Stephen Wolfram may just be on to the next big thing on the internet. He and the boys and girls at Wolfram Research, Inc. are scheduled to launch Wolfram Alpha, a “computational knowledge engine” for the web. This engine is designed to “compute the answer to all factual questions”, questions the answer to which is an acknowledged fact. Examples are ‘What is the population of Berlin?’, ‘How much copper has Peru mined over the last 30 years?’, ‘Plot the spread of swine flu over the last three weeks.’, ‘Solve a*x^3 – b*x = 0.’.
WAlpha will complement the Google search service, which provides you with a whole bunch of links that may or not answer your question or relate to your keyword(s) input. The WAlpha service will actually parse (pick apart with understanding) your query, and then go through a computational inference process to develop the answer either through known relationships (like in physics) or access it from available “curated” knowledge bases. The system will, of course, grow and get smarter with the passage of time and continued use.
Some of you will recall that Dr. Wolfram is a celebrated systems scientist who recently wrote A New Kind of Science. In this thick book Wolfram argues that very complex systems, like perhaps the entire universe, really operate on a foundation of myriads of simple algorithms executing and interacting – fundamentally the universe is a big ongoing computation. The complex dynamic activity we see around us is nothing more than emergent properties as a result of the execution and interaction of very simple algorithms. The universe is (in?) a giant computer.
