Title
Evaluation von Methoden und Methodologien zur Entwicklung von Ontologien und Entwurf einer Ontologie für den Lehrveranstaltungsbereich
Year
2005
Abstract
Ontologien sind explizite formale Beschreibungen von Konzepten und Relationen. Sie geben zusätzliche Beschreibungsinformationen auf einer Metaebene zu Daten eines bestimmten Sachbereichs. Solche Semantiken werden in der Informationstechnologie zunehmend nachgefragt. In dieser Diplomarbeit werden in einem analytisch-theoretischen Teil unterschiedliche Vorgehensweisen zur Entwicklung von Ontologien vorgestellt und evaluiert. Die Evaluation stellt dem Ontologieentwickler Entscheidungsgrundlagen bei der Auswahl einer geeigneten Vorgehensweise zur Verfügung. In einem praktischen Teil wird die Vorgehensweise METHONTOLOGY - in Verbindung mit der Ontologiesprache OWL und dem Entwicklungswerkzeug Protégé - angewendet, um eine Ontologie für den universitären Lehrveranstaltungsbereich zu entwickeln. Diese Ontologie soll später innerhalb des Projektes SIRUP (Semantic Integration Reflecting User-specific semantic Perspectives) eingesetzt werden. Im Rahmen dieser Diplomarbeit werden zwei Ziele angestrebt. Es wird eine Evaluation von ausgewählten Ontologieentwicklungsansätzen durchgeführt, die in der Fachliteratur beschrieben werden. Diese Evaluation dient dem Entwickler als Basis für die Auswahl der geeigneten Vorgehensweise anhand von gegebenen Anforderungen. Zudem ist diese Evaluation eine Hilfestellung für zukünftige Anwender von Ontologien. Ein weiteres Ziel ist die Erstellung einer Ontologie für den Lehrveranstaltungsbereich einer Universität. Diese Ontologie wird zu einem späteren Zeitpunkt innerhalb des Projektes SIRUP eingesetzt werden. Die Auswahl der Vorgehensweise zur Entwicklung dieser spezifischen Ontologie soll unter Einbezug der Erkenntnisse aus der Evaluation erfolgen. Das Auswahlverfahren erlaubt zugleich die Praxistauglichkeit der erarbeiteten Evaluation zu prüfen.
