NAVIGATING ELECTRONIC DOCUMENTS USING DOMAIN DISCOURSE TREES

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.
