Applications for Education.
As I pointed out in the video above, the Ngram Viewer can offer a great way to begin a research activity for students. Have them get in a few words then analyze the chart to identify peaks and valleys in the frequency of the words use. Then ask to try to determine what would have triggered those words to be used basically frequently at different durations in history.

By the way, the book that I discussed in the video is That Wild Country by Mark Kenyon..

Googles.
Ngram Viewer is a search tool that trainees can use to explore using words and names in books released between 1800 and 2019. The Ngram Viewer shows users a graph highlighting the very first appearance of a word or name in literature and the frequency with which that word or name appears in literature given that 1800. The graph is based upon the books and periodicals that are indexed in Google Books.

Ngram Viewer is a search tool that students can utilize to check out the usage of words and names in books released in between 1800 and 2019. The Ngram Viewer shows users a chart showing the very first appearance of a word or name in literature and the frequency with which that word or name appears in literature considering that 1800. The Ngram Viewer will let you compare the usage of numerous words or names in one chart.

The Ngram Viewer will let you compare the use of multiple words or names in one graph. The example that I offer in this video is to compare making use of the terms “National Parks,” “National Forests,” and “National Forest Service.” By looking at the Ngram Viewer for those terms I can see that they start to appear more frequently around 1890, have a lull in the 1940s and 1950s, and then appear more regularly again in the 1960s..
Ngram Viewer is based on books indexed in Google Books. That is why listed below every chart produced by Ngram Viewer you will find a list of books about each of your search terms. Those books are organized by date..
A third element of Ngram Viewer to keep in mind is that it deals with multiple languages including English, French, Chinese, German, Italian, Russian, Hebrew, and Spanish..
