Navigating electronic documents using domain discourse trees

Abstract:

Systems, devices, and methods of the present invention relate to extended discourse trees and using extended discourse trees to navigate text. In an example, a discourse navigation application creates a first discourse tree for a first paragraph of a first document and a second discourse tree for a second paragraph of a second document. The application determines an entity and a corresponding first elementary discourse unit from the first discourse tree. The application determines, in the second discourse tree, a second elementary discourse unit that matches the first elementary discourse unit that exists. The application determines a rhetorical relationship between the two elementary discourse units and creates a navigable link between the two discourse trees.
