This page is to show some examples about the relationship analysis of history events and 1-grams word usage frequency.
The idea is initially borrowed from Jean-Baptiste Michel's "Quantitative Analysis of Culture". Currently, the search engine is limited to 1-grams, and case sensitive either.
I set up a simple web search engine for 1-grams:
