wolframalphalogo_webWorld’s first Computational Knowledge Engine is one of the most eagerly anticipated international product launches of 2009.

Champaign, IL, May 18, 2009–Wolfram Alpha LLC today announced the general availability of Wolfram|Alpha, the world’s first computational knowledge engine, offered for free on the web.

Wolfram|Alpha draws on scientist Stephen Wolfram’s groundbreaking work on Mathematica, the world’s leading technical computing software platform, and on the discoveries he published in his paradigm-shifting book, “A New Kind of Science.” Over 200,000 people from throughout the world have contacted the company to learn more about Wolfram|Alpha since news of the service first surfaced broadly in March.

The long-term goal of Wolfram|Alpha is to make all systematic knowledge immediately computable and accessible to everyone. Wolfram|Alpha draws on multiple terabytes of curated data and synthesizes it into entirely new combinations and presentations. The service answers questions, solves equations, cross-references data types, projects future behaviors, and more. Wolfram|Alpha’s examples pages and gallery show a few of the many uses of this new technology.

“Fifty years ago,” said Stephen Wolfram, the founder and CEO of Wolfram Research, “when computers were young, people assumed that they’d be able to ask a computer any factual question, and have it compute the answer. I’m happy to say that we’ve successfully built a system that delivers knowledge from a simple input field, giving access to a huge system, with trillions of pieces of curated data and millions of lines of algorithms. Wolfram|Alpha signals a new paradigm for using computers and the web.”

Four Pillars of Wolfram|Alpha

Wolfram|Alpha is made up of four main “pillars” or components:

* Curated Data. Wolfram|Alpha contains terabytes of factual data covering a wide range of fields. Teams of subject-matter experts and researchers collect and curate data, transforming it into computable forms that can be understood and operated on by computer algorithms.

* Dynamic Computation. When Wolfram|Alpha receives a user query, it extracts the relevant facts from its stored computable data and then applies a collection of tens of thousands of algorithms, creating and synthesizing new relevant knowledge.

* Intuitive Language Understanding. To allow Wolfram|Alpha to understand inputs entered in everyday language, its developers examine the ways people express ideas within fields and subject matters and continually refine algorithms that automatically recognize these patterns.

* Computational Aesthetics. Wolfram|Alpha also represents a new approach to user-interface design. The service takes user inputs and builds a customized page of clearly and usefully presented computed knowledge.

Wolfram|Alpha has been entirely developed and deployed using Wolfram Research Inc’s Mathematica technology. Wolfram|Alpha contains nearly six million lines of Mathematica code, authored and maintained in Wolfram Workbench. In its launch configuration, Wolfram|Alpha is running Mathematica on about 10,000 processor cores distributed among five colocation facilities, using gridMathematica-based parallelism. And every query that comes into the system is served with webMathematica.

“Wolfram|Alpha is an extremely powerful way of harnessing the world’s knowledge. Now, anyone with web access can tap into that knowledge to find relevant information and discover new insights,” said Theodore Gray, co-founder of Wolfram Research.

The Wolfram|Alpha launch process has been broadcast live on Justin.tv and documented on the Wolfram|Alpha blog and on its Twitter and Facebook accounts. The site first went live for testing on Friday, May 15, 2009, and has been rigorously tested and further performance-tuned since then in preparation for
today’s official launch.
