    Abstract
    Interdisziplinarität als Kennzeichen des modernen Wissenschaftslebens setzt in Forschung und Lehre eine effiziente Wissenschaftskommunikation voraus, bei der sich die Partner über eine gemeinsame Sprache verständigen können. Klassifikationen und Thesauri übernehmen dabei eine wichtige Rolle. Zu beobachten ist, dass vorhandene Instrumente in ihrem Gefüge zu inflexibel sind, um die komplex ineinander verwobenen Felder der Wissenschaft in ihrer dynamischen Entwicklung adäquat abzubilden, zur (Selbst-)Verständigung über das Wesen und Struktur der Wissenschaftslandschaft sowie zum erfolgreichen Wissensaustausch beizutragen. Ontologien erschließen neue Wege zur Lösung dieser Aufgaben. In einigen Einzelwissenschaften und Teilgebieten ist diesbezüglich eine rege Tätigkeit zu beobachten, es fehlt allerdings noch ein fachübergreifendes Instrumentarium. Im Vortrag wird das von der DFG geförderte Projekt "Entwicklung einer Ontologie der Wissenschaftsdisziplinen" vorgestellt. Es gilt, die oben beschriebene Lücke zu schließen und eine umfassende Ontologie für Erschließung, Recherche und Datenaustausch bei der Wissenschaftskommunikation zu erstellen. Diese Ontologie soll dazu beitragen, eine effiziente Wissenskommunikation, besonders bei interdisziplinären Projekten, zu unterstützen, verfügbare Ressourcen auffindbar zu machen und mögliche Knotenstellen künftiger Kooperationen zu verdeutlichen. Ausgehend von der Kritik an vorhandenen Instrumenten wird derzeit ein Begriffsmodell für die Beschreibung von Wissenschaftsdisziplinen, ihrer zentralen Facetten sowie ihrer interdisziplinären Beziehungen untereinander entwickelt. Das Modell, inspiriert vom Topic Maps Paradigma, basiert auf einer überschaubaren Menge zentraler Konzepte sowie prinzipiell inverser Beziehungen. Eine entsprechende Ontologie wird in unterschiedlichen (technischen) Beschreibungsformaten formuliert werden können. Dies bildet den Grundstein für den Fokus des Projekts, flexible, verteilte, benutzer- wie pflegefreundliche technische Umsetzungen zu entwickeln und mit Kooperationspartnern zu implementieren.

    Abstract
    In order to transfer the Chinese Classified Thesaurus (CCT) into a machine-processable format and provide CCT-based Web services, a pilot study has been conducted in which a variety of selected CCT classes and mapped thesaurus entries are encoded with SKOS. OWL and RDFS are also used to encode the same contents for the purposes of feasibility and cost-benefit comparison. CCT is a collected effort led by the National Library of China. It is an integration of the national standards Chinese Library Classification (CLC) 4th edition and Chinese Thesaurus (CT). As a manually created mapping product, CCT provides for each of the classes the corresponding thesaurus terms, and vice versa. The coverage of CCT includes four major clusters: philosophy, social sciences and humanities, natural sciences and technologies, and general works. There are 22 main-classes, 52,992 sub-classes and divisions, 110,837 preferred thesaurus terms, 35,690 entry terms (non-preferred terms), and 59,738 pre-coordinated headings (Chinese Classified Thesaurus, 2005) Major challenges of encoding this large vocabulary comes from its integrated structure. CCT is a result of the combination of two structures (illustrated in Figure 1): a thesaurus that uses ISO-2788 standardized structure and a classification scheme that is basically enumerative, but provides some flexibility for several kinds of synthetic mechanisms Other challenges include the complex relationships caused by differences of granularities of two original schemes and their presentation with various levels of SKOS elements; as well as the diverse coordination of entries due to the use of auxiliary tables and pre-coordinated headings derived from combining classes, subdivisions, and thesaurus terms, which do not correspond to existing unique identifiers. The poster reports the progress, shares the sample SKOS entries, and summarizes problems identified during the SKOS encoding process. Although OWL Lite and OWL Full provide richer expressiveness, the cost-benefit issues and the final purposes of encoding CCT raise questions of using such approaches.
