 Hello again, in this video, I want to show you how you can compare data from different corpora, using English corpora.org. If you want to redo a query in a different corpus, there is a feature for that too, just click on this icon in the upper left corner of the website, to get an overview of the other corpora. Now select the corpus you want to use. For example the British National Corpus, BNC, and click on the check icon. Whenever you want to compare the frequency of a word or phrase in different corpora. Keep in mind though, that in most cases, they do not have the same size. Therefore, you cannot compare absolute frequencies, but you have to look at normalized frequencies. You get the normalized frequencies by changing the display to per, mil, that is, per million words. If you now compare the frequencies in both corpora, you can see that the verb practice is rarely spelt with an S in American English, but with a C. When comparing different corpora, you should also make sure that they are comparable in terms of their compositions, or at least be aware of possible differences, depending on your research question for example. You should not compare language data from different times or genres. This overview provides you with the most important information about the corpus compositions. And as you may have noticed, you can simply change to another corpus and start a new query via this site. So much for comparing corpora, thanks for your attention.
