Abstract
Die Schlagwortnormdatei (SWD) ist mit einem Umfang von ca. 150.000 Sachschlagwörtern das umfangreichste terminologisch kontrollierte deutschsprachige Vokabular, das zur verbalen Inhaltserschließung von Dokumenten genutzt werden und somit prinzipiell auch als Kandidat für den Aufbau semantischer Navigationsstrukturen im Online-Retrieval angesehen werden kann. Die Strukturierung der Schlagwörter in der SWD folgt den Vorgaben zur Ausweisung begrifflicher Strukturen in einem Thesaurus. Durch Veränderungen des der Erstellung der SWD zu Grunde liegenden Regelwerkes RSWK hat sich im Verlauf der Zeit ein Nebeneinander von unterschiedlich dichten Beziehungsnetzen ergeben, ohne dass hierzu bislang Details erhoben und dokumentiert wären. In dieser Studie werden Aussagen über den Aufwand gemacht, der erforderlich wäre, die semantische Relationenstruktur der Schlagwortnormdatei (SWD) zu homogenisieren. Hierzu wird eine quantitative und qualitative Analyse am Beispiel mehrerer Themengebiete vorgenommen. Die Berücksichtigung mehrerer Gebiete soll es gestatten, möglichst repräsentative Aussagen für das gesamte Vokabular abzuleiten. Die Autorinnen und Autoren der Studien sind sich angesichts der zur Verfügung stehenden begrenzten Ressourcen bewusst, dass dieser Anspruch nur mit Einschränkungen eingelöst werden kann. Die für die Analyse der Relationenstruktur benutzten Kriterien orientieren sich an Grundsätzen zur Gestaltung strukturierten Vokabulars sowie insbesondere der Eignung der SWD, zum Aufbau bestandsunabhängiger semantischer Navigationssysteme im Online-Retrieval, für Zwecke des wörterbuchgestützten automatischen Indexierens.
Mit diesem Kriterium lässt es sich nicht vermeiden, dass Relationen als fehlend charakterisiert werden, auch wenn sie vom Regelwerk nicht gefordert werden. Die Analysen berücksichtigen allerdings die Verzahnung der SWD zum Regelwerk RSWK insoweit, als in der Regel nur bereits vorhandene Schlagwörter betrachtet wurden und nicht auch Lücken analysiert wurden, die allein deswegen vorhandenen sind, weil Schlagwörter wegen nicht vorhandener Bücher (noch) nicht gebildet wurden. Die Funktion der SWD zur terminologischen Ansetzung von Schlagwörtern ist nicht Gegenstand der Studie. Der Bericht dokumentiert zusätzlich Inkonsistenzen, die während der Analysen ermittelt wurden. Ziel dieses Projekts ist es, die tatsächlich erreichte Situation der Relationenstruktur der SWD zu ermitteln sowie Vorschläge auszuarbeiten, an welchen Stellen eine Nachbearbeitung der Relationen erfolgen sollte und wie dies realisiert werden könnte. Bei dieser Analyse wird nicht differenziert zwischen Relationierungen, die vom Regelwerk RSWK gedeckt sind und Relationierungen, die allgemeinen Regeln zur Darstellung begrifflicher Strukturen entsprechen.
