I am disappointed as my high hopes in Wolfram|Alpha were far from realized. I don’t want to say Alpha is useless because I am a computer science geek so I will give Alpha some time to try to recover and resolve the many challenges.
I intend to write a series of reviews, so this will be the first one of a few.
Alpha Test dates: May 15 – 16, 2009
(For a collection of other reviews, see this BBC link.)
Speed: Very slow. (May be “too slow”.)
I hope the speed will improve over time. But since Alpha is computing the answers on the fly, and not looking up from indexed answers, I understand it will take longer than Google. But it can’t be “too slow”. I hope Alpha will improve on this.
Stocks:
If you enter stock symbols or names of some publicly traded companies, Alpha will create a comparison for you. Generating pages of info when I asked it about RY TD [Royal Bank and TD] (try it).
Now, we can get most of the basic info from finance site like google and yahoo. I wonder if information like the following will be truly useful for investment decision making or will they be data/noise disguise as insight?
Correlation matrix
Mean-variance optimal portfolio
optimal portfolio’s expected yearly return | 6.31%
optimal portfolio’s yearly volatility | 8.37%
You see, I have trouble take the words in investment bank analysts’ reports without thinking about their implications carefully, you can imagine the trouble I have in the “black box” numbers Alpha generated.
Not understanding users’ questions.
“Wolfram|Alpha isn’t sure what to do with your input.”
May be this is the most important challenge Alpha has at the moment: its inability to understand simple English questions. The following are NOT tough questions at all.
Chinese population in Calgary?
How many words in the Bible?
How many people died in Cultural Revolution?
Numbers of lawyers in Calgary?
Seeing Alpha returns with “Wolfram|Alpha isn’t sure what to do with your input.” over and over and over again disappoints me to no end.
Concluding thoughts
As a computer geek (who actually had studied the Turing Test in school (smile)), I am loving what Stephen Wolfram is trying to achieve and I wish him and his team the best of luck. If I were a normal regular user, I would have to say I was very disappointed by Alpha.
Fortunately, I am a computer geek, I will come back on Monday and play with Alpha some more when it officially launches. And then some more later …
