- Abstract
- Es werden die Grundprobleme der Sacherschließung in Online-Katalogen dargestellt. Ein anschließendes Kapitel behandelt das Verhältnis von verbaler und klassifikatorischer Erschließung. Ein wichtiger Teil der Aussagen betrifft das Gebiet der verbalen Sacherschließung und damit das nationale Regelwerk: Es werden Vorschläge für eine Reform der RSWK im Hinblick auf die Erfordernisse der OPAC unterbreitet. Regelwerk und Normdatei (SWD) bilden dabei eine Einheit und werden zusammen betrachtet. Im vergangenen Jahr wurden die Ergebnisse der Expertengruppe mit dem Schwerpunkt Formalerschließung vorgelegt, nun folgen die Aussagen zur Sacherschließung, welche die Expertengruppe - in veränderter personeller Zusammensetzung unter Leitung von Dr. Friedrich Geißelmann, Regensburg - erarbeitet hat. Die bibliothekarische Öffentlichkeit ist aufgefordert, sich dazu bis zum Jahresende zu äußern. Beide Berichte beziehen sich aufeinander und versuchen, den Zusammenhang zwischen Formal- und Sacherschließung herzustellen. Vom gegenwärtigen Stand der Sacherschließung in deutschen Bibliotheken ausgehend - wozu auch durch die Gruppe im Frühjahr 1993 eine Umfrage in wissenschaftlichen und Öffentlichen Bibliotheken gemacht worden ist, werden die Grundprobleme der Sacherschließung in Online-Katalogen dargestellt. Ein anschließendes Kapitel behandelt das Verhältnis von verbaler und klassifikatorischer Erschließung. Ein wichtiger Teil der Aussagen betrifft das Gebiet der verbalen Sacherschließung und damit das nationale Regelwerk: Es werden Vorschläge für ein Reform der RSWK im Hinblick auf die Erfordernisse des OPAC unterbreitet. Regelwerk und Normdatei (SWD) bilden dabei eine Einheit und werden zusammen betrachtet. Es geht um Kettenbildung und Permutationsregeln, Kompositumbildung oder Zerlegung von Begriffen, Pleonasmus, Funktion der SWD, Ansetzung von Schlagwörtern, die Einführung eines Zeit-Codes, Erschließung literarischer Formen und Gattungen, den verwendeten Zeichensatz, den Umgang mit Verweisungen

- Abstract
- Die Diskussion um Vor- und Nachteile von Präkoordination oder Postkoordination wird unter den in der verbalen Sacherschließung Engagierten in Deutschland seit Jahren geführt. Mit zunehmender Verbreitung der RSWK gewinnen die Überlegungen, die sich angesichts der Ausbreitung des OPAC für das 'Zerschlagen' der Schlagwortketten aussprechen, an Bedeutung. In diesem Zusammenhang trägt eine Berücksichtigung der internationalen Debatte um Prä- und Postkoordination zur Erweiterung des nationalen Horizontes bei. Der Beitrag ist eine leicht gekürzte Übersetzung eines Referates, das die Autorin beim IFLA Satellite Meeting zum Thema 'Subject indexing in the 90's - principles and practices' im August 1993 in Lissabon gehalten hat

- 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
- Die Kombination von gleichzeitig mehreren oder vielen intellektuell konstruierten Thesauri und maschineller Indexierung der Texte führt zu einer umfassenderen und spezifischeren Beschreibung von Dokumenten als die intellektuelle Klassifizierung oder die Indexierung allein. Durch die Expansion der Suchfrage um Thesauruseinträge wird der recall deutlich erhöht. Zugleich kann die intellektuelle Klassifizierung in überschaubaren Domänen dazu genutzt werden, baumartig in Dokumentenkollektionen zu navigieren oder die Suche erst in Teilbereichen der Klassifikation zu beginnen, um die precision zu erhöhen. Der Einsatz von Thesauruskollektionen wird an den Beispielen dandelon.com, Landtagsinformationssystem Vorarlberg und der Landeshomepage vorarlberg.at dargestellt.
