WolframAlpha (/ˈwʊlf.rəm-/ WUULf-rəm-) is a computational knowledge engine and answer engine developed by Wolfram Research.[3] It answers factual queries directly by computing the answer from externally sourced data.[4][5]

WolframAlpha was released on May 18, 2009, and is based on Wolfram's earlier product Wolfram Mathematica, a computational platform for calculation, visualization, and statistics capabilities.[1] Additional data is gathered from both academic and commercial websites such as the CIA's The World Factbook, the United States Geological Survey, a Cornell University Library publication called All About Birds, Chambers Biographical Dictionary, Dow Jones, the Catalogue of Life,[3] CrunchBase,[6] Best Buy,[7] and the FAA.[8]

Technology

Overview

Users submit queries and computation requests via a text field. WolframAlpha then computes answers and relevant visualizations from a knowledge base of curated, structured data that come from other sites and books. It is able to respond to particularly phrased natural language fact-based questions, or more complex questions. It displays its "Input interpretation" of such a question, using standardized phrases. Mathematical symbolism can be parsed by the engine, which responds with numerical and statistical results.

Development

WolframAlpha is written in the Wolfram Language, a general multi-paradigm programming language, and implemented in Mathematica and ran on more than 10,000 CPUs as of 2009.[9]

Usage

WolframAlpha has been used to power some searches in the Microsoft Bing and DuckDuckGo search engines but is not currently used.[10][11] For factual question answering, it is sometimes queried by Apple's Siri and Amazon Alexa for math and science queries.[12][13]

History

Launch preparations began on May 15, 2009, at 7 p.m. CDT and were broadcast live on Justin.tv. The plan was to publicly launch the service a few hours later. There were issues due to extreme load. The service was officially launched on May 18, 2009,[14] receiving mixed reviews.[15][16] In 2009, Wolfram Alpha advocates pointed to its potential, some even stating that how it determines results is more important than current usefulness.[15]

On February 8, 2012, WolframAlpha Pro was released,[17] offering users additional features for a monthly subscription fee.[17][18]

Copyright claims

InfoWorld published an article warning readers of the potential implications of giving an automated website proprietary rights to the data it generates.[19] Free software advocate Richard Stallman also opposes the idea of recognizing the site as a copyright holder and suspects that Wolfram would not be able to make this case under existing copyright law.[20]
