Scott Elliott Fahlman (born March 21, 1948) is a computer scientist at Carnegie Mellon University. He is notable for early work on automated planning in a blocks world, on semantic networks, on neural networks (and, in particular, the cascade correlation algorithm), on the Dylan programming language, and on Common Lisp (in particular CMU Common Lisp and he was one of the founders of Lucid Inc.). During the period when it was standardized, he was recognized as "the leader of Common Lisp."〔 〕 Recently, Fahlman has been engaged in constructing a knowledge base, "Scone", based in part on his thesis work on the NETL Semantic Network. Fahlman was born in Medina, Ohio, U.S.. He received his bachelor's degree and master's degree in 1973 from MIT, and his Ph.D. from MIT in 1977. His thesis advisors were Gerald Sussman and Patrick Winston. He is a fellow of the American Association for Artificial Intelligence. Fahlman acted as thesis advisor for Donald Cohen, David B. McDonald, David S. Touretzky, Skef Wholey, Justin Boyan, Michael Witbrock, and Alicia Tribble Sagae. From May 1996 to July 2001, Fahlman directed the Justsystem Pittsburgh Research Center. ==Emoticons== Fahlman is credited with originating the first smiley emoticon,〔(Business Week Online, April 23, 2001 )〕〔(Scott Fahlman's Smiley Lore page, containing his version of the history, accessed Sept. 19, 2007 )〕〔 〕 which he thought would help people on a message board at Carnegie Mellon to distinguish serious posts from jokes. He proposed the use of :-) and :-( for this purpose, and the symbols caught on. The original message from which these symbols originated was posted on September 19, 1982. The message was recovered by Jeff Baird on September 10, 2002〔(Fahlman's original message ) Retrieved February 19, 2009.〕 and is quoted:
Though credited with originating the smiley emoticons, he was not the first emoticon user; a similar marker appeared in an article of ''Reader's Digest'' in May 1967.〔(Urban Legends Reference Pages: Emoticon (Smiley) Origin )〕 In an interview printed in the ''New York Times'' in 1969, Vladimir Nabokov noted, "I often think there should exist a special typographical sign for a smile — some sort of concave mark, a supine round bracket." 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「Scott Fahlman」の詳細全文を読む スポンサード リンク
