At the same time, electronic publishing has made available to us, on a scale that's quite unprecedented, electronic language data, texts. We can gather those texts together into a body of data called a corpus, the plural of which is corpora, that we use to study language on a computer. For the first time, as the vast collections of data become available, we can easily study language across a range of languages and even back through time. Dictionaries, grammar, spell checkers, grammar checkers, speech synthesis systems, even web search engines, to some extent, rely on these insights into language provided by corpus data. On this course, you'll learn about the range of applications of corpus data in the study of language both in linguistics and beyond it, in the social sciences for example.
