Abstract
Der Kampf ist eröffnet: Als vergangene Woche der britische Physiker Stephen Wolfram erstmals der Öffentlichkeit die neue "Antwortmaschine" Wolfram Alpha vorstellte, kündigte Google einen eigenen neuen Dienst an. Wolfram Alpha greift auf Datenbanken zurück, die von Wolfram Research betrieben werden, und wendet auf ihre Inhalte Algorithmen an, um Antworten auf Fragen zu generieren, die Nutzer stellen. Mit dem vom Wolfram-Team vorab zur Verfügung gestellten Login machte ich die Probe aufs Exempel: Wolfram Alpha vs. Google (in der Standardform). Ich gab jeweils die gleichen Anfragen ein und variierte sie in einigen Fällen, um zu sehen, was passiert. Auf diese Weise wollte ich jenseits der allgemeineren Beschreibungen, die ich bei einem Besuch bei Wolfram Research bekommen hatte, einige reale Ergebnisse produzieren. Und natürlich den Anspruch der neuen Maschine überprüfen: Antworten aus Suchanfragen zu "berechnen". Hier ist das Ergebnis meines Tests. [06.06.2009]
