Ngram and beyond

The more I play with Ngram visualizer, the more I enjoy it. There are many charts on the Internet comparing things like supply vs demand, comparisons of most cited scientists , comparisons of most cited economists or stocks and bonds. And finally a really nice TedTalk about Google Ngram.



Some people came up with a name, instead of "playing with ngram" they call this culturonomics

Who gives more support to disable people?

Now that the Paraolympics are over I wonder how Paraolympics medals tally is compared to Olympic medals one per country. I know this is not a proper way of measuring support to disable people but I though it could be interesting. The result is pretty shocking. The graph below shows only the top 43 countries in the olympic medals' ranking. Clearly, China shouldn't be that high given their poor care to disable. It is also strange to see Denmark so low in the ranking.

One thousand Ngram charts

Google Books state that they have digitalised the 4% of all books ever published, more than 5 million books (and journals) since 1500AD. With that amount of data they quickly came up with the idea of a visualization tool. Google Ngram is the visualization tool of Google Books and is a easy and fast way of visualizing information and tendencies in the use of words and group of words through history. Informationisbeautiful took some nice comparisons between different words:

Plato (blue) vs Aristotle (red)since 1800AD
Religion (blue) vs Science (red)since 1750AD What (blue) vs When (red) vs Why (green) vs How (yellow)since 1800AD
1900 (blue) vs 1910 (red) vs 1920 (green) vs 1930 (yellow)...since 1900AD
