The dataset we used in the Wiki4HE Project is been published in the UCI Machine Learning Repository , which is “a collection of databases, domain theories, and data generators that are used by the machine learning community for the empirical analysis of machine learning algorithms”, with more than 300 dataset available in its web page.
So, the dataset we used for our analysis on the teaching use of Wikipedia in higher education is now an open resource, freely available on line. The Wiki4HE dataset has 913 instances and 53 attributes. You can get all the information about the attributes description in the web. Feel free to download here (Data Folder and Data Set Description).
