(Up) Two screenshots of the Social Network Analysis based on the Circle Layout and Hanover of Task matrix. The more the nodes receive tasks, the more vertical they look like. The more the nodes assign tasks to others, the more horizontal they look like. (Down) Two screenshots of the Social Network Miner (based on the Hanover of Task metric) on the peer-review event log. The more out-going arrows lead to appearance of the more horizontal oval shapes.
