| | === Questions to answer === |
| __NOTOC__
| | <ol> |
| | | <li> Warm Up |
| 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.
| | <ol type="a"> |
| | | <li> When was the article about the Panama Papers created? </li> |
| == Goals == | | <li> When was the most recent edit to the Panama Papers article? </li> |
| | | <li> Think of one or two articles that interest you. Which ones were created first? </li> |
| * Get set up to build datasets with the Wikipedia API
| | <li> Which have been edited most recently? |
| * 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 API project == | |

| | |
| (Estimated time: 10 minutes)
| |
| | |
| ===Download the Wikipedia API project===
| |
| | |
| * Right click the following file, click "Save Target as..." or "Save link as...", and save it to your Desktop directory:
| |
| https://github.com/CommunityDataScienceCollective/wikipedia-cdsw/archive/master.zip
| |
| | |
| * The ".zip" extension on the above file indicates that it is a compressed Zip archive. We need to "extract" its contents. To do this, click on "Start", then "Computer" on Windows or open Finder and navigate to your Desktop directory if you are a Mac. Find <code>wikipedia-cdsw-master.zip</code> on your Desktop and double-click on it to "unzip" it. That will create a folder called <code>wikipedia-cdsw-master</code> containing several files.
| |
| | |
| ===Test the Wikipedia API code===
| |
| | |
| Startup your jupyter notebook [[Python_in_Jupyter| as usual]]. Using jupyter open in your browser, navigate to the <code> wikipedia-cdsw-master</code> folder that you saved on your Desktop and open <code>wikipedia-test-anon_nonanon.ipynb</code>.
| |
| | |
| Run all the cells in the notebook. Cell 4 should take some time and output messages like <code>pulling data iteration 0</code>. Cell 5 should output a dictionary of IP addresses and counts and cell 6 should output a dictionary of user names and counts.
| |
| | |
| If you don't get this output or see any error messages ask a mentor for help right away.

| | |
| == Topics to cover in the session ==
| |
| | |
| === Main Wikipedia API ===
| |
| * explain [http://www.mediawiki.org/wiki/API:Main_page MediaWiki], exists on other wikis
| |
| * navigate to [http://en.wikipedia.org/w/api.php api page] and show the [https://www.mediawiki.org/wiki/API:Revisions documentation], point out examples
| |
| * introduce the [https://en.wikipedia.org/wiki/Special:ApiSandbox API sandbox] as a tool for building queries
| |
| * looking at the images within a page http://en.wikipedia.org/w/api.php?action=query&titles=Seattle&prop=images&imlimit=20&format=jsonfm
| |
| * change the city with a custom URL
| |
| * edit count http://en.wikipedia.org/w/api.php?action=query&list=users&ususers=Benjamin_Mako_Hill|Jtmorgan|Sj|Koavf&usprop=editcount&format=jsonfm
| |
| * get the content of the main page http://en.wikipedia.org/w/api.php?format=json&action=query&titles=Main%20Page&prop=revisions&rvprop=content
| |
| | |
| === Page View API ===
| |
| * Use [https://wikimedia.org/api/rest_v1/?doc#!/Pageviews_data the REST API]
| |
| * Explain that this API is a little different because it uses relative paths instead of parameters.
| |
| * Also note that this API is case-sensitive.
| |
| * Request for Panama Papers: https://wikimedia.org/api/rest_v1/metrics/pageviews/per-article/en.wikipedia/all-access/user/Panama_Papers/daily/20160401/20160420
