The corpora present a collection of texts or recordings that reflect the context in which language is used. The whole is encoded and makes a classification and, this way, it allows users search among longer texts. This way we can find concrete examples on the usage of words, expressions, verbal elements, idioms and so on.
This website by Mark Davies, from BrighamYoung University, allows us to quickly and easily search for a wide range of words and phrases of English in the 100 million word British National Corpus.
This corpus of English language allows us to search for words and phrases by exact word or phrase and parts of speech. We can also look for surrounding words (collocates), compare between registers and synonims, allowing us to find the frequency and distribution of words. It is fast and free. It offers to us not only a search through written contexts but also through spoken ones, giving to us the percentage of use of a concrete word, expression… and the number of times the corpus has found it.
I think this tool is quite -appart from accurate- useful since it helps us find the difference between similar words, know in which context we can use them and things that we cannot find in a dictionary or in other similar tools and that only a native speaker of English would know. I think for us, it is impossible to get to know the mistakes a corpus like this could make.
