    Abstract
    Folgender Beitrag beschäftigt sich mit der Konzeption und Durchführung von nachhaltigen Evaluationen von Information Retrieval Systemen mit Visualisierungskomponenten. Bisherige Evaluationsansätze differieren sowohl in der Methodenauswahl als auch Untersuchungsanlage, wie eine State-of-the-Art-Analyse aufzeigt. Im Anschluss werden die größten Herausforderungen, die sich bei Evaluationen dieser Art ergeben mit Vorschlägen zu potenziellen Lösungsansätzen diskutiert. Auf der Grundlage eines morphologischen Rahmens wird ein Bezugsrahmen für die Evaluation von Information Retrieval Systemen mit Visualisierungskomponenten vorgeschlagen, das einen integrierten Ansatz zur Kombination geeigneter Methoden aus dem Bereich der Usability-Evaluation und der Retrievaleffektivitäts-Evaluation verfolgt.

    Abstract
    Maschinelles Indexieren vereinheitlicht und vermehrt das Suchvokabular eines Bibliothekskatalogs durch verschiedene Methoden (u.a. Ermittlung der Grundform, Kompositazerlegung, Wortableitungen). Ein Retrievaltest mit einem für öffentliche Bibliotheken typischen Sachbuchbestand zeigt, dass dieses Verfahren die Ergebnisse von OPAC-Recherchen verbessert - trotz 'blumiger' Titelformulierungen. Im Vergleich zu herkömmlichen Erschließungsmethoden (Stich- und Schlagwörter) werden mehr relevante Titel gefunden, ohne gleichzeitig den 'Ballast' zu erhöhen. Das maschinelle Indexieren kann die Verschlagwortung jedoch nicht ersetzen, sondern nur ergänzen

    Abstract
    Anhand eines einfachen Modells wird geprüft, ob der Nutzen den Aufbau einer Spezialsuchmaschine trägt. Zum Vergleich werden fünf große Suchmaschinen herangezogen und deren Ergebnisse bei gleichen Fragestellungen analysiert. Es ergeben sich gravierende Abweichungen sowohl in der Überdeckung der Ergebnismengen als auch im Ranking. Es erscheint also sinnvoll, eine eigene Suchmaschine zu betreiben
