Abstract
In den letzten Jahren haben neue technische Entwicklungen, insbesondere im Bereich der Speicherung großer Datenmangen, zu einer weiten Verbreitung von IR-Systemen geführt. Leider basieren aber fast alle derzeit auf dem Markt angebotenen Systeme noch auf der gleichen Konzeption, die bereits den Anfang der 70er Jahre verfügbaren Systemen zugrundelag. Fortschritte sind allenfalls im Bereich der Benutzerschnittstellen auszumachen, die aber die grundlegenden Schwächen der Systeme nur unzureichend kompensieren können. Unberücksichtigt bleiben dagegen wesentliche Ergebnisse der IR-Forschung, die z.B. belegen, daß durch Rankingmethoden in Kombination mit robusten linguistischen Erschließungsverfahren nicht nur die Retrievalqualität deutlich verbessert werden kann, sondern durch den Verzicht auf Boolesche Anfragesprachen auch die Bedienung des Systems wesentlich erleichtert wird
