    Abstract
    Das Exzellenzcluster Kognitive Interaktionstechnologie (CITEC) an der Universität Bielefeld beschäftigt sich seit 2013 mit der virtuellen Realität (VR). Ausgehend von konkreten Projektkooperationen (Publikations- und Forschungsdatenmanagement) mit der Universitätsbibliothek ist die Idee entstanden, mit der in 2016 neu angebotenen Konsumer-VR-Hardware die im Labor entwickelten Interaktionstechniken auf geeignete Szenarien im Bereich von bibliothekarischen Umgebungen anzuwenden. Als interessantes Anwendungsgebiet kristallisierte sich im gemeinsamen Diskurs die Literatursuche heraus: Als Suchsystem wurde die Bielefelder BASE-Datenbank (d.i. Bielefeld Academic Search Engine mit inzwischen mehr als 100 Mio. indexierten Dokumenten) ausgewählt. Diese Auswahl erfolgte vor dem Hintergrund, dass sich die von zahlreichen externen Institutionen bereits genutzte API-Schnittstelle als universell und robust erwiesen hat und umfangreiche Funktionen bereitstellt. Auf der Grundlage der umfangreichen theoretischen und praktischen Erfahrungen des CITEC mit VRTechniken wurde der Prototyp für eine virtuelle Suchumgebung realisiert, der ein Retrieval in einem Suchraum von Online-Dokumenten erlaubt. Die Nutzerinnen und Nutzer können die Suchanfrage explorativ zusammenstellen und dabei die Ergebnisse intuitiv verwalten. Unterstützt werden sie dabei durch Ergebnisanzeige, Sortierung, Optimierung des Suchergebnisses mittels Suchverfeinerung (Drilldown-basiert) oder Anfrageerweiterung und Wiederverwendung von abgelegten Ergebnissen. Gleichzeitig wird der Zugriff- und Lizenzstatus visualisiert und die Detailanzeige der Metadaten des Objektes integriert.

    Abstract
    Beschäftigt man sich mit Inhaltserschließung, so sind zunächst zwei Dimensionen zu unterscheiden - die Wissensorganisationssysteme selbst (z. B. Normdateien, Thesauri, Schlagwortsprachen, Klassifikationen und Ontologien) und die Metadaten für Dokumente, die mit diesen Wissensorganisationssystemen erschlossen sind. Beides steht in einer Wechselwirkung zueinander: Die Wissensorganisationssysteme sind die Werkzeuge für die Erschließungsarbeit und bilden die Grundlage für die Erstellung konkreter Erschließungsmetadaten. Die praktische Anwendung der Wissensorganisationssysteme in der Erschließung wiederum ist die Basis für deren Pflege und Weiterentwicklung. Zugleich haben Wissensorganisationssysteme auch einen Eigenwert unabhängig von den Erschließungsmetadaten für einzelne Dokumente, indem sie bestimmte Bereiche von Welt- oder Fachwissen modellartig abbilden. Will man nun Aussagen über die Qualität von inhaltlicher Erschließung treffen, so genügt es nicht, den Input - also die Wissensorganisationssysteme und die damit generierten Metadaten - zu betrachten. Man muss auch den Output betrachten, also das, was die Recherchewerkzeuge daraus machen und was folglich bei den Nutzer:innen konkret ankommt. Im vorliegenden Beitrag werden Überlegungen zur Qualität von Recherchewerkzeugen in diesem Bereich angestellt - gewissermaßen als Fortsetzung und Vertiefung der dazu im Thesenpapier des Expertenteams RDA-Anwendungsprofil für die verbale Inhaltserschließung (ET RAVI) gegebenen Hinweise. Im Zentrum steht die verbale Erschließung nach den Regeln für die Schlagwortkatalogisierung (RSWK), wie sie sich in Bibliothekskatalogen manifestiert - gleich, ob es sich dabei um herkömmliche Kataloge oder um Resource-Discovery-Systeme (RDS) handelt.
