Ways of using the BNC
The corpus texts are in XML format and can be used with various software applications that can handle that format, or tools that work with plain text files. Worth noting is that unless you use a tool that can interpret the markup, you may not be able to, for example, define a search that retrieves instances of a word spoken by a woman, something occurring in a book, or a phrase found in a certain domain.
BNC online services
The BNC can also be searched online. The BNC Simple Search is a free online service which allows users to search the full BNC World corpus and see the frequency of the search term and up to 50 randomly selected instances. To use the service, simply go to the BNC start page and type your search string into the search box. More information is also available in the Simple Search section.
