Community Data Science Workshops (Spring 2015)/Day 2 Projects/Wikipedia

Building a Dataset using the Wikipedia API
In this project, we will explore a few ways to gather data using the Wikipedia API. Once we've done that, we will extend this to code to create our own datasets of Wikipedia edits or other data that we might be able to use to ask and answer questions in the final session.

Goals

 * Get set up to build datasets with the Wikipedia API
 * Have fun collecting different types of data from Wikipedia
 * Practice reading and extending other people's code
 * Create a few collections of different types of data from Wikipedia that you can do research with in the final section

Download and test the Wikipedia project
