Hybrid trees
One
can render Reed-Kellogg diagrams according to modern tree
conventions. When one does so, the result is a hybrid
dependency-constituency tree. The Reed-Kellogg diagrams above appear
as the following trees:
A mixing of
labeling conventions (i.e. category label vs. actual word) helps draw
attention to the presence of both constituency and dependency. The S
and VP in these trees mark the constituency relation and the words
themselves mark the dependency relation. A major difference between
these hybrid trees and the Reed-Kellogg diagrams, however, is that
the hybrid trees encode actual word order, whereas the Reed-Kellogg
diagrams are abstracting away from actual word order in order to
focus more on function.
