== 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. | In this project, we will explore a few ways to gather data using the Wikipedia API.

Find <code>wikipedia-data-examples.zip</code> on your Desktop and double-click on it to "unzip" it. That will create a folder called <code>wikipedia-data-examples</code> containing several files. | * The ".zip" extension on the above file indicates that it is a compressed Zip archive.
