Abstract
Lernende Computersysteme überraschten zuletzt immer wieder mit bemerkenswerten Leistungen. Google-Forscher haben jetzt gezeigt, wie Maschinen Menschen selbst bei der Ortsbestimmung von Bildern übertreffen können. Suchen Sie sich im Web ein zufälliges Bild aus und versuchen Sie dann, ohne weitere Hilfsmittel herauszufinden, wo es aufgenommen wurde. Wenn das Bild ein berühmtes Gebäude oder eine andere Sehenswürdigkeit wie den Eiffelturm oder die Niagarafälle zeigt, mag das noch leicht sein. Kompliziert aber wird es, wenn es in dem Foto an konkreten Hinweisen über den Standort fehlt, wenn es nicht im Freien aufgenommen wurde oder wenn darauf nur ein Haustier, Essen oder ein anderes Objekt zu sehen ist. Trotzdem sind Menschen überraschend gut bei dieser Aufgabe. Um sie zu meistern, nutzen sie alle möglichen Arten von Weltwissen, etwa über Schrifttype oder Sprache auf Schildern, Vegetation, Architekturstile, Richtung des Verkehrs und so weiter. Menschen verbringen sozusagen ihr ganzes Leben damit, Hinweise zur Ortung aufzusammeln. Also könnte man meinen, dass sich Maschinen mit dieser Aufgabe weitaus schwerer tun. Bislang war das tatsächlich der Fall.
