Abstract
Für eine fiktive Dokumentmenge wird eine Dokument-Wort-Matrix erstellt und mittels zweier Suchanfragen, ebenfalls als Matrix dargestellt, die Retrievalergebnisse ermittelt. Den Wörtern der Dokumentmenge werden in einem zweiten Schritt Aspekte zugeordnet und die Untersuchung erneut durchgeführt. Ein Vergleich bestätigt die schon früher gefundenen Vorteile des aspektischen Indexierung gegenüber anderen Methoden der Retrievalverbesserung, wie Trunkierung und Controlled Terms
Theme
Indexierungsstudien
