Now that Wolfram Alpha is live, we can start to see if it fills a niche in our daily lives. When I used it, about half my queries were input that the engine did not understand. There were gaps I didn't expect. If it knows how tall a regular object is, like the Great Pyramid of Giza, why didn't someone input the length of the sides?
It did parse a question about the death of Bloody Mary, and gave me the right queen in English history.
Curiously, it know information that it doesn't seem to have connected. I asked how many ounces in a kilo of flour, and it didn't understand the input, but it gave me kilo of flour to click on. And at the very end, beyond the nutritional value of a kilo of flour, it said it had a mass of 35 ounces. It also had a serving volume of 58 fluid ounces. Now why didn't it connect those facts associated with kilo of flour with the question how many ounces in a kilo of flour?
So even within the information available on Wolfram|Alpha, there is a tendency to be too literal or straight line with its answers, and not make a web of connections. That is a problem in the way the engine works, not the information inside it.
