ABSTRACT
This chapter describes a representational system that incorporates implicit knowledge into passage representations. Schematicians address a number of questions about implicit knowledge when investigating prose comprehension and representation. Many representational systems are so complex that they have alienated virtually all researchers except for the one who invented the theory. Each statement node is assigned to one of six node categories: physical State, physical Event, internal State, internal Event, goal and style. Conceptual Graph Structures is convenient to segregate graph structures or portions of graph structures into three types: goal-oriented structures, cause-oriented structures and static, descriptive structures. According to Decker the primary purpose of expository text is to expose information or ideas. Comprehenders draw more inferences in narrative prose than expository prose. Moreover, the other representational theories in this volume have also not been able to explain the global rhetorical organization of prose, sequential coherence, pragmatic coherence, and the linguistic rules for generating surface structures from the underlying semantic structures.
