The English-Corpora.org online version is comprised of several corpora including: iWeb, the Intelligent Web Corpus; NOW, News on the Web; Coronavirus Corpus; COCA ,Corpus of Contemporary American English; GloWbE, Global Web-based English; Wikipedia Corpus; COHA: Corpus of Historical American English; TV Corpus; Movies Corpus, SOAP Corpus, as well as Corpus del Español and Corpus do Português. The corpora have many different uses, including: finding out how native speakers actually speak and write; finding the frequency of words, phrases, and collocates; looking at language variation and change; e.g. historical, dialects, and genres; gaining insight into culture; for example what is said about different concepts over time and in different countries; designing authentic language teaching materials and resources. To access the corpora as a downloadable set for offline use see the resource "English-Corpora Text-as-Data."
ProQuest TDM Studio allows research teams at NYU the ability to mine large volumes of published content from the millions of pages of news, scholarly and other publications provided to the campus community through current ProQuest subscriptions.
The Linguistic Data Consortium (LDC) is an open consortium of universities, libraries, corporations and government research laboratories. It was formed in 1992 to address the critical data shortage then facing language technology research and development. LDC creates and distributes a wide array of language resources, including materials used by those engaged in language-related education, research and technology development. Spanning data collections, corpora, software, research papers and specifications, these vital tools aid and inspire scientific progress. Please note that NYU does not currently own all available products available from LDC.
To access LDC data, you must be identified as a member of the NYU Community. To get started, go to the account homepage and create an account using your NYU email. Please be sure to enter "New York University" (without the quotes) into the "Organization" box and then select it as an organization. After you make your account, you will be contacted with next steps.
These datasets were generated in July 2012 (Version 2) and July 2009 (Version 1); we will update these datasets as our book scanning continues, and the updated versions will have distinct and persistent version identifiers (20120701 and 20090715 for the current sets). Each of the numbered links below will directly download a fragment of the corpus. In Version 2 the ngrams are grouped alphabetically (languages with non-Latin scripts were transliterated); in Version 1 the ngrams are partitioned into files of equal size. In addition, for each corpus we provide a file named total_counts, which records the total number of 1-grams contained in the books that make up the corpus. This file is useful for computing the relative frequencies of ngrams.
This dataset was collected and prepared by the CALO Project (A Cognitive Assistant that Learns and Organizes). It contains data from about 150 users, mostly senior management of Enron, organized into folders. The corpus contains a total of about 0.5M messages. This data was originally made public, and posted to the web, by the Federal Energy Regulatory Commission during its investigation.
