From the FAQ page at Wolfram|alpha (the service is some 20 years old!):
"Does Wolfram|Alpha use artificial intelligence?
Not in a traditional sense. Wolfram|Alpha isn't mainly based on emulating human reasoning. Instead it uses powerful methods from science and algorithmic computation to get directly to answers."
"Is Wolfram|Alpha an artificial intelligence?
"It's much more an engineered artifact than a humanlike artificial intelligence. Some of what it does—especially in language understanding—may be similar to what humans do. But its primary objective is to do directed computations, not to act as a general intelligence."
