Today the competition finished and I would like to say thank you to everyone who so far participated in the voting in particular to the 435 people supporting our course. I did never image to get that many people to be interested in our course!
The voting period went from May first till today. During this period the user interface of the iversity website changed several times providing different kind of information about the voting to us users. Since I have observed a drastic change in rankings on May 9th and since the process and scores have not been very transparent I have decided on that very day to collect some data about the rankings. I already did some quick analysis on the data and found some interesting facts but I am running out of time right now to conduct an extensive data analysis. So I will share the data set with the public domain:
http://rene-pickhardt.de/mooc.tar.bz2 (33MB)
If you download the zip file and extract it you’ll find folders for every hour after May 9th. In every folder you will find 26 html-files representing the current ranking of the courses at that time and a transaction log of the http-requests which were done to download the 26 html files. There are 26 html files since 10 courses were displayed per page and we had 255 courses participating.
During the time of data collection I had 2 or 3 short down times of my web server so it could be possible that some data points are missing.
I already wrote a “dirty hack” and pushed it on github which also extracts the interesting information out of the downloaded html files.

  1. There is a file rank.tsv (334 kb) that displays for every course on an hourly basis the rankings
  2. There is a file vote.tsv (113 kb) that contains for every course on an hourly basis (between may 20th and today) the number of votes the course did acquire. The period of time for vote.tsv is so short since the votes have only been available in the html files during this time. 

Skimming the data with my eyes there are already some facts that make me very curious for a deeper data analysis:

  1. Some courses gained several hundred votes within a short period of time (usually only 2 or 3 hours) whereas most courses (especially those gaining such a large amount of votes) often stayed far under 1000 votes at all. 
  2. Also it is interesting to see how much variation has been going on in the last couple of days. 
  3. Also I haven’t crawled the views of the Youtube videos of the courses and even now after observing the following I did not take a snapshot of them it is interesting that there is such a large difference in conversion rate. Especially the top courses seem to have much more votes than they have views of the application video. Where some really high class and outstanding applications like the ones from Chrstian Spannagel (Math) or  Oliver Vornberger (Algorithms and data structures) have two or three times as many views on Youtube as votes. Especially they have about the same amount of views on Youtube as the top voted courses.

I am pretty sure there are some more interesting facts and maybe someone else has collected a better data set over the complete periode of time and including Youtube snapshots as well as Facebook and Twitter mentions.
Since I have been asked several times already: here are the final rankings to download and also as a table in the blog post:
