[edit] What can this extension do?

This tool generates different networks out of articles and their revisions. They can be filtered by category and article edit time.

There are four different Wiki-based networks available: collaboration networks, competence network, article network, and category network.

• The collaboration network is defined by authors which are link by mutual edited articles. The edge weight refers to the number of these articles.
• The competence networks links authors and articles. Here it is possible to discover quickly which author has competencies in which topic area.
• The change activity network combines articles based on existing Wiki-links. The colour of nodes depends on the number of edits and is the darker the more frequently articles are changed.
• The category network simply shows the existing categories in a Wiki and relations between sub-categories.
