A friend sent me the link to this interesting web game and I am pretty impressed with the results. I have played it a few times and I can see that it can become quite an addictive distraction. The batting average of the Akinator in my hands is pretty impressive so far. Here are some of the "characters" it identified for me and the number of questions it asked to find the correct answers.
Rabindranath Tagore - 18
Jawaharlal Nehru - 13
Aung San Suu Kyi -18
Emperor Akbar - 19
Shah of Iran - 18
Friedrich Nietzsche -20
Aristotle - 10
Obama - 7
Audrey Hepburn and Sophia Loren - 8 each
I played the game on the American site. It is quite natural that Asian figures took a bit longer than a recent American president and popular western film stars. (I haven't tried Indian movie stars or fictional characters yet) Also, it is not terribly surprising that Nietzsche needed double the number of questions than did Aristotle. Even the couple of mistakes it made were not illogical - Ferdinand Magellan for Vasco da Gama and Guru Gobind Singh for Shivaji. The accuracy of the Akinator of course depends on the depth of our own knowledge of the character we want it to identify. What amazed me somewhat is the totally random and superficial nature of the questions it asks and comes up with the correct answer.
Ask the Akinator and tell me how your real and fictional "characters" do in its hands. Just remember that they have to be somewhat well known.
