Abstract: Die deutschen Suchmaschinen, Abacho, Acoon, Fireball und Lycos sowie die Web-Kataloge Web.de und Yahoo! werden einem Qualitätstest nach relativem Recall, Precision und Availability unterzogen. Die Methoden der Retrievaltests werden vorgestellt. Im Durchschnitt werden bei einem Cut-Off-Wert von 25 ein Recall von rund 22%, eine Precision von knapp 19% und eine Verfügbarkeit von 24% erreicht

- Karte mit bunten Kreisen - Während Vivisimo noch eine klassische MetaSuchmaschine ist, ist Grokker (www.groxis. com) ein Programm des kalifornischen Softwareunternehmens Groxis, schon optisch eine Innovation. Es sortiert die Suchergebnisse nicht nur, sondern visualisiert-die Kategorien als Karte mit bunten Kreisen. Innerhalb eines solchen Kreises gibt es Unterkategorien, also kleinere Kreise, die angeklickt werden können. Allerdings dauert es ein wenig, bis man sich damit zurechtfindet. Ein einfaches Beispiel verdeutlicht den Unterschied zu herkömmlichen Suchmaschinen. Bei den Schlagworten "Paris Hilton" erhält man etwa bei Google einerseits Treffer aus der Kategorie Reisen und Unterkünfte andererseits aber auch jede Menge Seiten, auf denen die Hotelerbin Paris Hilton erwähnt ist. Denn Google sortiert die Fundstellen danach wie viele Links zur jeweiligen Seite führen. Dem Nutzer bleibt die Arbeit, die lange Liste zu durchforsten: Nicht so bei Grokker oder Vivisimo: Hier werden die Ergebnisse nach Themengebieten gruppiert. Grokker selbst ist aber keine Suchmaschine, sondern kombiniert die Resultate von Yahoo, MSN, AltaVista, Wisenut, Teoma und FAST. Das Programm kann auch Dateien auf der Festplatte kategorisieren. Wir sind jetzt in der Lage, alles zu 'grokken'" sagt Groxis-Chef R. J. Pittman. Auch mit Google stehe man in Verhandlungen. Anders als bei Vivisimo gibt es von Grokker keine deutsche Version. Und außerdem ist das Programm nicht gratis: Die Vollversion kostet 49,95 Dollar, eine kostenlose Testversion für 30 Tage kann nach Anmeldung heruntergeladen werden. Eine andere Form der Visualisierung von Suchergebnissen hat www.touchgraph.com entwickelt. Die Firma bietet mit dem TouchGraph Google Browser ein Applet an, das die Fundstellen als Netzstruktur, als Beziehungsgeflecht veranschaulicht. Basis dafür ist die GoogleFunktion "Ähnliche Seiten". Die dokumentierten Verknüpfungen zwischen den verschiedenen Internetseiten werden grafisch dargestellt."
