In Password 11/2000 wurden durch einen Retrievaltest die qualitativ führenden Suchwerkzeuge im Internet bestimmt. In den nächsten Teilen unseres State of the Art - Berichts über Retrievalsysteme im World Wide Weh beschreiben wir einzelne interessante Ansätze der Technik der TopSuchwerkzeuge. Den Anfang machen die klassifikatorischen Verzeichnisse Yahoo! und das Open Directory-Projekt sowie das System Oingo, das im Rahmen eines "semantischen Retrievals" das Homonym- und Synonymproblem angeht
