Fig. 3From: The Third Man: hierarchy formation in WikipediaEdit events resulting from the deletion of a word (left) and a word being restored (right). Solid lines encode dyadic redo events by which the active user re-does the target user’s edit. Dashed lines encode dyadic undo events by which the active user makes the target user’s edit undone. Dotted lines encode third-party edit events by which the active user re-does the source user’s edit that has been made undone by the target user. After deleting a word w the user active becomes deleter(w) and after restoring w user active becomes restorer(w). Note that author(w) is only set when w is originally added and does never change againBack to article page
