Abstract

Diese Arbeit untersucht, wie sich eine Forschungskontext-Ontologie als Quelle für die Generierung von Query-Expansion-Termen in einem Retrievalsystem für die Domäne der Erziehungswissenschaft nutzen lässt. Durch die Kombination traditioneller, groß angelegter automatischer Retrievalexperimente und nutzerzentrierter interaktiver Retievalexperimente wird ein umfassendes Bild der Effekte ontologiebasierter Query Expansion gezeichnet. Während die automatischen Experimente die Expansionseffekte einzelner Arten ontologiebasierter Expansionsterme im Detail untersuchen, beleuchten die interaktiven Experimente, wie ontologiebasierte Expansionsmechanismen das Suchverhalten der Nutzer sowie ihren Sucherfolg beeinflussen.
