WolframAlpha (/ˈwʊlfrəm-/ WUUL-frəm-) is a computational knowledge engine[3] or answer engine developed by WolframAlpha LLC, a subsidiary of Wolfram Research. It is an online service that answers factual queries directly by computing the answer from externally sourced "curated data",[4] rather than providing a list of documents or web pages that might contain the answer, as a search engine might.[5]
WolframAlpha, which was released on May 18, 2009, is based on Wolfram's earlier flagship product Wolfram Mathematica, a computational platform or toolkit that encompasses computer algebra, symbolic and numerical computation, 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]
