- Abstract
- Das Problem der Wahrnehmung und Darstellung von Wahrheit durch die Medien führt zu vier zentralen Fragen: Wie viel Wahrheit gibt es in der Welt, über die Journalisten berichten müssen? Wie ermittelt oder recherchiert man diese Wahrheit? Wie trennt man die Spreu vom Weizen? Und wie geht man als Journalist mit dem um, was man als Wahrheit erkannt hat oder erkannt zu haben glaubt? Hier gibt es ganz offensichtlich eine Parallele zwischen Journalisten und Wissenschaftlern. Journalisten und Wissenschaftler brauchen erstens Hypothesen, zweitens geeignete Hypothesentests, drittens ein gutes Abgrenzungs-Kriterium und viertens Verfahren, um die erkannten Sachverhalte auf angemessene Weise für eine Kommunikation mit anderen zu repräsentieren, das heißt sie darzustellen. Es gibt zwei große Unterschiede zwischen Journalisten und Wissenschaftlern: Journalisten sind in der Regel auf raum-zeitlich begrenzte Aussagen aus, Wissenschaftler in der Regel auf raumzeitlich unbegrenzte Gesetze. Aber diese Unterschiede sind fließend, weil Wissenschaftler raum-zeitlich begrenzte Aussagen brauchen, um ihre All-Aussagen zu überprüfen, und Journalisten sich immer häufiger auf das Feld der allgemeinen Gesetzes-Aussagen wagen oder doch zumindest Kausalinterpretationen für soziale Phänomene anbieten. Der zweite Unterschied besteht darin, dass die Wissenschaft weitgehend professionalisiert ist (zumindest gilt dies uneingeschränkt für die Naturwissenschaften und die Medizin), was ihr relativ klare Abgrenzungs- und Güte-Kriterien beschert hat. Diese fehlen weitgehend im Journalismus.

- Abstract
- Vorgestellt wird die Konstruktion eines thematisch geordneten Thesaurus auf Basis der Sachschlagwörter der Gemeinsamen Normdatei (GND) unter Nutzung der darin enthaltenen DDC-Notationen. Oberste Ordnungsebene dieses Thesaurus werden die DDC-Sachgruppen der Deutschen Nationalbibliothek. Die Konstruktion des Thesaurus erfolgt regelbasiert unter der Nutzung von Linked Data Prinzipien in einem SPARQL Prozessor. Der Thesaurus dient der automatisierten Gewinnung von Metadaten aus wissenschaftlichen Publikationen mittels eines computerlinguistischen Extraktors. Hierzu werden digitale Volltexte verarbeitet. Dieser ermittelt die gefundenen Schlagwörter über Vergleich der Zeichenfolgen Benennungen im Thesaurus, ordnet die Treffer nach Relevanz im Text und gibt die zugeordne-ten Sachgruppen rangordnend zurück. Die grundlegende Annahme dabei ist, dass die gesuchte Sachgruppe unter den oberen Rängen zurückgegeben wird. In einem dreistufigen Verfahren wird die Leistungsfähigkeit des Verfahrens validiert. Hierzu wird zunächst anhand von Metadaten und Erkenntnissen einer Kurzautopsie ein Goldstandard aus Dokumenten erstellt, die im Online-Katalog der DNB abrufbar sind. Die Dokumente vertei-len sich über 14 der Sachgruppen mit einer Losgröße von jeweils 50 Dokumenten. Sämtliche Dokumente werden mit dem Extraktor erschlossen und die Ergebnisse der Kategorisierung do-kumentiert. Schließlich wird die sich daraus ergebende Retrievalleistung sowohl für eine harte (binäre) Kategorisierung als auch eine rangordnende Rückgabe der Sachgruppen beurteilt.

- Abstract
- Für eine fiktive Dokumentmenge wird eine Dokument-Wort-Matrix erstellt und mittels zweier Suchanfragen, ebenfalls als Matrix dargestellt, die Retrievalergebnisse ermittelt. Den Wörtern der Dokumentmenge werden in einem zweiten Schritt Aspekte zugeordnet und die Untersuchung erneut durchgeführt. Ein Vergleich bestätigt die schon früher gefundenen Vorteile des aspektischen Indexierung gegenüber anderen Methoden der Retrievalverbesserung, wie Trunkierung und Controlled Terms

- Abstract
- Webangebote wissenschaftlicher Bibliotheken werden häufig nur eingeschränkt, erfolglos oder mit großen Schwierigkeiten genutzt. Im Verlauf eines zweijährigen, von der Deutschen Forschungsgemeinschaft finanzierten Projektes an der Universität Gießen konnten detaillierte empirische Erkenntnisse über Nutzeraktivitäten, Nutzerstrategien und -probleme ermittelt werden, die sich in eine Typologie von Problemen und Problemursachen sowie einen Empfehlungskatalog für nutzerfreundliche Webangebote umsetzen ließen. In Teilbereichen haben diese Ergebnisse bereits Eingang in die Neugestaltung der Webseiten des Bibliothekssystems der Universität Gießen gefunden.

- Abstract
- Ein Bericht über die Ergebnisse und die Prozessanalyse einer automatischen Indexierung mit Mehrwortgruppen. Diese Bachelorarbeit beschreibt, inwieweit der Inhalt informationswissenschaftlicher Fachtexte durch informationswissenschaftliches Fachvokabular erschlossen werden kann und sollte und dass in diesen wissenschaftlichen Texten ein Großteil der fachlichen Inhalte in Mehrwortgruppen vorkommt. Die Ergebnisse wurden durch eine automatische Indexierung mit Mehrwortgruppen mithilfe des Programme Lingo an einer informationswissenschaftlichen Datenbank ermittelt.
