N-grams are graphs that are derived from collections of text, showing how the frequency of a word or phrase changes over time. Google’s N-Gram Viewer was implemented last fall. Or at least, that’s when I noticed it whenever I typed “Define:” into the omnisearch bar – there was a graph showing how the use of the word I looked up had changed over the years. Drawing on the more than 5 million books that Google has digitized, you can enter phrases, words, names, etc into the Google NGV and explore the results.
