Cambridge English Corpus
The Cambridge English Corpus (CEC) (formerly the Cambridge International Corpus, CIC), is a multi-billion word corpus of English language (containing both text corpus and spoken corpus data). The Cambridge English Corpus contains data from a number of sources including written and spoken, British and American English. The CEC also contains the Cambridge Learner Corpus, a 40m word corpus made up from English exam responses written by English language learners. The Cambridge English Corpus is used to inform Cambridge University Press English Language Teaching publications as well as for research in corpus linguistics. Access is currently  restricted to authors and researchers working on projects and publications for Cambridge University Press, and researchers at Cambridge English Language Assessment. Written Data. The Cambridge English Corpus contains instances of modern written English, taken from newspapers, magazines, novels, letters, emails, textbooks, websites, and many other sources. Spoken Data. The Cambridge English Corpus contains a wide variety of spoken English language, taken from many sources, including everyday conversations, telephone calls, radio broadcasts, presentations, speeches, meetings, TV programmes and lectures. Cambridge Learner Corpus. The Cambridge Learner Corpus (CLC) is a collection of exam scripts written by students learning English, built in collaboration  with Cambridge English Language Assessment. The CLC contains scripts from over 180,000 students, from around 200 countries, speaking 138 different first languages and is growing all the time. The exams currently included are: A unique feature of the Cambridge Learner Corpus is its error coding system. Language specialists identify and annotate errors in the exam scripts. This means that the Corpus can be used to find out about the frequency of different types of errors, the contexts that the errors are made in and the student groups that find particular language areas difficult. Authors of Cambridge English Language Teaching resources  can use this information to target common errors – for example, the Cambridge Advanced Learner’s Dictionary contains ‘Common mistake’ features which highlight frequent learner errors. Conversely, the error coding system also reveals what students can achieve at each level. This is central to the work of English Profile, a collaborative programme to enhance the learning, teaching and assessment of English worldwide. The founding partners are Cambridge University Press, Cambridge English Language Assessment, the University of Cambridge, the University of Bedfordshire, the British Council and English UK. The project’s aim is to describe what learners know and can do in  English at each level of the Common European Framework of Reference (CEFR). Specialized corpora. The Cambridge English Corpus contains a number of specialized corpora: Cambridge Business English Corpus. The Cambridge Business English Corpus is a large collection of British and American business language, including reports and documents, books relating to different aspects of business, and the business sections from many national newspapers. The Cambridge Business English Corpus also includes the Cambridge and Nottingham Spoken Business English Corpus (CANBEC), the result of a joint project between Cambridge University Press and the University of Nottingham. This is a collection of recordings of  English from companies of all sizes, ranging from big multinational companies to small partnerships. It contains formal and informal meetings, presentations, telephone conversations, lunchtime conversations, and spoken language from other business situations. Cambridge Legal English Corpus. The Cambridge Legal English Corpus contains books, journals and newspaper articles relating to the law and legal processes. Cambridge Financial English Corpus. The Cambridge Financial English Corpus contains texts relating to economics and finance, including leading financial magazines and newspapers. Cambridge Academic English Corpus. The Cambridge Academic English Corpus contains written and spoken academic language at undergraduate and post-graduate level from a range  of US and UK institutions, including lectures, seminars, student presentations, journals, essays and text books. CANCODE. The Cambridge and Nottingham Corpus of Discourse in English (CANCODE) is a collection of spoken English recorded at hundreds of locations across the British Isles in a wide variety of situations (e.g. casual conversation, socialising, finding out information, and discussions). The CANCODE corpus is the result of a joint project between Cambridge University Press and the University of Nottingham. There are about five million words in the CANCODE corpus, and it's a very rich resource for researchers of spoken English. However, the data  does have some limitations. Most people knew they were being recorded, and are chatting in informal situations such as while relaxing at home, with others of fairly equal social status. This means the interactions are generally consensual and collaborative, so the corpus has minimal evidence of conflict or adversarial exchanges Cambridge-Cornell Corpus of Spoken North American English. The Cambridge University Press/Cornell Corpus is a large collection of informal, highly interactive, multiparty conversations between family/friends in North America. The Cambridge-Cornell corpus is the result of a joint project between Cambridge University Press and Cornell University. CAMSNAE. The  Cambridge Corpus of Spoken North American English (CAMSNAE) is a large collection of spoken American English. It includes recordings of people going about their everyday life – at work, at home with their families, going shopping, having meals, etc.
