoire d'autorité-matière encyclopédique et alphabétique unifié (RAMEAU) verknüpft. Jan-Helge Jacobs, Katrin Müller und Tina Mengel von der Fachhochschule Köln gaben einen Überblick über das für das Projekt spezifische SWD-DDC-Mapping. Sie erläuterten die zugrunde liegende Methodik und stellten den mit den Daten gegebenen möglichen Mehrwert sowohl zur Verbesserung des Zugangs zur DDC und zu DDC-erschlossenen Informationsressourcen im Allgemeinen als auch zur Unterstützung von explorativen Suchprozessen im Speziellen dar. Ergänzend präsentierten Yvonne Jahns und Helga Karg von der Deutschen Nationalbibliothek den im MACSProjekt praktizierten Ansatz zur Verbindung von Indexierungsinstrumenten verschiedener Sprachen und das damit gegebene Potential zur Unterstützung eines multilingualen Retrievals. Die adäquate Modellierung von Dokumentationssprachen und Relationen zur Gewährleistung von Interoperabilität und Verbesserung von Suchfunktionalitäten bei heterogen erschlossenen Dokumentbeständen besonders in Hinblick auf Semantic-Web-Applikationen war Thema der zweiten Session. Jessica Hubrich von der Fachhochschule Köln nahm theoretische Ergebnisse des CrissCross-Projektes auf und stellte ein gestuftes Interoperabilitätsmodell vor, in dem Methoden zur Erstellung von Links zwischen Begriffen verschiedener Wissenssysteme in Bezug gesetzt wurden zu spezifischen Suchfunktionalitäten in Retrievalszenarien. Im anschließenden Vortrag von Claudia Effenberger und Julia Hauser von der Deutschen Nationalbibliothek wurde von den bisherigen Ergebnissen eines an der Deutschen Nationalbibliothek angesiedelten Forschungsprojekts berichtet, in dem jeder Klasse der Dewey-Dezimalklassifikation ein eindeutiger Identifier zugeordnet wird, durch den verschiedene Versionen einer Klasse unterschieden werden können. Dies dient der Verbesserung des Zugriffs auf bibliografische Titeldaten, die auf der Basis unterschiedlicher DDC-Versionen erschlossen wurden. Der erste Tag schloss mit einer Präsentation von Antoine Isaac von der Vrije Universiteit in Amsterdam ab. In dieser wurde Interoperabilität als Teil eines semantischen Netzes von Linked Data diskutiert und ein Überblick über zentrale Linked-Data-Projekte gegeben.
