- 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.

- Abstract
- Das Prinzip, zur Wiedergabe eines komplexen Gegenstands mehrere Schlagwörter in Form einer Schlagwortkette zu verknüpfen, gehört zum zentralen Kern der 'Regeln für den Schlagwortkatalog' (RSWK). Während die Bildung solcher Schlagwortketten - also der Input - umfassend geregelt ist, verzichtet das Regelwerk jedoch darauf, auch für den Output nähere Vorgaben zu machen: "Die Gestaltung des Retrievals von Schlagwörtern und ihrer Anzeige im Online-Katalog" sei "Aufgabe des jeweiligen OPACs", weshalb man sich auf "einzelne Hinweise" beschränke (§ 20,1). Explizit genannt werden immerhin die "Suche nach Schlagwortketten" und das Browsing im Schlagwortkettenindex (5 20,5). Freilich ist seit langem bekannt, dass Schlagwortketten in vielen OPACs recht 'stiefmütterlich' behandelt werden. Eine aussagekräftige Bestandsaufnahme über die tatsächliche Nutzung der Schlagwortketten in aktuellen OPACs fehlte jedoch. Eine solche hat die Verfasserin im Februar 2008 unternommen. Den Hintergrund dafür bildeten die Überlegungen der vom Standardisierungsausschuss eingesetzten Ad-hoc-Arbeitsgruppe "Strategie der Sacherschließung" unter dem Vorsitz von Dr. Friedrich Geißelmann (UB Regensburg). In diesem Rahmen wurde auch über Wege diskutiert, um das große Potenzial der Schlagwortketten besser für das Retrieval nutzbar zu machen. Für die Untersuchung wurden - ohne Anspruch auf Vollständigkeit - 40 Online-Kataloge mit Schlagwortkettenfunktionalitäten analysiert. Zehn unterschiedliche Katalogsysteme waren dabei vertreten: Aleph, Allegro, Biber, Bond, Horizon, Libero, PICA, SISIS-Sunrise, Urica und Virtua. Eine Liste der betrachteten OPACs inkl. ihrer URLs und der im Folgenden verwendeten Siglen ist im Anhang zu finden. Die Darstellung stellt zwangsläufig eine Momentaufnahme dar, denn die OPACs sind natürlich keine statischen Systeme: Schon bei Abfassung des vorliegenden Beitrags im Juli 2008 waren einige Änderungen einzuarbeiten, die sich seit Februar ergeben hatten; weitere Umgestaltungen der Kataloge sind nur eine Frage der Zeit. Desungeachtet gibt die Studie einen Überblick über derzeit implementierte Funktionalitäten sowie aktuelle Trends, und ermöglicht auch das Aufzeigen von Problemfeldern und Verbesserungsmöglichkeiten.
