Chinese museum analysis

A word-count analysis of the names of around 4500 museums in China.

natural language processing text analysis word counting

Readings and links

Summary

Caixin converted a long, long PDF of over 4,000 museums in China to a CSV, determining what were the most popular words used in museum names. We take a look at both their text approach as well as their per-capita analysis.

Notebooks, Assignments, and Walkthroughs

Chinese museum dataset cleanup

Cleaning up the data exported by Tabula so we can do some further analysis on it.

About the site

Hi, I'm Soma, welcome to Data Science for Journalism a.k.a. investigate.ai!

There's been a lot of buzz about machine learning and "artificial intelligence" being used in stories over the past few years. It's mostly not that complicated - a little stats, a classifier here or there - but it's hard to know where to start without a little help.

If you know a little Python programming, hopefully this site can be that help! Learn more about this project here.
