Corpus Tools Guides

In simple terms, a corpus is a collection of texts that is stored electronically. This corpus, or a set of corpora, can then be used to see how writers and speakers use words in context.

Corpus tools allow you to see how a certain word is used in context, the frequency of the word, the company the word keeps (or collocation), the register, genre, or discipline it is frequently used in, and so on. They can also be used to submit your own paper to see how you are using certain words.
