Wikipedia network of top categories

Dataset information

This is a web graph of Wikipedia hyperlinks collected in September 2011. The network was constructed by first taking the largest strongly connected component of Wikipedia, then restricting to pages in the top set of categories (those with at least 100 pages), and finally taking the largest strongly connected component of the restricted graph.

In addition to the graph, we also provide the page names of the articles and the categories of the articles. The categories can serve as "ground-truth" communities. The categories are overlapping as each article may be classified into several categories.
