This causes the first member of the topologies associated with the S-nodes to receive a coreference tag (indicated by boxed numbers): If, as in the example of Figure 1, know's complement is indeed declarative, the foot of the complement segment can successfully unify with the root of the hate frame.
the F1 slot of the complement clause is the same object as the F1 slot of the main clause, and any fillers will seem to have moved up one level in the clause hierarchy: Filling a slot also involves coreference tags.
