Abstract
Die Arbeit entwirft ein Konzept für eine Simulation, die als Teil eines ELearning-Moduls die Probleme der automatischen Freitextindexierung und linguistische Verfahren zur Verbesserung der Indexierungsergebnisse veranschaulichen soll. Zielgruppe der Simulation sind die im Studierenden des Fachbereichs Bibliothek und Information der HAW Hamburg, die sich im Grundstudium befinden. Es wird ein inhaltliches Konzept dafür entwickelt, wie die Simulation Vor- und Nachteile regelbasierter und wörterbuchbasierte Indexierungsverfahren für das Grundstudium darstellen kann. Ziel ist zu zeigen, dass regelbasierte Verfahren in einer stark flektierenden und kompositareichen Sprache wie dem Deutschen zu zahlreichen Indexierungsfehlern führen können und dass wörterbuchbasierte Verfahren bessere Indexate liefern. Im zweiten Teil der Arbeit wird eine Informationsarchitektur für die Simulation entworfen und ein Prototyp programmiert, der eine Freitextindexierung und darauf aufbauend ein regelbasiertes Reduktionsverfahren darstellt. Ziel dabei ist insbesondere zu zeigen, dass regelbasierte Indexierungsverfahren für das Deutsche keine befriedigenden Ergebnisse erzielen, und dass wörterbuchbasierte Verfahren im Deutschen zu bevorzugen sind. Vor diesem Hintergrund wird im zweiten Teil der Arbeit ein Prototyp für die Simulation konzipiert, die elektronische Volltexte zunächst nach der Freitextmethode und danach mit linguistischen Verfahren indexiert. Es wird eine Informationsarchitektur entwickelt, die nicht nur anstrebt, der Zielgruppe gerecht zu werden, sondern auch die Vor- und Nachteile der linguistischen Indexierungsverfahren möglichst deutlich zu zeigen. Für die Freitextindexierung als einfachste Form der automatischen Indexierung und für das regelbasierte Verfahren wird auch schon der Programmcode geschrieben. Für die regelbasierte Wortformenreduktion greift die Autorin auf ein schon bestehendes Programm zurück, das Cornelie Ahlfeld 1995 im Rahmen ihrer Diplomarbeit entwickelt hat. Die Autorin versucht, dieses Programm durch eine Präsentation der Indexierungsergebnisse zu ergänzen, die es für den Einsatz in der Lehre nützlich machen.
