The columns in Figure 2 determine how the responding systems come to present the
answers. This will be through the mechanism of ad hoc higher order noetic structures,
or of prepared structures that have been optimised for such questions. Each of the
knowledge relations in the columns will have a commonality of structural principle
because of their being based in type 1 (shape-dominant), type 2 (granularity-dominant)
or type 3 (scope-dominant) structures, as described next (note that all noetic structures
will always from first principles have all three vertices significant to some extent, it is
the dominant vertex that informs the answering process):
