From molecular mechanisms to biological interaction. 1) the network arc between gerE and cwlH in Ex. 3 is inferred from the Interaction:Regulation event. Since the interaction target is an event, the target is reduced to its participant (cwlH); 2) a) Bind_to and Site_of represent low-level biological phenomena from which we can deduce the Master_of_promoter relation of 2) b); c) the Interaction:Binding relation can be deduced from Master_of_Promoter and Promoter_of; 3) the combined interactions from examples 1) and 2) produce the network with 3 edges and two arcs.
