Evi (formerly ''True Knowledge'') is a technology company in Cambridge, England, founded by William Tunstall-Pedoe,〔(MediaGuardian 100 2009 ) The Guardian (newspaper). 13 July 2009〕〔(A billion facts mean Evi has the answers ) Cambridge News (newspaper). 19 February 2012〕〔(New Virtual Helper Challenges Siri ) Technology Review (MIT). Rachel Metz. 27 January 2012〕 which specialises in knowledge base and semantic search engine software. Its first product was an answer engine that aimed to directly answer questions posed in plain English text, which is accomplished using a database of discrete facts.〔(Cambridge AI specialist seeks funding for latest exciting venture ). 7 May 2007. True Knowledge. Retrieved 2 Dec. 2008〕〔(Technology ). True Knowledge. Retrieved 2 Dec. 2008〕 The True Knowledge Answer engine was launched for private beta testing and development on 7 November 2007.〔(True Knowledge launches open beta ). 7 November 2007. TechCrunch. Retrieved 2 Dec. 2008〕 In January 2012 True Knowledge launched a major new product Evi (pronounced ''ee-vee''), an artificial intelligence program which can be communicated with using natural language via an app on iPhone and Android.〔〔(Apple iPhone Siri, meet competitor Evi, from True Knowledge.

''Wired''.〕〔(Evi arrives in town to go toe-to-toe with Siri ) 23 Jan 2012. Techcrunch〕 The company changed its name from True Knowledge to Evi in June 2012. In October 2012, Evi was acquired by Amazon and is now part of the Amazon group of companies.〔http://www.evi.com/about/〕 == Core technology premise == The True Knowledge Answer Engine attempts to comprehend posed questions by disambiguating from all possible meanings of the words in the question to find the most likely meaning of the question being asked. It does this by drawing upon its database of knowledge of discrete facts. As these facts are stored in a form that the computer can understand, the answer engine attempts to produce an answer to what it comprehends to be the question by logically deducing from them.〔 For example, if one were to type in "What is the birth date of George W. Bush?", True Knowledge would reason from the facts "George W. Bush is a president", "George W. Bush is a human being", "A president is a subclass of human being", "Date of creation is a more general form for birth date", and "the 6th of July is the date of creation for George W. Bush", to produce the simple answer, "the 6th of July". True Knowledge differs from competitors like Freebase and DBpedia in that they offer natural language access. Unlike the others however, users who post information to True Knowledge granted the company a "non-exclusive, irrevocable, perpetual licence to use such information to operate this website and for any other purposes".〔(【引用サイトリンク】title=legal )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Evi (software)」の詳細全文を読む スポンサード リンク
