Abstract
FOCUS: Viele Menschen sind frustriert, weil sie im Internet vergebens suchen. Warum versagen Suchmaschinen so häufig? Henzinger: Gerade Netz-Neulinge formulieren Suchbegriffe falsch, fragen zu allgemein oder zu speziell. Suchmaschinen haben Schwierigkeiten, aus einem oder zwei Wörtern die Gedanken eines Nutzers abzulesen. FOCUS: Google könnte dennoch Einsteigern bei der Suche mehr helfen ... Henzinger: ... indem wir aus den täglich 150 Millionen Suchanfragen Rückschlüsse ziehen, richtig. In Zukunft könnte die Software den Nutzer fragen: Du hast "BMW" eingegeben, willst du einen Wagen kaufen, mieten oder etwas über die Technik erfahren? FOCUS: Noch allerdings muss man sich durch lange Ergebnislisten wühlen. Henzinger. Suchmaschinen können heute eine Website zwar nach einem bestimmten Wort durchsuchen, aber nicht den Sinn verstehen. In dieser Hinsicht hinkt die Entwicklung den Anforderungen der Nutzer hinterher. FOCUS: Was unternehmen Sie dagegen? Henzinger: Wir arbeiten zum Beispiel verstärkt daran, zueinander in Beziehung stehende Internet-Seiten in eine Themen-Schublade zu stecken. Die Gefahr ist jedoch, dass Homepage-Betreiber das System unterlaufen, um weit oben auf der Ergebnisliste zu landen. FOCUS: Was anscheinend schon oft passiert ist, denn Google gerät wie andere Dienste immer wieder in die Schlagzeilen, weil Suchergebnisse von außen manipuliert wurden. Henzinger: Wu beobachten eine Art Wettrüsten: Unsere Programmierer entwickeln immer kompliziertere Aufspürmechanismen; kommerzielle Anbieter versuchen, diese zu knacken. Die Pornobranche trickst am raffiniertesten. FOCUS: Auf welche Weise? Henzinger. Sie versucht etwa, unseren elektronischen Spürhund auf eine falsche Fährte zu locken: Wird der GoogleSuchroboter identifiziert, zeigen ihm Sexanbieter eine völlig harmlose Homepage an. Wenn unsere Nutzer aber später diese Seite aufrufen, landen sie auf einer Pornoseite. Es kostet uns viel Geld, diese ständigen Attacken abzuwehren. FOCUS: Auch das so genannte "unsichtbare Web"ist für Sie ein Problem. Laut Experten soll dieses 500-mal größer sein als die vergleichsweise mickrigen zwei Milliarden Websites, die die digitalen Schnüffelverfahren heutzutage erfassen können. Henzinger: Es ist bislang schwer, zum Beispiel auf wissenschaftliche Datenbanken zuzugreifen. Deren Betreiber sind aber dabei, eine Brücke zwischen Suchprogrammen und Archiven zu schlagen. Parallel dazu arbeitet Google - ähnlich wie Spezial-Dienstleister - an Mechanismen, die bei bestimmten Anfragen nur passende Quellen zum Thema durchforsten. In fünf bis zehn Jahren wird das Netz viel weiter erschlossen sein. Intelligente Suchdienste werden dann auf eine Frage nicht mehr eine Website, sondern eine im Internet recherchierte Antwort auswerfen.
