English abstract

Web users increasingly have a hard time finding relevant material because traditional full text search engines hit the wall. One solution to overcome these limits is to implement an exploratory search by using semantic web technologies. "Linked Data" describes a "concept" of publishing data through semantic markup of the information and its relations. As a result software can "understand" the meaning of the described information. Due to its structure, bibliographic information lends itself to being semantically rehashed and published as Linked Data. Libraries expect a better visibility in the web and therefore a better use of their services. Currently there are few web applications that use bibliographically linked data. This paper analyses in detail Linked Data web applications and discusses the aspects of data integration, the architecture of Linked Data web applications as well as visualization techniques to implement exploratory searches. For the purpose of this thesis, a prototype of a web application demonstrates which bibliographic information in the Linked Data can be found.

German abstract

Anwenderinnen und Anwender sind im Web zunehmend mit einem Überfluss an Informationen konfrontiert. Die Auswahl relevanter Informationen fällt immer schwerer, da klassische Volltextsuchmaschinen mittlerweile an ihre Grenzen stoßen. Ein Ansatz zur Überwindung dieser Grenzen ist die Implementierung einer explorativen Suche mithilfe semantischer Technologien. "Linked Data" beschreibt ein "Konzept" zum Publizieren von Daten durch semantische Auszeichnung der Informationen und deren Beziehungen. Durch diese semantischen Auszeichnungen wird Computerprogrammen ermöglicht, diese Daten in einem Kontext einzuordnen. Bibliografische Informationen eigenen sich aufgrund ihrer Strukturiertheit gut dazu semantisch aufbereitet und als Linked Data publiziert zu werden. Bibliotheken erhoffen sich dadurch eine bessere Auffindbarkeit im Web und somit eine bessere Nutzung ihrer Dienstleistungen durch die Anwenderinnen und Anwender. Derzeit existieren nur wenige Webapplikationen, die diese semantisch aufbereiteten (bibliografischen) Informationen nutzen. In der vorliegenden Arbeit werden bestehende Linked Data Webapplikationen hinsichtlich Architektur, Workflows zum Nutzen der Daten und Userinterfaces untersucht. Darauf aufbauend wird ein Prototyp präsentiert, der bibliografische Daten unterschiedlicher Datenquellen explorativ zur Recherche und zur Navigation anbietet.
