Wolfram Alpha is Coming -- and It Could be as Important as Google | Twine
A Computational Knowledge Engine for the Web
In a nutshell, Wolfram and his team have built what he calls a "computational knowledge engine" for the Web. OK, so what
does that really mean? Basically it means that you can ask it factual questions and it computes answers for you.
It doesn't simply return documents that (might) contain the answers, like Google does, and it isn't just a giant
database of knowledge, like the Wikipedia. It doesn't simply parse natural language and then use that to retrieve
documents, like Powerset, for example.
Instead, Wolfram Alpha actually computes the answers to a wide range of questions -- like questions that have factual
answers such as "What is the location of Timbuktu?" or "How many protons are in a hydrogen atom?," "What was the average
rainfall in Boston last year?," "What is the 307th digit of Pi?," or "what would 80/20 vision look like?"
Think about that for a minute. It computes the answers. Wolfram Alpha doesn't simply contain huge amounts of manually
entered pairs of questions and answers, nor does it search for answers in a database of facts. Instead, it understands
and then computes answers to certain kinds of questions.
(Update: in fact, Wolfram Alpha doesn't merely answer questions, it also helps users to explore knowledge, data and
relationships between things. It can even open up new questions -- the "answers" it provides include computed data or
facts, plus relevant diagrams, graphs, and links to other related questions and sources. It also can be used to ask
questions that are new explorations between relationships, data sets or systems of knowledge. It does not just provides
textual answers to questions -- it helps you explore ideas and create new knowledge as well)
