1. In a computer that accesses a hybrid network representation, the hybrid network representation comprising a schema describing a plurality of nodes of differing node types, a method comprising: a. Receiving a user selection of a first node of a first type and a second node of a second type; b. Determining a plurality of possible pathways between the first node and the second node; c. Ordering the plurality of possible pathways according to a link count of each pathway, wherein each link count is equal to a quantity of links observed between each node pathway pair of a comprising pathway; and d. Further ordering the plurality of possible pathways by ranking pathways having a one-to-one link between two pathway nodes, whereby pathways having at least one one-to-one link are ordered for earlier examination than pathways having equal link counts and comprising one-to-one links.
2. The method of claim 1 , wherein a human administrator modifies the ordering of the plurality of possible pathways.
