The freely searchable 450-million-word Corpus of Contemporary American English (COCA) is the largest corpus of American English currently available, and the only publicly available corpus of American English to contain a wide array of texts from a number of genres. It was created by Mark Davies, Professor of Corpus Linguistics at Brigham Young University.〔 〕 ==Content== The corpus is composed of more than 450 million words from more than 160,000 texts, including 20 million words each year from 1990 to 2011. The most recent update was made in Summer 2012. The corpus is used by approximately tens of thousands of people each month, which may make it the most widely used "structured" corpus currently available. For each year, the corpus is evenly divided between the five genres: spoken, fiction, popular magazines, newspapers, and academic journals. The texts come from a variety of sources: * Spoken: (85 million words) Transcripts of unscripted conversation from nearly 150 different TV and radio programs. * Fiction: (81 million words) Short stories and plays, first chapters of books 1990–present, and movie scripts. * Popular magazines: (86 million words) Nearly 100 different magazines, from a range of domains such as news, health, home and gardening, women's, financial, religion, and sports. * Newspapers: (81 million words) Ten newspapers from across the US, with text from different sections of the newspapers, such as local news, opinion, sports, and the financial section. * Academic Journals: (81 million words) Nearly 100 different peer-reviewed journals. These were selected to cover the entire range of the Library of Congress Classification system. 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「Corpus of Contemporary American English」の詳細全文を読む スポンサード リンク
