Abstract

In der Informationswissenschaft stehen Thesauri für kontrollierte und strukturierte Vokabulare, in denen Begriffe, verstanden als geistige Einheiten, durch Bezeichnungen der natürlichen Sprache repräsentiert werden. Jedem Begriff werden eine Vorzugsbenennung, ein sog. Deskriptor, der bei der Inhaltserschließung als Schlagwort vergeben wird, und weitere bedeutungsgleiche oder -ähnliche Bezeichnungen, sog. Nicht-Deskriptoren, als Zugangsvokabular bzw. alternative Sucheinstiege zugewiesen. Dieser Art werden der Variabilität und der Mehrdeutigkeit natürlicher Sprache Rechnung getragen. Darüber hinaus werden zwischen Begriffen bzw. ihren Bezeichnungen spezifische, reziproke Relationen kenntlich gemacht (s. Abschnitt 1), die die Bedeutungsbeziehungen bzw. das "semantische Gefüge" zwischen den Begriffen aufzeigen. Diese Kernprinzipien dieser Wissensorganisationsmethode dienen sowohl auf Seiten der Inhaltserschließenden als auch auf Seiten der in einem Informationssystem Recherchierenden in unterschiedlicher Weise der Benutzerführung und Suchunterstützung. Als Grundlage für semantisches Retrieval etwa sorgen sie bei automatischer Erweiterung der Suchanfrage um die hinterlegten Nicht-Deskriptoren für eine erfolgreiche Suche weitgehend unabhängig vom konkreten Suchterm.
