- Abstract
- Nach der Veröffentlichung einer deutschen Übersetzung der Dewey Decimal Classification 22 im Oktober 2005 und ihrer Nutzung zur Inhaltserschließung in der Deutschen Nationalbibliographie seit Januar 2006 stellt sich aus Sicht der deutschen kunsthistorischen Spezialbibliotheken die Frage nach einer möglichen Verwendung der DDC und ihrer generellen Eignung zur Inhalterschließung kunsthistorischer Publikationen. Diese Frage wird vor dem Hintergrund der bestehenden bibliothekarischen Strukturen für die Kunstgeschichte sowie mit Blick auf die inhaltlichen Besonderheiten, die Forschungsmethodik und die publizistischen Traditionen dieses Faches erörtert.

- Abstract
- This work proposes an approach which is intended to meet the particular challenges of Medical Language Processing, in particular medical information retrieval. At its core lies a new type of dictionary, in which the entries are equivalence classes of subwords, i.e., semantically minimal units. These equivalence classes capture intralingual as well as interlingual synonymy. As equivalence classes abstract away from subtle particularities within and between languages and reference to them is realized via a language-independent conceptual system, they form an interlingua. In this work, the theoretical foundations of this approach are elaborated on. Furthermore, design considerations of applications based on the subword methodology are drawn up and showcase implementations are evaluated in detail. Starting with the introduction of Medical Linguistics as a field of active research in Chapter two, its consideration as a domain separated form general linguistics is motivated. In particular, morphological phenomena inherent to medical language are figured in more detail, which leads to an alternative view on medical terms and the introduction of the notion of subwords. Chapter three describes the formal foundation of subwords and the underlying linguistic declarative as well as procedural knowledge. An implementation of the subword model for the medical domain, the MorphoSaurus system, is presented in Chapter four. Emphasis will be given on the multilingual aspect of the proposed approach, including English, German, and Portuguese. The automatic acquisition of (medical) subwords for other languages (Spanish, French, and Swedish), and their integration in already available resources is described in the fifth Chapter.
The proper handling of acronyms plays a crucial role in medical texts, e.g. in patient records, as well as in scientific literature. Chapter six presents an approach, in which acronyms are automatically acquired from (bio-) medical literature. Furthermore, acronyms and their definitions in different languages are linked to each other using the MorphoSaurus text processing system. Automatic word sense disambiguation is still one of the most challenging tasks in Natural Language Processing. In Chapter seven, cross-lingual considerations lead to a new methodology for automatic disambiguation applied to subwords. Beginning with Chapter eight, a series of applications based onMorphoSaurus are introduced. Firstly, the implementation of the subword approach within a crosslanguage information retrieval setting for the medical domain is described and evaluated on standard test document collections. In Chapter nine, this methodology is extended to multilingual information retrieval in the Web, for which user queries are translated into target languages based on the segmentation into subwords and their interlingual mappings. The cross-lingual, automatic assignment of document descriptors to documents is the topic of Chapter ten. A large-scale evaluation of a heuristic, as well as a statistical algorithm is carried out using a prominent medical thesaurus as a controlled vocabulary. In Chapter eleven, it will be shown how MorphoSaurus can be used to map monolingual, lexical resources across different languages. As a result, a large multilingual medical lexicon with high coverage and complete lexical information is built and evaluated against a comparable, already available and commonly used lexical repository for the medical domain. Chapter twelve sketches a few applications based on MorphoSaurus. The generality and applicability of the subword approach to other domains is outlined, and proof-of-concepts in real-world scenarios are presented. Finally, Chapter thirteen recapitulates the most important aspects of MorphoSaurus and the potential benefit of its employment in medical information systems is carefully assessed, both for medical experts in their everyday life, but also with regard to health care consumers and their existential information needs.

- Abstract
- Die ständig steigende Zahl an publizierter Information in immer neuen Formen verlangt besonders von Informations- und Dokumentationseinrichtungen immer präzisere Lösungen zur Erschließung dieser Informationen und ihrer benutzerfreundlichen Aufbereitung. Besonders im derzeitigen Zeitalter der Datenbanken und Online-Kataloge ist die Kombination von verbaler und klassifikatorischer Sacherschließung gefordert, ohne dabei die Verbindung zu den älteren, vielerorts noch (zumindest zusätzlich) in Verwendung befindlichen, Zettelkatalogen zu verlieren. Weltweit ist eine Vielzahl an verschiedenen Klassifikationen im Einsatz. Die Wahl der für eine Einrichtung passenden Klassifikation ist abhängig von ihrer thematischen und informationellen Ausrichtung, der Größe und Art der Bestände und nicht zuletzt von technischen und personellen Voraussetzungen. Auf Seiten der zu wählenden Klassifikation sind die Einfachheit der Handhabung für den Bibliothekar, die Verständlichkeit für den Benutzer, die Erweiterungsfähigkeit der Klassifikation durch das Aufkommen neuer Wissensgebiete und die Einbindung in informationelle Netze mit anderen Einrichtungen von entscheidender Bedeutung. In dieser Arbeit soll die Dewey Dezimalklassifikation (DDC) hinsichtlich dieser Punkte näher beleuchtet werden. Sie ist die weltweit am häufigsten benutzte Klassifikation. Etwa 200.000 Bibliotheken in 135 Ländern erschließen ihre Bestände mit diesem System. Sie liegt derzeit bereits in der 22. ungekürzten Auflage vor und wurde bisher in 30 Sprachen übersetzt. Eine deutsche Komplettübersetzung wird im Jahre 2005 erscheinen. Trotz teils heftig geführter Standardisierungsdebatten und Plänen für die Übernahme von amerikanischen Formalerschließungsregeln herrscht in Bezug auf die Sacherschließung unter deutschen Bibliotheken wenig Einigkeit. Die DDC ist in Deutschland und anderen europäischen Ländern kaum verbreitet, sieht von Großbritannien und von der Verwendung in Bibliografien ab. Diese Arbeit geht demzufolge auf die historischen Gründe dieser Entwicklung ein und wagt einen kurzen Ausblick in die Zukunft der Dezimalklassifikation.

- Abstract
- In the Internet information space, advanced information retrieval (IR) methods and automatic text processing are used in conjunction with traditional knowledge organization systems (KOS). New information technology provides a platform for better KOS publishing, exploitation and sharing both for human and machine use. Networked KOS services are now being planned and developed as powerful tools for resource discovery. They will enable automatic contextualisation, interpretation and query matching to different indexing languages. The Semantic Web promises to be an environment in which the quality of semantic relationships in bibliographic classification systems can be fully exploited. Their use in the networked environment is, however, limited by the fact that they are not prepared or made available for advanced machine processing. The UDC was chosen for this research because of its widespread use and its long-term presence in online information retrieval systems. It was also the first system to be used for the automatic classification of Internet resources, and the first to be made available as a classification tool on the Web. The objective of this research is to establish the advantages of using UDC for information retrieval in a networked environment, to highlight the problems of automation and classification exchange, and to offer possible solutions. The first research question was is there enough evidence of the use of classification on the Internet to justify further development with this particular environment in mind? The second question is what are the automation requirements for the full exploitation of UDC and its exchange? The third question is which areas are in need of improvement and what specific recommendations can be made for implementing the UDC in a networked environment? A summary of changes required in the management and development of the UDC to facilitate its full adaptation for future use is drawn from this analysis.
