A Plethora Of Piñatas
I'm excited. Geeking out, to be precise.
It started with this article, Wolfram Alpha — it’s like plugging into an electronic brain:
Scientist Stephen Wolfram has built a new engine, called Wolfram Alpha, that apparently can compute answers to factual questions more powerfully than Google.
Wolfram has just posted about the effort, which has taken years of working in stealth, and involves more than a hundred workers. He explains the basics of how his "computational knowledge engine" works: You ask it factual questions (such as "How many protons are in a hydrogen atom?") and it computes answers for you.
Many details about the engine, scheduled to launch in May, have yet to be released. However, Wolfram has shown the engine to search engine expert Nova Spivack. In a long post, Spivack calls the effort "almost absurdly ambitious" but concludes that it works, and claims that the engine has the potential to touch our lives as deeply as Google.
From Wolfram's blog:
Fifty years ago, when computers were young, people assumed that they’d quickly be able to handle all these kinds of things.
And that one would be able to ask a computer any factual question, and have it compute the answer.
But it didn’t work out that way. Computers have been able to do many remarkable and unexpected things. But not that.
I’d always thought, though, that eventually it should be possible. And a few years ago, I realized that I was finally in a position to try to do it.
...
It’s certainly the most complex project I’ve ever undertaken. Involving far more kinds of expertise—and more moving parts—than I’ve ever had to assemble before.
And—like Mathematica, or NKS—the project will never be finished.
But I’m happy to say that we’ve almost reached the point where we feel we can expose the first part of it.
It’s going to be a website: www.wolframalpha.com. With one simple input field that gives access to a huge system, with trillions of pieces of curated data and millions of lines of algorithms.
We’re all working very hard right now to get Wolfram|Alpha ready to go live.
I think it’s going to be pretty exciting. A new paradigm for using computers and the web.
That almost gets us to what people thought computers would be able to do 50 years ago!
And finally the peice by Nova Spivack, Wolfram Alpha is Coming -- and It Could be as Important as Google:
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 country is Timbuktu in?" or "How many protons are in a hydrogen atom?" or "What is the average rainfall in Seattle this month?," "What is the 300th digit of Pi?," "where is the ISS?" or "When was GOOG worth more than $300?"
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.
...
Wolfram Alpha is like plugging into a vast electronic brain. It provides extremely impressive and thorough answers to a wide range of questions asked in many different ways, and it computes answers, it doesn't merely look them up in a big database.
In this respect it is vastly smarter than (and different from) Google. Google simply retrieves documents based on keyword searches. Google doesn't understand the question or the answer, and doesn't compute answers based on models of various fields of human knowledge.
But as intelligent as it seems, Wolfram Alpha is not HAL 9000, and it wasn't intended to be. It doesn't have a sense of self or opinions or feelings. It's not artificial intelligence in the sense of being a simulation of a human mind. Instead, it is a system that has been engineered to provide really rich knowledge about human knowledge -- it's a very powerful calculator that doesn't just work for math problems -- it works for many other kinds of questions that have unambiguous (computable) answers.
There is no risk of Wolfram Alpha becoming too smart, or taking over the world. It's good at answering factual questions; it's a computing machine, a tool -- not a mind.
One of the most surprising aspects of this project is that Wolfram has been able to keep it secret for so long. I say this because it is a monumental effort (and achievement) and almost absurdly ambitious. The project involves more than a hundred people working in stealth to create a vast system of reusable, computable knowledge, from terabytes of raw data, statistics, algorithms, data feeds, and expertise. But he appears to have done it, and kept it quiet for a long time while it was being developed.
Did I mention that I was geeking out?
