Abstract
Die vorliegende Master Thesis setzt sich mit der Frage nach Möglichkeiten der Anreicherung historischer Zeitungen mit semantischen Metadaten auseinander. Sie möchte außerdem analysieren, welcher Nutzen für vor allem geisteswissenschaftlich Forschende, durch die Anreicherung mit zusätzlichen Informationsquellen entsteht. Nach der Darstellung der Entwicklung der interdisziplinären 'Digital Humanities', wurde für die digitale Sammlung historischer Zeitungen (ANNO AustriaN Newspapers Online) der Österreichischen Nationalbibliothek ein Use Case entwickelt, bei dem 'Named Entities' (Personen, Orte, Organisationen und Daten) in ausgewählten Zeitungsausgaben manuell annotiert wurden. Methodisch wurde das Kodieren mit 'TEI', einem Dokumentenformat zur Kodierung und zum Austausch von Texten durchgeführt. Zusätzlich wurden zu allen annotierten 'Named Entities' Einträge in externen Datenbanken wie Wikipedia, Wikipedia Personensuche, der ehemaligen Personennamen- und Schlagwortnormdatei (jetzt Gemeinsame Normdatei GND), VIAF und dem Bildarchiv Austria gesucht und gegebenenfalls verlinkt. Eine Beschreibung der Ergebnisse des manuellen Annotierens der Zeitungsseiten schließt diesen Teil der Arbeit ab. In einem weiteren Abschnitt werden die Ergebnisse des manuellen Annotierens mit jenen Ergebnissen, die automatisch mit dem German NER (Named Entity Recognition) generiert wurden, verglichen und in ihrer Genauigkeit analysiert. Abschließend präsentiert die Arbeit einige Best Practice-Beispiele kodierter und angereicherter Zeitungsseiten, um den zusätzlichen Nutzen durch die Auszeichnung der 'Named Entities' und durch die Verlinkung mit externen Informationsquellen für die BenützerInnen darzustellen.
