WolframAlpha [a] is an answer engine developed by Wolfram Research. [1] It is offered as an online service that answers queries by computing answers from externally sourced data. [2] [3]
Launch preparations for WolframAlpha began on May 15, 2009, at 7:00 pm CDT with a live broadcast on Justin.tv. The plan was to publicly launch the service a few hours later. [4] [5] However, there were issues due to extreme load. The service officially launched on May 18, 2009, receiving mixed reviews. [6] [7] [8]
The engine is based on Wolfram's earlier product Wolfram Mathematica, a technical computing platform. [4] The coding is written in Wolfram Language, a general multi-paradigm [ further explanation needed ] programming language, and implemented in Mathematica. [9] WolframAlpha gathers data from 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 , [1] CrunchBase, [10] Best Buy, [11] and the FAA to answer queries. [12]
On February 8, 2012, WolframAlpha Pro was released, [13] offering users additional features for a monthly subscription fee. [13] [14]
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 can respond to particularly phrased natural language fact-based questions. It displays its "Input interpretation" of such a question, using standardized phrases. It can also parse mathematical symbolism and respond with numerical and statistical results.[ citation needed ]
WolframAlpha was used to power some searches in the Microsoft Bing and DuckDuckGo search engines but is no longer used to provide search results. [15] [16] For factual question answering, WolframAlpha was used by Apple's Siri in October 2011 and Amazon Alexa in December 2018 for math and science queries. [17] [18] Users noticed that the Wolfram Integration for Siri was changed in June 2013 to use Bing to query certain results on iOS 7. [19] Starting with iOS 17, it was reported that Wolfram for Siri no longer answers mathematical equations, instead defaulting to web search queries with no notable explanation. [20] [21] WolframAlpha data types[ clarification needed ], sets of curated information and formulas that assist in creating, categorization, and filling of spreadsheet information, became available in July 2020 within Microsoft Excel. [22] The Microsoft-Wolfram partnership ended nearly two years later, in 2022, in favor of Microsoft Power Query data types. [23] WolframAlpha functionality in Microsoft Excel ended in June 2023.
