Wolfram|Alpha Officially Launches



Wolfram Alpha LLC, a spin-off of Wolfram Research, has officially announced the availability of Wolfram|Alpha, what the company calls "the world's first computational knowledge engine." Wolfram|Alpha offered for free on the web. Wolfram|Alpha was recently described in WolframAlpha: A Developer's Preview, by Mike Riley.

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," says Stephen Wolfram, the founder 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."

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's Mathematica technology. Wolfram|Alpha contains nearly 6 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.
