- Abstract
- Der Artikel geht der Frage nach, ob und inwieweit Informations- und Recherchesysteme von der Technologie natürlich sprachlicher Frage-Antwortsysteme, so genannter Question Answering-Systeme, profitieren können. Nach einer allgemeinen Einführung in die Zielsetzung und die historische Entwicklung dieses Sonderzweigs der maschinellen Sprachverarbeitung werden dessen Abgrenzung von herkömmlichen Retrieval- und Extraktionsverfahren erläutert und die besondere Struktur von Question Answering-Systemen sowie einzelne Evaluierungsinitiativen aufgezeichnet. Zudem werden konkrete Anwendungsfelder im Bibliothekswesen vorgestellt.
