Abstract
Wie die Geschichte des Science Citation Index (SCI) zeigt, hat sich im wissenschaftlichen Information Retrieval die Nutzung von Zitationsbezügen zwischen Texten als wohl erfolgreichste Ergänzung traditioneller, begriffsorientierter Erschließungsmethoden erwiesen. Dieser Erfolg läßt sich durch neuere Experimente bestätigen, die Recall und Precision Boolescher Begriffssuchen mit zitationsgestützten Suchen in Online-Datenbanken vergleichen. Mit Hilfe zitationsgestützter Suche lassen sich in der Regel zusätzliche relevante Dokumente nachweisen, wobei die Schnittmenge der mit den beiden Methoden erhaltenen Dokumente stets gering ist. Aus einer Reihe von Beobachtungen richterlichen Zitierverhaltens anhand von Dokumenten des 'Juristischen Informationssystems für die Bundesrepublik Deutschland' (Juris) läßt sich folgern, daß auch das Retrieval von Urteilsdokumenten durch Berücksichtigung von Zitationsbezügen zwischen Urteilen verbessert werden kann. Diese Verbesserung sollte sich vor allem der Methoden des 'bibliographic coupling' und der Kozitationsanalyse bedienen (analog zu entsprechenden Verfahren des SCI auf CD-ROM-Datenträgern). Voraussetzung hierfür ist, daß die 'Juris'-Praxis, in Urteilen des Finanz- und Abgabenrechts Zitate vollständig nachzuweisen, auf alle Rechtsgebiete ausgedehnt wird
