What is Google Ngram Viewer? | Bootcamps

Google Ngram Viewer is an online search engine that allows you to represent in a graph the annual frequency of different ngrams detected in the corpora that Google has available for a multitude of languages.

Google Ngram Viewer Features

Google Ngram Viewer is a very useful tool to, for example, see word trends. What it allows us to do is search for ngrams throughout all the books that have been published (Google books) on any date..

Let’s look at an example:

We have that the temporal delimitation of this search goes from the year 1800 to 2000. The ngram is defined with 3 entries: one is Albert Einstein, another is Sherlock Holmes and another is Frankenstein.

So, in this nogram, which in this case is a trigamma, We get the frequency of each of its entities over time.

We noticed, for example, that the novel of Frankenstein was known in 1820 (this novel was published on January 1, 1818), in fact it was booming. However, Albert Einstein does not appear until 1915-1920, and Sherlock Holmes did not begin to appear in books until 1890.

In the same way we can analyze and evaluate trends of any type. Let’s imagine that we are talking about speeches. Now we will put the Trump and republican:

It shows us a diagram where the frequency of repetition of the word republican It is very fluctuating over time, while the word Trump has had very little influence. It was not until 1990 when both words began to grow in use and some type of correlation between them began to be noticed.

Now let’s look at another very interesting one between «dollar» and «inflation»:

We see that the appearance of the word dollar has been progressive and that the word inflation It had an explosion around the 80s (1980 was one of the periods with the highest inflation in the United States).
