Chomsky held the view that the corpus cold never be a useful tool for the linguists, as the linguist must seek to model language competence rather than performance. Second, the only way to account for a grammar of a language is by description of its rules--not by enumeration of its sentences. Third, language is not a finite construct. However, it was the wonder of computer that heralded the revival of corpus linguistics. The computer has the ability to search for a particular word, sequence of words, or perhaps even a part of speech in a text. The computer can also retrieve all examples of a particular word, usually in context, which is further aid to the linguist. It can also calculate the number of occurrences of the word so that information on the frequency of the word may be gathered. We may then be interested in sorting the data in some way, for example, alphabetically on words occurring in the immediate context of the word.
