Abstract

Über die Heterogenität der Sacherschließung in der deutschen Bibliothekslandschaft ist schon viel berichtet und geschrieben worden. Im Folgenden wird dargestellt, wie eine Suchumgebung ausgehend von der DDC aufgebaut werden kann und wie diese auf andere Erschließungssysteme erweitert werden kann. ... Fazit: Navigation ausgehend von der DDC Als das weltweit am meisten benutzte Klassifikationssystem hat die DDC ein erhebliches Potential, sich als Switching Language für sprachunabhängige Dokumentenrecherche zu positionieren. Allerdings ist eine verbale Suche für viele Benutzer deutlich intuitiver, so dass der Umstieg auf rein hierarchisches Browsing - wie es die DDC erlauben würde - nicht sinnvoll erscheint. Angesichts der großen Zahl an vorhandenen, mit SWD erschlossenen Daten wäre eine solche Vorgehensweise unsinnig. Vielmehr müssen die Bestrebungen darauf konzentriert werden, das Nebeneinander der verschiedenen Erschließungsmethoden auf der Ebene der Suchmaschinen zusammen zu führen. Für die wissenschaftliche Literaturrecherche birgt die Möglichkeit zur verteilten Suche über heterogen erschlossene Daten ein großes Potential. Die obigen Überlegungen stellen die Vorgehensweise dar, wie dies im Projekt DDC Deutsch verfolgt und realisiert wird.
